FLOPAM FO 4240 SH Alternative Selection (CNfloc C8008 / C8003)
ChinaPAM accepts FLOPAM FO 4240 SH enquiries, quotes two bracketing cationic powder routes, and discusses sample arrangements after the grade and conditions are confirmed. The incumbent position is Low charge plus High molecular weight; ChinaPAM brackets those two axes with two stated alternatives — CNfloc C8008 holds the Low charge band but sits at Medium molecular weight, while CNfloc C8003 holds the High molecular weight band but sits at High charge. The SH suffix remains part of the product identity throughout.

FLOPAM is a trademark of SNF, and SNF is the publisher of the 2007 powder catalogue cited on this page. ChinaPAM is an independent manufacturer and is not affiliated with, endorsed by, licensed by or a distributor for SNF. The brand and grade names are used only to identify the product a buyer is comparing.
| Parameter | ChinaPAM Supply Route | SNF FLOPAM FO 4240 SH |
|---|---|---|
| Chemistry | Cationic polyacrylamide powder — CNfloc C8008 primary, CNfloc C8003 backup | Cationic polyacrylamide powder, per the 2007 catalogue entry |
| Charge class | C8008 sits in the Low charge band of ChinaPAM’s own cationic ladder, which is why it leads. C8003 does not — it is a High charge grade, and that is the gap carried by the backup route. | Low charge, as a relative label within the publisher’s range. Low charge and High molecular weight are relative labels inside one supplier’s own range. They cannot be converted into a percentage, a molecular weight figure or another supplier’s label, so no numeric alignment is offered on this page. |
| Molecular weight class | C8003 sits in the High molecular weight band, which is why it is held as the backup. C8008 does not — it is a Medium molecular weight grade, and that is the gap carried by the primary route. | High molecular weight within the SH & SHU table — distinctly above the Standard position of the bare FO 4240 |
| Both axes together | Not available from one grade. The two routes are alternatives and are never combined or presented as a joint match; the trial decides which single gap your duty tolerates. | Low charge and High molecular weight in the same catalogue row |
| Suffix position | Held throughout. The quoted route answers SH, not the bare grade and not SSH. | The SH suffix is part of the identity, not a decoration. SH, SSH and the bare FO 4240 occupy different positions, and dropping or substituting a suffix changes which product is being discussed. |
| Bulk density | Confirmed against the quoted ChinaPAM grade’s own data | 0.85 in the 2007 catalogue. The figures quoted from the 2007 catalogue are historical and indicative. They are reproduced here as context for an incumbent product, not as a current competitor specification and not as a ChinaPAM specification. |
| Solution viscosity | Confirmed against the quoted ChinaPAM grade’s own data | Brookfield 415 / 180 / 70 cps at 5.0 / 2.5 / 1.0 g/L in the 2007 catalogue — historical indicative only |
| Preparation concentration | ChinaPAM powder preparation runs at a 1–3 g/L recommended window, 5 g/L maximum, and no longer than 60 minutes at working concentration. Preparation concentration is not process dosage. | 4 g/L recommended and 10 g/L maximum in the 2007 catalogue, with 90 minutes dissolution in deionized water at 5 g/L and 25 °C. Incumbent context, not a ChinaPAM figure. |
| Storage and shelf life | Confirmed against the quoted ChinaPAM grade and the destination conditions | 0–35 °C storage and a 24-month shelf life in the 2007 catalogue, conditional on a footnote requiring stable indoor storage at 5–30 °C. The condition travels with the figure. |
| Packaging | Agreed in the quotation against grade, destination and order conditions | 25 kg bags and 750 kg big bags in the 2007 catalogue — historical, not a current offer |
| Performance on your sludge | Unknown until a comparative trial; that is the acceptance basis | Not establishable from a catalogue entry for either side |
| Documents | Applicable document set and TDS availability are confirmed against the quoted ChinaPAM grade; a batch-specific COA is tied to a confirmed shipment only. Price and sample arrangements are open for discussion now; current competitor specification, competitor stock and ChinaPAM lead time stay unclaimed until separately confirmed. | A 2007 product catalogue. It establishes the grade’s position and its historical figures — nothing about ChinaPAM. |
Specifications
| Selection Route | Cationic polyacrylamide powder, offered as a two-axis bracket because no ChinaPAM grade is Low charge and High molecular weight at once |
| Incumbent Target Position | Low charge and High molecular weight together, per the 2007 catalogue row |
| Primary Grade | C8008 — Low charge band held; Medium molecular weight, so the chain-length axis is the open gap |
| Backup Grade | C8003 — High molecular weight band held; High charge, so the charge axis is the open gap |
| Two-Axis Status | Not closed by either route. The routes are alternatives, never combined into one answer. |
| Suffix | SH — mandatory. SSH and the bare FO 4240 are different positions. |
| Charge Class (source) | Low charge, as labelled within the publisher’s own range |
| Molecular Weight Class (source) | High molecular weight, as labelled within the publisher’s own range |
| Physical Form | Powder |
| Source Bulk Density | 0.85 — historical indicative value from the 2007 catalogue |
| Source Brookfield Viscosity | 415 / 180 / 70 cps at 5.0 / 2.5 / 1.0 g/L — historical indicative |
| Source Preparation | 4 g/L recommended, 10 g/L maximum — incumbent context, not a ChinaPAM figure |
| ChinaPAM Preparation Window | 1–3 g/L recommended, 5 g/L maximum, under 60 minutes at working concentration |
| Screening Basis | Two-route charge-and-MW bracket: CNfloc C8008 holds the Low charge band at Medium molecular weight; CNfloc C8003 holds the High molecular weight band at High charge. No single ChinaPAM grade occupies both bands. Fit confirmed by trial on the actual sludge. |

| Equivalence Claim | None. No identical product, no drop-in and no guaranteed performance before a trial. |
Key Features
- Selection route named up front as a bracket, not a match: CNfloc C8008 primary, CNfloc C8003 backup, each with its own stated gap.
- The SH suffix is held throughout — an SH requirement is not answered from the bare FO 4240 position.
- Both axes are checked, not just one: low charge and high molecular weight together define the target, and no single ChinaPAM grade holds both.
- The gap is named on each route rather than hidden: C8008 is Medium molecular weight against a High target, C8003 is High charge against a Low target.
- 2007 catalogue figures are shown as incumbent context and labelled historical, never as a current specification.
- ChinaPAM accepts the enquiry now: price, samples, applicable document set and application-condition checks.
- No identical-formula, drop-in or guaranteed-performance claim, and no numeric alignment invented between suppliers.
- No current competitor specification, competitor stock or ChinaPAM lead-time claim until separately confirmed.
Applications
- Municipal and industrial sludge dewatering where a low-charge cationic powder is the incumbent
- Belt press and screw press conditioning at high molecular weight
- Primary and mixed sludge thickening ahead of dewatering
- Changeover screening where FO 4240 SH is currently in service
- Comparative trials where charge band and chain length are both in question

The supply answer first: two routes, each with its own gap
A confirmed FLOPAM FO 4240 SH requirement is Low charge and High molecular weight at the same time. The ChinaPAM cationic powder ladder has no grade in both bands, so the honest answer is two routes rather than one match. CNfloc C8008 is the primary route because it holds the Low charge band exactly — its gap is chain length, since it sits at Medium molecular weight. CNfloc C8003 is the backup because it holds the High molecular weight band — its gap is charge, since it sits at High charge against a Low charge target. Price and sample arrangements are open for discussion from the first message, and the applicable document set and your application conditions can be checked at the same time.
The state is a selection service. ChinaPAM does not supply the branded FLOPAM grade, does not claim an identical or drop-in product, and does not guarantee performance ahead of a trial. Nor are the two routes added together: C8008 and C8003 are alternatives, and quoting both does not produce a grade that satisfies both axes. What a trial decides is which single gap your sludge and your equipment tolerate.
ChinaPAM’s own manufacturing and document position is on the supplier profile and the certifications and compliance page. The 2007 SNF catalogue cited here is a competitor document and establishes nothing about ChinaPAM.
Identity: why the SH suffix changes the target
The SH suffix is part of the identity, not a decoration. SH, SSH and the bare FO 4240 occupy different positions, and dropping or substituting a suffix changes which product is being discussed.
FO 4240 SH is a distinct entry inside the FO 4000 SH & SHU table, and within that table it is positioned at High molecular weight. The bare FO 4240 sits at Standard molecular weight. Those are different chain-length targets, so an SH requirement answered from the bare-grade position moves in the wrong direction before the trial even starts.
Use the suffix exactly as printed on the bag. Compare the bare grade under FLOPAM FO 4240, which expressly excludes SH and SSH; compare SSH under FLOPAM FO 4000 SSH. ChinaPAM keeps the three designations separate so the quoted route follows the correct chain-length target.
Three facts the held source actually establishes
All three come from page 7 of the 2007 catalogue. The first fixes the position; the second and third are historical figures about the incumbent product.
| Fact | Where it comes from | What it does not establish |
|---|---|---|
| FO 4240 SH is a distinct entry inside the FO 4000 SH & SHU table, classified as a Low charge / High molecular weight cationic powder. | SNF Catalogue 2007 Poudres, page 7, FO 4000 SH & SHU table. | Relative position only. No charge percentage, no molecular weight figure, and nothing transferable to the bare FO 4240 or to SSH. |
| Bulk density 0.85, with Brookfield viscosity 415, 180 and 70 cps at 5.0, 2.5 and 1.0 g/L respectively. | SNF Catalogue 2007 Poudres, page 7. | Historical indicative values from 2007. Not a current competitor specification, not a ChinaPAM specification, and not a performance figure on any sludge. |
| Preparation at 4 g/L recommended and 10 g/L maximum; 90 minutes dissolution in deionized water at 5 g/L and 25 °C; one-day solution stability; 0–35 °C storage; 24-month shelf life, conditional on a footnote requiring stable indoor storage at 5–30 °C; 25 kg bags and 750 kg big bags. | SNF Catalogue 2007 Poudres, page 7. | Handling practice for the incumbent product as published in 2007. Not a ChinaPAM preparation instruction, and the shelf-life figure is meaningless without its storage condition. |
Process conditions and the targets that define a pass
Useful intake: the incumbent grade with its full suffix as printed on the bag; the machine and its shear regime; sludge type and origin; feed solids; pH and temperature; polymer make-up equipment as installed; the make-down water you will actually use, with its hardness, chloride and temperature, since dissolution behaviour follows the water and not the bag; current active dose; the trial quantity and the likely purchase quantity; the destination port or plant; and the cake dryness or filtrate target you are measured against.
Both axes matter here. A low-charge requirement answered at the wrong chain length will dose differently and floc differently even if the charge band is right, and the reverse is equally true. Because neither route holds both axes, the trial is designed to expose each route’s own gap rather than to confirm a guess.
Packaging and minimum order quantity are confirmed with the quotation against grade, destination and order conditions. The 25 kg bag and 750 kg big bag figures that appear on this page belong to the 2007 competitor catalogue and are reproduced as incumbent context only; no ChinaPAM packaging size, order minimum or lead time is asserted here.
Acceptance targets are agreed before the trial: cake dryness, filtrate or centrate quality, throughput, active dose and handling behaviour at a make-up concentration your plant can actually run.
Preparation: the ChinaPAM window, and the incumbent figures for context
ChinaPAM powder preparation runs at a 1–3 g/L recommended window, 5 g/L maximum, and no longer than 60 minutes at working concentration. Preparation concentration is not process dosage.
For reference only, the 2007 catalogue published 4 g/L as the recommended preparation concentration for the incumbent product, 10 g/L as the maximum, and 90 minutes dissolution in deionized water at 5 g/L and 25 °C, with one-day solution stability. The figures quoted from the 2007 catalogue are historical and indicative. They are reproduced here as context for an incumbent product, not as a current competitor specification and not as a ChinaPAM specification. They are shown here because an operator changing over needs to know how the two handling regimes differ, not because either set of numbers transfers to the other product.
The practical consequence is that the make-up concentration a plant is used to running may sit above the ChinaPAM window. That is checked before the trial is scheduled, since make-up concentration drives hydration and therefore the delivered active dose.
Two failure modes that decide this changeover
The first is an identity error, the second is inherent to a two-axis bracket. Neither comes from the polymer itself, and both are cheap to rule out before any bulk commitment.
| Trigger | Consequence | Verification step |
|---|---|---|
| An FO 4240 SH requirement is mistaken for bare FO 4240, whose archived source position is Standard molecular weight. | The chain-length target moves in the wrong direction: floc size and strength differ from the incumbent, dose response shifts, and the trial tests the wrong position. | Confirm the suffix exactly as printed on the bag before quoting. Treat FO 4240 SH, bare FO 4240 and FO 4000 SSH as separate product identities; never substitute one designation for another to force a match. |
| One route is trialled, it passes on the axis it holds, and that result is read as covering the axis it does not hold — a C8008 pass on charge demand treated as settling chain length, or a C8003 pass on floc build treated as settling charge. | The route is committed to bulk with its known gap untested. C8008 at Medium molecular weight can build a weaker floc than the High molecular weight incumbent under the same shear, while C8003 at High charge can overdose and restabilise a low-charge-demand sludge. Either way the plant discovers the gap after changeover, not during the trial. | Design the trial around the gap rather than the strength. For C8008, record floc strength after the machine’s own shear and cake dryness at matched active dose, not just the dose at which floc first forms. For C8003, run the dose ladder down past the expected optimum and watch for restabilisation and filtrate deterioration. Keep the two routes as separate trials with separate results, and do not carry a result from one across to the other. |
Validation, boundary and how to start
Run the comparison on the same sludge, the same machine and the same time window, normalised to active polymer rather than solution volume, across a dose ladder instead of a single point. Record cake dryness, filtrate or centrate quality, floc strength under the shear the machine applies, throughput and the full dose response. If neither CNfloc C8008 nor C8003 passes, the correct next step is to reopen the charge-band and molecular-weight decision rather than to declare an equivalence.
What stands behind the quotation is ChinaPAM’s own position, not a competitor catalogue: see the supplier profile and the certifications and compliance page. Applicable document set and TDS availability are confirmed against the quoted ChinaPAM grade; a batch-specific COA is tied to a confirmed shipment only. Price and sample arrangements are open for discussion now; current competitor specification, competitor stock and ChinaPAM lead time stay unclaimed until separately confirmed.

Brand Equivalents & Replacements
The archived SNF table lists FO 4240 SH as a Low-charge, High-molecular-weight cationic powder, and no single ChinaPAM grade sits in both of those bands. ChinaPAM therefore offers two selection routes with an acknowledged gap in each: CNfloc C8008 holds the Low charge band but is Medium molecular weight, and CNfloc C8003 holds the High molecular weight band but is High charge. ChinaPAM accepts the enquiry, screens on the held document and your stated sludge and equipment conditions, quotes, and discusses sample arrangements from there. Which gap your duty tolerates is decided by a trial on your own feed — neither route is a tested replacement and neither is claimed to match both axes.
| Brand | Grade | Notes |
|---|---|---|
| SNF FLOPAM | FO 4240 SH | Distinct entry inside the FO 4000 SH & SHU table of the 2007 powder catalogue, classified as a low-charge, high-molecular-weight cationic powder. No ChinaPAM grade occupies both bands, so the answer is a bracket: CNfloc C8008 holds the Low charge band at Medium molecular weight, CNfloc C8003 holds the High molecular weight band at High charge. Selection service — no identical product, no drop-in claim and no performance guarantee before a trial. |

Frequently Asked Questions — FLOPAM FO 4240 SH Alternative Selection (CNfloc C8008 / C8003)
Can ChinaPAM supply for a FLOPAM FO 4240 SH requirement?
Yes — as a selection service, and as two routes rather than one. CNfloc C8008 leads because it holds the Low charge band, though it sits at Medium molecular weight; CNfloc C8003 is the backup because it holds the High molecular weight band, though it sits at High charge. No ChinaPAM grade holds both bands, so each route carries a stated gap and the trial decides which gap your duty tolerates. Price and samples are open for discussion immediately. An identical product, a drop-in replacement and guaranteed performance before a trial are not claimed.
Can bare FLOPAM FO 4240 be used to identify an FO 4240 SH requirement?
No. The suffix changes the target. FO 4240 SH sits in the FO 4000 SH & SHU table at High molecular weight, while bare FO 4240 sits at Standard molecular weight. ChinaPAM therefore treats bare FO 4240, FO 4240 SH and FO 4000 SSH as distinct designations and confirms the exact suffix before quoting.
Are the 2007 figures your specification?
No. Bulk density 0.85, the Brookfield viscosity readings and the 4 g/L and 10 g/L preparation values all come from a 2007 competitor catalogue. They are historical and indicative, shown as context for an incumbent product. ChinaPAM preparation runs at 1–3 g/L recommended, 5 g/L maximum and under 60 minutes at working concentration.
Is the 24-month shelf life a straightforward number?
Not on its own. The catalogue attaches a footnote requiring stable indoor storage at 5–30 °C, so the figure only means anything together with that condition. Quoting the 24 months without the storage requirement would misrepresent the source.
Can you match the charge percentage or the molecular weight?
No. Low charge and High molecular weight are relative labels inside one supplier’s own range, and they cannot be converted into a percentage, a molecular weight figure or another supplier’s label. The band question is settled by a comparative trial, not by comparing numbers across catalogues.
Is there a ChinaPAM grade that is both low charge and high molecular weight?
Not in the range screened for this requirement. ChinaPAM therefore offers a bracket instead of a match: C8008 holds the Low charge band at Medium molecular weight, while C8003 holds the High molecular weight band at High charge. Quoting both does not create a grade that satisfies both axes, and the two trials remain separate so a pass on one route is never read as covering the other route’s gap.
What packaging and minimum order quantity apply?
Both are confirmed with the quotation, against the grade selected, your destination and your order conditions. The 25 kg bag and 750 kg big bag figures on this page come from the 2007 competitor catalogue and are incumbent context, not a ChinaPAM packaging offer. No order minimum, stock position or lead time is stated here.
What is still unresolved on this page?
An exact charge percentage and molecular weight figure for the branded grade; current competitor specification and stock, since the held document dates from 2007; ChinaPAM trial results on your sludge; and ChinaPAM lead time and batch documents, which are quotation and shipment matters.
