Published reference data and the ChinaPAM route for SNF FLOPAM AH 912 SD and SHD
FLOPAM and FLOPAM AH 912 are trademarks of SNF SAS. The historical table data on this page comes from SNF Catalogue 2007 Poudres, PDF page 32, with the anionic-powder positioning taken from page 54 of the same document. SNF states these values are average and given as an indication; they do not constitute a specification. They are historical 2007 indicative catalogue data under SNF test conditions, not ChinaPAM specifications and not evidence of current SNF availability or of a known SD/SHD suffix architecture. Our products are separately branded ChinaPAM grades and are not licensed copies.
| Parameter | ChinaPAM Supply Route | SNF FLOPAM AH 912 SD and SHD |
|---|---|---|
| Physical form | Anionic polyacrylamide powder | Polyacrylamide in powder form (SNF 2007 page 32 table heading, both SD and SHD columns) |
| Ion family | Anionic | AH 912 appears in the SNF 2007 page 54 chart MOLECULAR WEIGHT OF ANIONIC POWDERS, which is why this enquiry is screened as low-anionic and not as a strictly nonionic product |
| Exact intents covered | One low-charge anionic powder route answering both exact suffixes, with SD and SHD kept separate | FLOPAM AH 912 SD and FLOPAM AH 912 SHD — two separate exact columns on SNF 2007 page 32 |
| Charge position | CNfloc 1082 is Low charge on the ChinaPAM scale | Very Low charge density on the SNF 2007 scale for both SD and SHD. The SNF Very Low and ChinaPAM Low descriptors are adjacent word bands on two independent supplier scales and cannot be converted numerically or declared equal. |
| Molecular-weight position | CNfloc 1082 is Very High MW on the ChinaPAM scale. CNfloc 1042 is Low MW and therefore sits a long way from the target MW direction. | Very High molecular weight on the SNF 2007 scale for both SD and SHD columns |
| Evidence status matrix | MATCHED = field-level direction only: powder form, anionic family, and both 1082 and the target carrying a Very High MW descriptor on their own two independent scales. It does not mean the formulation, numbers, viscosity or performance are equivalent. CLOSE = one disclosed adjacent word-band screening difference: the SNF Very Low against the ChinaPAM Low charge descriptor for 1082. The two scales carry no numeric calibration, so no claim of numerically close or same-band charge is made. UNKNOWN = the SD and SHD suffix architecture, current SNF availability and specification, and any numeric cross-brand charge, MW or viscosity equivalence. TEST-REQUIRED = both exact intents, SD and SHD, must be verified by same-feed trial; solution viscosity, hydration and make-down, pump delivery, treatment response and dose are all confirmed under actual conditions. The CNfloc 1042 Low-MW against Very-High-MW gap is not treated as CLOSE; it enters only as a test-required conditional comparison when a real make-down or delivery reason exists. | SNF publishes no cross-vendor equivalence status. Page 32 states its values are average, given as an indication, and do not constitute a specification. |
| Historical Brookfield profile at 5.0 / 2.5 / 1.0 g/L | Measured on the quoted ChinaPAM grade at your own working concentration; ChinaPAM does not claim to reproduce these historical curves | AH 912 SD: 80 / 35 / 15 cps. AH 912 SHD: 100 / 45 / 10 cps. Historical indicative values under SNF test conditions. SNF also notes that preparation and dosing equipment can be selected on a viscosity ten times lower. |
| Recommended / maximum make-up | Per the confirmed preparation instructions for the quoted ChinaPAM grade, verified at your working concentration | 5 g/L recommended and 10 g/L maximum for both SD and SHD columns (historical indicative) |
| Dissolution reference | Measured on the quoted ChinaPAM grade under the confirmed preparation instructions, at the buyer's working concentration and mixing condition | 150 minutes in deionised water at 5 g/L and 25°C for both SD and SHD columns; solution stability one day in deionised water (historical indicative) |
| Packaging | ChinaPAM packaging and delivery terms are confirmed in the quotation against the selected grade, destination and order conditions | Historical catalogue rows list 25 kg bags and 750 kg big bags. These are SNF historical source facts and are not a ChinaPAM packaging offer. |
| Documents | Applicable document set and TDS availability are confirmed with the quoted ChinaPAM grade; a batch-specific COA is tied to a confirmed shipment only. | Catalogue data only; SNF states the values are indicative and do not constitute a specification |

What the Source Document Records for AH 912 SD and AH 912 SHD
The traceable record for this enquiry is the SNF Catalogue 2007 Poudres. Two exact columns appear on PDF page 32 — FLOPAM AH 912 SD and FLOPAM AH 912 SHD — and both are read here as separate columns rather than as one shared dataset. Three facts are traceable to that page for both suffixes: each carries a Very Low charge descriptor with a Very High molecular-weight descriptor on the SNF scale; each lists an approximate bulk density of 0.85; and each lists the same make-up and dissolution rows, namely a 5 g/L recommended concentration, a 10 g/L maximum, 150 minutes to dissolve at 5 g/L and 25 °C, and roughly one day of prepared-solution stability. The 25 kg bag and 750 kg big-bag rows are likewise facts of that 2007 document.
The anionic positioning is traceable to a second page of the same document. PDF page 54 carries a chart headed MOLECULAR WEIGHT OF ANIONIC POWDERS, and AH 912 is listed there. That is the published basis for screening this enquiry as a very-low-charge anionic powder rather than as a strictly nonionic product.
The limit on all of it is stated by the source itself. SNF records that the values are average, given as an indication, and do not constitute a specification. They are historical 2007 catalogue figures measured under SNF test conditions on SNF products. They are not ChinaPAM specifications, they are not evidence that any of these grades is currently available from SNF, and they do not disclose what the SD and SHD suffixes mean structurally.

The Concentration-Dependent Profile Difference, and What It Does Not Prove
The two columns are not interchangeable in the source data. Their indicative Brookfield profiles differ, and the order between them reverses as concentration falls. At 5.0 g/L, SHD reads higher than SD, at 100 against 80 cps. At 2.5 g/L, SHD again reads higher, at 45 against 35 cps. At 1.0 g/L the order reverses: SHD reads lower than SD, at 10 against 15 cps. Anyone treating the two suffixes as one dataset would be averaging across a reversal.
What this difference proves is narrow and worth stating plainly. It establishes only that the two exact columns carry different concentration-dependent profiles inside one historical SNF table. It does not reveal a suffix architecture, it does not establish a chemical or structural cause for the difference, and it carries no implication for how any ChinaPAM grade will behave on viscosity. The practical consequence is procedural rather than interpretive: the exact suffix on your label has to be confirmed and carried through, and the make-down concentration at which any comparison is made has to be recorded, because a reading taken at 1.0 g/L ranks these two columns in the opposite order from a reading taken at 5.0 g/L.
SNF adds one further note on the same page that bears directly on engineering decisions: preparation and dosing equipment can be selected on a viscosity ten times lower than the figures shown. Treating the catalogue Brookfield numbers as design values for tank sizing or pump selection is therefore unsound even within the source document, and it is not transferable to a ChinaPAM-sourced product at all.
How ChinaPAM Routes the Enquiry, and the Gap That Stays Open
ChinaPAM supplies and can quote on both intents. The primary screening route for AH 912 SD and for AH 912 SHD is CNfloc 1082, an anionic powder carried at Very High molecular weight and Low charge on the ChinaPAM scale. It holds the ion family and the powder form, and it preserves the Very High molecular-weight direction that both source columns carry.
The gap that stays open is the charge descriptor. The source columns read Very Low; 1082 reads Low. Those are adjacent word bands belonging to two independent supplier scales, and no numeric calibration exists between them. ChinaPAM does not present that as a numeric match, a same-band match or an equivalence, and does not convert one scale into the other. It is a disclosed screening difference, and the same-feed trial is what settles it.
CNfloc 1042 is offered as one conditional comparison only, not as a co-primary route and not as a second equivalent. It is anionic at Low charge but also Low molecular weight, which puts a large molecular-weight-band gap against a Very High MW target. It belongs in the plan only when a lower-molecular-weight-band make-down or solution-delivery constraint gives a real reason for it, and it is handled as test-required rather than close. Nonionic CNfloc 1003 is excluded outright by the ion gate: this enquiry screens as anionic on the page 54 evidence, and routing it to a nonionic grade loses the intended direction.
| Failure mode | What triggers it | Consequence if missed | How to verify before committing |
|---|---|---|---|
| Ion-type misclassification | A contents or navigation grouping is used to classify AH 912 instead of the page 54 anionic-powder chart, and the enquiry is treated as strictly nonionic. | The enquiry is routed to nonionic CNfloc 1003, the intended very-low-anionic screening direction is lost, and the trial tests the wrong ion family. | Lock the complete bag label and ion-family requirement; start with the 1082 low-charge anionic powder route; compare on the buyer's actual feed. |
| Suffix and viscosity-profile collapse | The suffix is read as a bare AH 912 or merged with SH, HD, PWG or SEP, and one viscosity dataset is reused across suffixes. | The wrong dissolution expectation is carried into planning — the bare AH 912 column shows a 90-minute dissolution row against the 150 minutes shown for SD and SHD — and the SD/SHD reversal at 1.0 g/L is averaged away, so make-down time and solution handling are sized from data that does not belong to the grade in hand. | Lock the exact SD or SHD suffix; measure make-down time and viscosity at actual working concentration; verify pump delivery; compare treatment response on the same feed using normalized active-polymer mass. |
Controlled Validation and What to Send to Open a Quotation
A comparison is only worth acting on if it is controlled. Prepare each supplier grade according to its own instructions rather than forcing a single shared procedure, and allow the full dissolution time before sampling, since an under-hydrated solution will understate a grade regardless of which supplier made it. Normalise the dose on active-polymer mass rather than on as-supplied product mass, so the two routes are genuinely compared at the same dose basis. Then run them on the same feed within the same time window and compare four things: treatment response against your target, hydration and make-down behaviour, solution viscosity at the intended working concentration, and pump delivery at that viscosity. The route that holds your target at the lowest stable dose under those conditions is the one the quotation is fixed against. Before any bulk changeover, the working grade and dose are set on your actual feed and equipment.
To open a quotation, the exact SD or SHD suffix — or a photo of the bag label — is enough to start. Four further inputs let ChinaPAM aim the route rather than guess at it: your make-down concentration and mixing time together with the solution-handling equipment in use, since the SD/SHD reversal makes the concentration a material input; your current active dose and the product it is measured on; your feed description, treatment target and the duty the polymer is doing; and your volume, packaging preference and destination.
Sample arrangements, the applicable document set, ChinaPAM packaging and delivery time are confirmed in the quotation against the selected grade, destination and order conditions. Applicable document set and TDS availability are confirmed with the quoted ChinaPAM grade; a batch-specific COA is tied to a confirmed shipment only. Nothing on this page is a free-sample promise, a price quotation or a guarantee of a specific result on your feed.
Frequently Asked Questions — FLOPAM AH 912 SD / SHD Equivalent Screening
Can ChinaPAM supply for a FLOPAM AH 912 SD or AH 912 SHD requirement?
Yes. ChinaPAM supplies and can quote a low-charge anionic polyacrylamide powder screening route for both exact suffixes. CNfloc 1082 is the primary starting grade for AH 912 SD and for AH 912 SHD alike. Send the exact suffix as printed on your bag label, TDS or purchase order — or a photo of the label — together with your make-down concentration and time, solution-handling equipment, current active dose, feed description, target, volume and destination. The exact suffix or label photo alone is enough to open the enquiry; the remaining inputs sharpen the route and the sample test plan.
Why is CNfloc 1082 the primary route, and what gap remains?
CNfloc 1082 is an anionic powder carried at Very High molecular weight and Low charge on the ChinaPAM scale. It holds the same ion family and powder form as the target and preserves the Very High MW direction that both the SD and SHD columns carry on the SNF 2007 scale. The gap that remains is the charge descriptor: the SNF 2007 columns read Very Low, while 1082 reads Low on the ChinaPAM scale. Those are adjacent word bands on two independent supplier scales with no numeric calibration between them, so ChinaPAM does not present them as numerically close, same-band or equivalent. The gap is a disclosed screening difference that your same-feed trial has to settle.
When is CNfloc 1042 used, and is it a second equivalent?
No, 1042 is not a second equivalent and it is not co-primary with 1082. CNfloc 1042 is an anionic powder at Low charge and Low molecular weight. It keeps the low-charge anionic direction but introduces a large molecular-weight-band gap against a Very High MW target. ChinaPAM offers it only as one conditional comparison, and only when you have a real reason tied to a lower-molecular-weight-band make-down or solution-delivery constraint. Because the MW separation is large, that comparison is handled as test-required, not as a close match.
Do AH 912 SD and AH 912 SHD behave the same way in the historical data?
No. On SNF 2007 page 32 the two exact columns carry the same charge and molecular-weight labels, the same approximate bulk density of 0.85, the same 5 g/L recommended and 10 g/L maximum concentrations and the same 150-minute dissolution row, but their indicative Brookfield profiles differ and the order between them reverses with concentration. SHD reads higher than SD at 5.0 g/L, at 100 against 80 cps, and at 2.5 g/L, at 45 against 35 cps. At 1.0 g/L the order reverses and SHD reads lower than SD, at 10 against 15 cps. That difference is a fact of the historical SNF table only. It does not reveal what the suffixes mean structurally, it does not establish a chemical cause, and it says nothing about how a ChinaPAM grade will behave on viscosity.
Is AH 912 a nonionic product?
Treating it as strictly nonionic is a routing error on this enquiry. AH 912 appears in the SNF 2007 page 54 chart headed MOLECULAR WEIGHT OF ANIONIC POWDERS, which supports screening it as a very-low-anionic powder family. If treated as strictly nonionic, the enquiry can be routed to nonionic CNfloc 1003 and lose the intended low-anionic screening direction. Lock the complete bag label and the ion-family requirement first, then start from the 1082 low-charge anionic powder route.
Can the historical SNF Brookfield figures be used to size make-down tanks and dosing pumps?
Not for a ChinaPAM-sourced product. SNF page 32 states that its values are average, given as an indication, and do not constitute a specification, and it separately notes that preparation and dosing equipment can be selected on a viscosity ten times lower. Those figures were measured under SNF test conditions on SNF products in 2007. ChinaPAM makes no claim to reproduce them. Measure make-down time and solution viscosity on the selected ChinaPAM grade at your actual working concentration, and verify pump delivery before equipment is fixed.
How should the two routes be validated on my feed?
Prepare each supplier grade according to its own instructions rather than forcing a shared procedure, and allow the full dissolution time before sampling. Normalise the comparison on active-polymer mass, not on as-supplied product mass, so the dose basis is genuinely equal. Then compare on the same feed, in the same time window: treatment response, hydration and make-down behaviour, solution viscosity at the intended working concentration, and pump delivery. The route that meets your target at the lowest stable dose under those controlled conditions is the one to fix the quotation on.
What samples, packaging and documents apply?
Current sample arrangements, ChinaPAM packaging and delivery, and the applicable document set are all confirmed at quotation stage against the selected grade, destination and order conditions. A batch-specific COA is tied to a confirmed shipment only. The 25 kg bag and 750 kg big-bag rows that appear in the historical SNF catalogue are source facts about that 2007 document and are not a ChinaPAM packaging offer.
My label says AH 912 SH, or has no suffix at all. Is this the right page?
No. This page owns the FLOPAM AH 912 SD and FLOPAM AH 912 SHD intents only. AH 912 SH is a separate exact column with its own screening page, and the bare AH 912 and AH 912 HD columns differ again — the bare column carries a 90-minute dissolution row rather than the 150-minute row shown here. AH 912 PWG and AH 912 SEP are covered by a different owner page. Reusing data across those suffixes is exactly the collapse this page is built to prevent, so confirm the complete suffix on the label before selecting a route.
