FLOPAM and FLOPAM AN 900 SHD are trademarks of SNF SAS. The historical table data on this page comes from SNF Catalogue 2007 Poudres, PDF page 38. SNF states these values are average and indicative; they do not constitute a specification. They are historical 2007 catalogue figures under SNF test conditions, not ChinaPAM specifications and not evidence of current SNF availability. Our products are separately branded ChinaPAM grades and are not licensed copies.
| Parameter | ChinaPAM Supply Route | SNF FLOPAM AN 900 SHD series |
|---|---|---|
| Physical form | Anionic polyacrylamide powder | Anionic powder, very high molecular weight and ultra-low viscosity (SNF 2007 table heading) |
| Grades covered | Four ChinaPAM anionic powder routes covering all nine SHD enquiries | AN 905 / 910 / 913 / 923 / 934 / 945 / 956 / 970 / 977 SHD |
| Charge sequence | AN 910/913, AN 945/956/970 and AN 977 only share a same-named charge/MW descriptor on two independent qualitative scales. AN 905 carries one charge-band gap. For AN 923/934, K62 and 1054V each hold one dimension and differ on the other. All nine require a same-feed test. | Very Low, Low, Low, Medium, Medium, High, High, High, Very High across the nine columns (SNF 2007 scale) |
| Evidence status matrix | MATCHED = same-named descriptor alignment on two independent scales only, not equivalence (AN 910/913, AN 945/956/970, AN 977). CLOSE = the disclosed single-dimension difference routes for AN 905 and AN 923/934. UNKNOWN = cross-brand numeric equivalence and whether the ultra-low-viscosity architecture is shared. TEST-REQUIRED = all nine grades, by same-feed test. | SNF publishes no cross-vendor equivalence status; catalogue values are stated as average and indicative only |
| Molecular-weight position | 1082, 1054V and 635B are Very High MW on the ChinaPAM scale; K62 is High MW and preserves Medium charge for the primary AN 923/934 SHD route. | Very High on the SNF 2007 scale for all nine SHD columns |
| Viscosity architecture | ChinaPAM does not claim to share the historical SHD ultra-low-viscosity architecture | Ultra-low viscosity family label per SNF 2007 table heading |
| Dissolution reference | Measured on the quoted ChinaPAM grade at your working concentration | 60 min at 5 g/L, deionised water, 25°C (all nine columns, SNF historical data) |
| Recommended / maximum make-up | Per the TDS of the selected ChinaPAM grade | AN 905 / 910 SHD: 5 / 10 g/L; AN 913 / 923 / 934 SHD: 3 / 5 g/L; AN 945 / 956 / 970 / 977 SHD: 3 / 5 g/L (historical indicative) |
| Documents | TDS for the selected ChinaPAM grade; COA tied to the confirmed shipment | Catalogue data; SNF states values are indicative and do not constitute a specification |

Read the exact grade from your bag label or purchase order. The SHD suffix is its own SNF table on page 38 of the 2007 catalogue, headed anionic polyacrylamides in powder form of very high molecular weight and ultra low viscosity. It is not the same table as the bare AN 900, SD, HD, SH, MPM/MPMU, VHM or VHMU grades. A procurement line that names FLOPAM AN 934 SHD is a different purchasing line from FLOPAM AN 934 or FLOPAM AN 934 SD.
The table below gives the three traceable facts from the SNF 2007 source alongside the ChinaPAM starting route for each exact SHD grade. Routes are directional screening starts based on qualitative band alignment, not a claim of cross-brand equivalence. ChinaPAM and SNF each use their own charge and molecular-weight scales, and the two do not convert numerically.
| Exact SNF grade | SNF charge (2007) | Historical Brookfield cps at 5 / 2.5 / 1 g/L | SNF rec. / max. g/L | ChinaPAM route | Commercial state |
|---|---|---|---|---|---|
| AN 905 SHD | Very Low | 200 / 60 / 30 | 5 / 10 | CNfloc 1082 (Low charge / Very High MW) | SELECTION_SERVICE — one-band charge gap: ChinaPAM 1082 is Low, not Very Low |
| AN 910 SHD | Low | 250 / 100 / 40 | 5 / 10 | CNfloc 1082 (Low charge / Very High MW) | SAME_TYPE_SCREENING |
| AN 913 SHD | Low | 350 / 150 / 60 | 3 / 5 | CNfloc 1082 (Low charge / Very High MW) | SAME_TYPE_SCREENING |
| AN 923 SHD | Medium | 400 / 180 / 80 | 3 / 5 | CNfloc K62 primary; 1054V conditional if same-feed test clearly favours it | SAME_TYPE_SCREENING |
| AN 934 SHD | Medium | 500 / 250 / 100 | 3 / 5 | CNfloc K62 primary; 1054V conditional if same-feed test clearly favours it | SAME_TYPE_SCREENING |
| AN 945 SHD | High | 500 / 250 / 100 | 3 / 5 | CNfloc 1054V (High charge / Very High MW) | SAME_TYPE_SCREENING |

Three SHD Facts Buyers Can Trace to the SNF 2007 Source
First, identity: the SNF 2007 catalogue lists nine exact SHD identities — AN 905 SHD through AN 977 SHD — and labels all nine as anionic powder of very high molecular weight on the historical SNF scale. The table heading adds the family descriptor ultra low viscosity, which belongs to the SNF product description and is not a ChinaPAM specification.
Second, charge sequence: the historical charge labels run Very Low, Low, Low, Medium, Medium, High, High, High, Very High across the nine exact SHD columns in that order. This is the sequence from the SNF 2007 source. It is not a ChinaPAM charge scale and the two scales do not convert numerically.
Third, preparation: the SNF 2007 table publishes model-specific indicative Brookfield values and different recommended preparation concentrations. AN 905 SHD and AN 910 SHD carry a 5 g/L recommended concentration; AN 913 SHD through AN 977 SHD carry a 3 g/L recommended concentration. All nine share the same historical dissolution row: 60 minutes in deionised water at 5 g/L and 25°C. These figures are SNF historical indicative data. Do not copy them into ChinaPAM equipment designs without measuring the selected ChinaPAM grade at your own working concentration.
Two Failure Modes to Check Before Bulk Supply
Both originate from reading the suffix off the procurement line.
| Failure mode | Trigger | Consequence | Check |
|---|---|---|---|
| Suffix dropped or merged | The SHD suffix is omitted or merged with a bare AN 900, SH, SD or VHM procurement record | The buyer uses the wrong charge, MW, viscosity or preparation table for the procurement | Lock the complete bag-label and TDS identity including the SHD suffix before selecting a ChinaPAM screening route |
| Historical SNF data treated as ChinaPAM specification | Historical SNF Brookfield values or the 'ultra low viscosity' family label are copied into equipment design as a ChinaPAM specification | Make-down tanks and dosing pumps can be sized from an unsupported cross-vendor assumption, causing over- or under-preparation | Keep the SNF values source-labelled and indicative; verify the selected ChinaPAM batch with current documents, make-down observation and same-feed trial |
How to Validate the Selected ChinaPAM Route on Your Feed
Prepare each ChinaPAM candidate at its TDS-recommended concentration, not at the historical SNF recommended concentration. Allow the full dissolution time before sampling. Run equal-active-dose cylinder or jar tests against the current product on the same feed, in the same time window.
Compare initial settling rate, supernatant clarity at the same time point, compacted-bed height after 30 minutes, and floc integrity under gentle shear. The route that meets or approaches the incumbent on those four metrics at the lowest stable dose is the one to fix the quotation on.
For AN 905 SHD enquiries, the same-feed test must also evaluate whether the one-band charge gap (Low vs Very Low) matters on your specific feed. Some feeds are insensitive to a single charge-band step; others are not. The test, not the band comparison, decides.
For AN 923 SHD and AN 934 SHD, run both K62 and 1054V in the same test batch. If clarity and settling rate are equivalent, K62 is the primary supply route. If 1054V scores clearly better on both, that result supports selecting 1054V despite its one-band charge increase; the test on its own cannot establish that chain length is the cause.
What to Send to Open a Quotation
The exact grade name with the SHD suffix as it appears on your current bag label, TDS or purchase order. The present dose basis (g/t or mg/L). The make-down concentration and mixing time you currently use. A brief description of the feed: industry, process stage, solids loading, and pH if known. The equipment type: thickener, centrifuge, belt press, clarifier or other. The target: settling rate, clarity, cake dryness or other.
The exact label alone is enough to start. The other inputs allow ChinaPAM to confirm the route and prepare a sample test plan that matches your operating conditions.
Frequently Asked Questions — FLOPAM AN 900 SHD Equivalent Screening
Can ChinaPAM supply for a FLOPAM AN 900 SHD requirement?
Yes. ChinaPAM supplies and can quote anionic PAM powder screening routes for all nine AN 900 SHD procurement enquiries. Send the exact SHD grade name as it appears on your label or purchase order, together with the present dose basis, make-down condition and separation target, and we will open a quotation and arrange a sample test plan.
What is the charge-band gap for AN 905 SHD, and why does it matter?
AN 905 SHD carries a Very Low charge on the SNF 2007 scale. ChinaPAM 1082 sits at Low charge on the ChinaPAM scale — one band higher. That gap means 1082 cannot be presented as a direct same-band match. ChinaPAM routes AN 905 SHD enquiries through 1082 as a SELECTION_SERVICE: the polymers share Very High MW and anionic powder form, but the one-band charge difference must be evaluated on your feed before supply is fixed. The other eight SHD grades do not carry the specific AN 905 Very-Low-to-Low charge gap, while AN 923/934 SHD carry their own separately stated K62-versus-1054V route trade-off between charge and MW.
Why are K62 and 1054V both listed for AN 923 SHD and AN 934 SHD?
Both SHD grades sit at Medium charge and Very High MW on the SNF 2007 scale. K62 is High MW / Medium charge on the ChinaPAM scale — it preserves charge but is one MW band lower. 1054V is Very High MW / High charge — it preserves chain length but is one charge band higher. Which route fits your feed is decided by the same-feed test result, not by reading the bands. Start with K62; run 1054V alongside it, and if 1054V scores clearly better, that supports selecting 1054V despite its one-band charge increase. The test alone does not establish which property caused the difference.
Is 635B confirmed as better than 635A for AN 977 SHD?
No. 635B is the operational first-screen route for AN 977 SHD enquiries. 635A is a same-band internal alternative: both are Very High MW and Very High charge on the ChinaPAM scale. ChinaPAM does not claim that 635B is evidence-proven superior to 635A. The two are not co-primary — 635B is the starting choice for this enquiry, and 635A is available if the same-feed test supports it.
What inputs does ChinaPAM need to start a quotation?
The exact grade name with the SHD suffix as printed on your label or TDS, together with your present dose basis, make-down concentration and time, feed description, equipment type and separation target. Exact label alone is enough to open the enquiry; the other inputs sharpen the route selection and sample test plan.
Why can the historical SNF Brookfield values not be used for ChinaPAM equipment sizing?
The SNF 2007 catalogue states that all values are average and indicative and do not constitute a specification. They were measured under SNF test conditions for SNF products. ChinaPAM does not claim that its grades share the historical SHD ultra-low-viscosity architecture. Using these historical figures to size make-down tanks or dosing pumps for a ChinaPAM-sourced product can produce an equipment error. Use the TDS of the selected ChinaPAM grade and verify viscosity at your working concentration.
What documents come with the supply?
Applicable documents, sample arrangements, packaging and lead time 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.
