AN 977 SH in the SNF Anionic Powder Range
SNF's 2007 anionic powder catalogue covers grades from Very Low charge through Low, Medium and High up to Very High. AN 977 SH appears in the SH/SHU table (p.36) as the sole Very High charge entry within that six-column table. The p.36 table publishes Brookfield viscosity at two concentrations cited on this page — 1800 cps at 5 g/L and 680 cps at 2.5 g/L; the catalogue table also includes a 1 g/L column (280 cps). Recommended preparation concentration is 3 g/L, maximum 5 g/L, and dissolution time is 60 minutes in deionised water at 5 g/L and 25°C. Storage is stated as 0–35°C with a 24-month shelf life. All values above are SNF published figures, not ChinaPAM parameters. Our current TDS, MSDS, and batch-specific COA are available at quotation.
The Very High charge position is specific to the SH suffix and the p.36 table. AN 977 SD in the SD table (p.37) is also published as Very High charge with Very High molecular weight but is a distinct grade — the suffix is not interchangeable. The two preparation constraints that matter most for AN 977 SH are the 5 g/L ceiling and the 60-minute dissolution time. Exceeding 5 g/L preparation concentration or dosing before full dissolution both increase the risk of incomplete polymer activation and performance shortfall on your specific feed.

AN 977 SH — Very High Charge, Very High MW (SNF p.36)
FLOPAM AN 977 SH is listed in the SNF 2007 anionic powder catalogue SH/SHU table (p.36) as Very High charge with Very High molecular weight. Published Brookfield readings: 1800 cps at 5 g/L, 680 cps at 2.5 g/L, 280 cps at 1 g/L. Recommended make-up concentration 3 g/L, maximum 5 g/L. Dissolution: 60 min in deionised water at 5 g/L, 25°C. AN 977 SD (p.37) is a distinct grade — suffixes are not interchangeable. ChinaPAM screens supply routes for the AN 977 SH duty position. Contact us to confirm applicable grade-level TDS/MSDS and the relevant batch COA.
Dosage Guide
Very-high-charge anionic polymer demand is set by jar or cylinder settling test on the target slurry or water. Prepare at 1–3 g/L and allow dissolution to complete before dosing — at working concentration this takes up to 60 minutes. Use your current AN 977 dose rate as the starting reference.
Frequently Asked Questions — FLOPAM AN 977 SH Equivalent — Very High Charge Anionic PAM Powder
What makes AN 977 SH different from AN 945 or AN 956?
SNF's 2007 anionic powder catalogue lists AN 977 SH at Very High charge density in the SH/SHU table (p.36). AN 945 and AN 956 are listed at High charge in the same table. The charge tier is taken directly from the published catalogue table; we do not infer it from the number.
Do you supply a grade that covers AN 977 SH duty?
Yes. We supply a very-high-charge, very-high-molecular-weight anionic PAM powder that covers the AN 977 SH duty position. Current grade and batch parameters are confirmed at quotation and backed by current TDS, MSDS, and batch-specific COA with every shipment.
What preparation concentration does AN 977 SH require?
SNF's published catalogue values for AN 977 SH are a recommended preparation concentration of 3 g/L and a maximum of 5 g/L. Our recommended range is 1–3 g/L; the maximum is 5 g/L. Exceeding 5 g/L risks incomplete dissolution regardless of mixing time.
How long does dissolution take?
SNF publishes 60 minutes for AN 977 SH in deionised water at 5 g/L and 25°C. Dissolution at working concentration is complete within 60 minutes. Do not dose before dissolution is finished — partly dissolved solution looks ready but performs below specification.
Is your product a copy of AN 977 SH?
No. It is an independently manufactured anionic polyacrylamide positioned against the published AN 977 SH profile. We are not affiliated with SNF and FLOPAM is their trademark. Confirm suitability by test on your own material before switching supply.
