FLOPAM AN 977 SH Equivalent — Very High Charge Anionic PAM Powder
ChinaPAM supplies a very-high-charge, very-high-molecular-weight anionic PAM powder route for FLOPAM AN 977 SH duty. SNF's 2007 anionic powder catalogue places AN 977 SH as the sole Very High charge entry in the FLOPAM anionic powder range. If your bags read a lower number in the same range, the [AN 945 equivalent](/products/brand-equivalents/flopam-an-945-equivalent) or [AN 945 VHM equivalent](/products/brand-equivalents/flopam-an-945-vhm-equivalent) page is the correct starting point.

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 is the sole Very High charge entry in the table. The catalogue publishes Brookfield viscosity at two concentrations — 1800 cps at 5 g/L and 680 cps at 2.5 g/L — along with a recommended preparation concentration of 3 g/L, a maximum of 5 g/L, and a dissolution time of 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 two preparation constraints that matter most are the 5 g/L ceiling and the 60-minute dissolution time. Using a lower-charge route where the duty specifies Very High charge means the product does not sit at the intended position in the range. 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.

| Charge density | Very High / Très Forte | Very high (our scale) |
| Molecular weight | Very High / Très Haut | Very high (our scale) |

| Recommended prep concentration | 3 g/L | 1–3 g/L |
| Maximum prep concentration | 5 g/L | 5 g/L |
| Dissolution time | 60 min (DI water, 5 g/L, 25°C) | ≤60 min at working concentration |
| Storage temperature | 0–35°C | Store in cool, dry conditions away from direct sunlight |
| Shelf life | 24 months (SNF stated conditions) | Confirm on 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 — the sole Very High entry in the range. AN 945 and AN 956 are listed at High charge. 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.
