What SNF Publishes for AN 945 SH
The figures below are reproduced from the SNF SAS powder catalogue, Catalogue 2007 Poudres, covering the FLOPAM AN 900 SH & SHU range printed across pages 35–36. The catalogue prints its own caveat: the data are given for information only and do not constitute a specification.
AN 945 SH carries high charge density at very high molecular weight in the SH series. SNF publishes Brookfield readings of approximately 1820 cps at 5.0 g/l, 700 cps at 2.5 g/l, and 280 cps at 1.0 g/l (approximate values, SNF Catalogue 2007 Poudres p.36). Recommended make-up concentration is 3 g/l; maximum is 5 g/l; dissolution time is 60 minutes in deionized water at 5 g/L and 25°C.
The SHU variant AN 945 SHU, also on page 36, publishes 1500/900/400 cps at 5/2.5/1 g/l. Against the SH row the ordering changes with concentration: at 5.0 g/l SH is higher (1820 vs 1500), while at 2.5 g/l and 1.0 g/l SHU is higher (900 vs 700, and 400 vs 280). Those are the reference values the catalogue prints at three concentrations, not a field result. Check which suffix your specification names, and compare the candidate supply against your incumbent on your own water at the make-up concentration you intend to run.
The VHM variant AN 945 VHM is a separate product at ultra high molecular weight with a published 90-minute dissolution time. Its MW designation and dissolution requirement are not transferable to AN 945 SH.
Our Supply Route and Selection Logic
Our 1054V grade sits at Very High MW and High charge on our own internal scale. SNF describes AN 945 SH as High charge and Very High MW on its own scale (Catalogue 2007 Poudres p.36). The descriptors read alike, but each manufacturer sets its own band boundaries, so matching wording is not a numeric equivalence between the two products. Contact us to discuss pricing, sample arrangements and applicable product documents for the supply grade, and compare them against the SNF reference figures at the make-up concentration you intend to run.
The practical decision point is: does your specification call for SH, SHU, or VHM? Each is a distinct grade in the SNF catalogue with its own published viscosity row. The SH series is the correct starting point when the purchase order reads SH. Note that SNF publishes 3 g/l recommended and 5 g/l maximum for AN 945 SH, while our supply grade is prepared at 1–3 g/L with a 5 g/L maximum — check your actual working concentration against both. For the standard AN 945 grade, see the AN 945 equivalent page. For AN 945 VHM, see the AN 945 VHM equivalent page — that grade is at ultra high MW with a 90-minute dissolution requirement.
Dosage Guide
SNF publishes AN 945 SH at 3 g/l recommended and 5 g/l maximum make-up concentration, with 60 minutes dissolution at 5 g/l and 25°C (Catalogue 2007 Poudres, page 36). Our preparation parameters for the supply grade are 1–3 g/L recommended and max 5 g/L, dissolution ≤60 min at working concentration. Establish the effective dose on your water by jar test before operating at volume.
Frequently Asked Questions — FLOPAM AN 945 SH Equivalent — High Charge Very High MW Anionic PAM
Do you have a supply route for FLOPAM AN 945 SH duty?
Yes. ChinaPAM supplies a high-charge, very-high-molecular-weight anionic PAM powder route for AN 945 SH duty. Contact us to discuss pricing, sample arrangements and applicable product documents.
What is the difference between FLOPAM AN 945 SH, SHU, and VHM?
All three carry high charge density. AN 945 SH (Catalogue 2007 p.36) publishes Brookfield 1820/700/280 cps at 5/2.5/1 g/l and 60-minute dissolution in deionized water at 5 g/L and 25°C. AN 945 SHU (p.36) publishes 1500/900/400 cps at the same three concentrations — lower than SH at 5.0 g/l, higher at 2.5 g/l and 1.0 g/l. SH and SHU are both described as Very High MW; AN 945 VHM is described as Ultra High MW and publishes a 90-minute dissolution time. These are distinct grades. Check the full suffix on your bags and purchase order before selecting a supply route.
What make-up concentration does SNF publish for AN 945 SH?
SNF publishes 3 g/l recommended and 5 g/l maximum for AN 945 SH (Catalogue 2007 Poudres, page 36). Our preparation parameters for the supply grade are 1–3 g/L recommended and max 5 g/L.
How do I verify whether an alternative anionic PAM supply works for my process?
Prepare polymer solution at 1–3 g/L and run a jar test or settling test on your actual feed water at several dose rates, comparing settling rate and supernatant clarity against your current AN 945 SH supply. Contact us to discuss pricing, sample arrangements and applicable product documents.
Does this page apply if my bags say AN 945 VHM?
No. AN 945 VHM is at ultra high molecular weight with a 90-minute dissolution time and a different viscosity profile. This page covers the AN 945 SH suffix only. For the standard AN 945 equivalent, see the AN 945 equivalent page. For AN 945 VHM, see the AN 945 VHM equivalent page.
