AN 900 SD Grade Selector: Nine Exact Grades, Four ChinaPAM Lanes
Find the exact grade on your bag label or purchase record, then start from the ChinaPAM lane on the same row. The lanes are directional screening routes, not cross-brand equivalence: ChinaPAM and SNF charge and molecular-weight words are each supplier’s own qualitative bands and do not convert numerically. The choice closes through a jar test on your actual feed and a viscosity check at the same concentration.

SD Is Not VHM: Why the Suffix Changes the Equipment Plan
In the same 2007 catalogue SNF places the nine SD grades in a separate p.37 table headed anionic powder of very high molecular weight and very low viscosity, while the p.34 VHM table is headed ultra high molecular weight. “Very low viscosity” is SNF’s table heading; this page does not define the SD suffix beyond that.
The practical difference shows in the dissolution reference. All nine SD columns list 60 minutes at 5 g/L in deionised water at 25°C. The corresponding VHM columns list 150 minutes for AN 905 VHM and 90 minutes for AN 910 VHM through AN 956 VHM. The p.34 table has no AN 970 or AN 977 VHM column, so no VHM comparison is made for those two grades.
| Grade number | SD dissolution | VHM dissolution | Planning consequence |
|---|---|---|---|
| AN 905 | 60 min | 150 min | Confirm the suffix before sizing maturation tanks |
| AN 910 / 913 / 923 / 934 / 945 / 956 | 60 min | 90 min | Do not carry VHM maturation or viscosity assumptions into an SD enquiry |
| AN 970 / AN 977 | 60 min | No VHM column on p.34 | Compare only against the exact SD column |
Three Model Facts Buyers Can Trace
First, identity: SNF 2007 puts the nine exact AN 900 SD grades in their own p.37 table described as anionic powder of very high molecular weight and very low viscosity, while the p.34 VHM table says ultra high molecular weight. An SD enquiry is its own purchasing line, not a spelling of VHM.
Second, dissolution: all nine SD columns list 60 minutes at 5 g/L in deionised water at 25°C, against 150 minutes for AN 905 VHM and 90 minutes for AN 910 VHM through AN 956 VHM under the same catalogue conditions.
Third, the High-charge SD grades are not interchangeable by viscosity. AN 945 SD, AN 956 SD and AN 970 SD share the High charge label but list 1.0 g/L indicative viscosities of 200, 220 and 110 cps respectively.
Two Failure Modes Worth Checking Before Bulk Supply
Both risks come from treating a label as more precise than it is. Each has a visible symptom and a direct check.
| Failure mode | Trigger | Symptom | Check |
|---|---|---|---|
| SD and VHM suffix mix-up during equipment or make-up planning | The suffix is dropped and VHM viscosity or dissolution assumptions are reused for an SD enquiry | Measured solution viscosity, maturation time or pump pressure does not match the chosen equipment setting | Confirm the full bag-label suffix, then measure dissolution time and solution viscosity at the actual working concentration before equipment settings are fixed |
| High-charge SD grades treated as interchangeable | AN 945 SD, AN 956 SD and AN 970 SD are selected only from the shared High charge label | Unexpected pump pressure, dilution behaviour or process response | Run same-feed jar tests and measure viscosity at the same concentration for the exact shortlisted grade |
Actual-Feed Jar Test and Viscosity Verification Plan
Use your current SD grade as the baseline. Take one representative feed sample, prepare the incumbent and the shortlisted ChinaPAM grades at the same working concentration, and let each hydrate fully. Record dissolution time and solution viscosity for each before dosing.
Run stepped doses on the same feed with the same mixing energy, solution age and observation time. Record settling rate, supernatant clarity and the point where more dose stops helping. The lowest stable dose that meets your target decides the grade; equipment settings are fixed only after the viscosity check matches.
What to Send for a Quotation
The exact grade and quantity are enough to start pricing. These details make the sample plan sharper:
| Input | Why it matters |
|---|---|
| Full model and suffix, or a bag-label photo | Separates SD from bare, SH, VHM and VLM grades |
| Application and feed | Decides which lane is screened first |
| Working concentration and make-up equipment | Sets the viscosity and dissolution check conditions |
| Target result | Settling rate, clarity, cake or underflow goal for the trial |
| Current dose | Baseline for the stepped comparison |
| Expected volume and destination | Pricing, packaging and lead time in the quotation |
Documents and Delivery
The applicable TDS is confirmed together with the selected ChinaPAM grade. A batch COA is tied to the confirmed shipment. Packaging and lead time are confirmed in the quotation for your volume and destination.
Dosage Guide
Use the current AN 900 SD active dose as the first reference point. Prepare the shortlisted ChinaPAM powder at the same working concentration as the incumbent, allow full hydration, and run a stepped side-by-side test on the same feed. Fix the dose and equipment settings only after the viscosity check matches.
Frequently Asked Questions — FLOPAM AN 900 SD Series Equivalent — Anionic PAM Powder Supply for AN 905 SD to AN 977 SD
Can ChinaPAM supply for a FLOPAM AN 900 SD requirement?
Yes. ChinaPAM supplies anionic polyacrylamide powder for AN 900 SD series enquiries. Send the exact SD grade, quantity and destination and we will name the screening lane, quote current pricing and arrange a sample test plan.
Which ChinaPAM grade do I start with for my SD grade?
AN 905/910/913 SD start in the CNfloc 1042 and 1082 lane; AN 923/934 SD in the CNfloc 1062 and 1063 lane, with K62 as an application-dependent option; AN 945/956/970 SD in the CNfloc 1054, 1054V and 1054VK lane; AN 977 SD in the 635B, 635A and 1001-ZJ lane. The jar test on your feed selects the final grade.
Is AN 934 SD the same as AN 934 VHM or AN 934 SH?
No. SNF lists SD, VHM and SH grades in separate tables. In the 2007 catalogue the SD columns list 60 minutes dissolution where the corresponding VHM columns list 90 minutes (150 for AN 905 VHM). Quote and test against the full suffix.
Can AN 945 SD, AN 956 SD and AN 970 SD be swapped?
Not on the charge label alone. All three are High charge in SNF’s table, but their 1.0 g/L indicative viscosities are 200, 220 and 110 cps. Measure viscosity at the same concentration and run same-feed jar tests for the exact grade.
Which documents come with the supply?
The TDS for the selected ChinaPAM grade is confirmed with the grade, and a batch COA is tied to the confirmed shipment. Packaging and lead time are set in the quotation.
