What the SNF 2007 Catalogue Publishes for the FO 4490 Family
The SNF 2007 cationic powder catalogue lists FLOPAM FO 4490 at Medium charge and Standard MW. It lists FO 4490 SH and FO 4490 SHU at Medium charge and High MW. It lists FO 4490 SSH separately at High charge and Very High MW.
The suffix is therefore not cosmetic. It changes both the molecular weight band and, in the SSH case, the charge band as well. The catalogue is dated 2007 and we cite it as a historical indicative source only; it is not current SNF specification or availability.
| Variant | Charge (catalogue) | Molecular weight (catalogue) | ChinaPAM lane |
|---|---|---|---|
| FO 4490 (root) | Medium | Standard | C8001 / C8015 |
| FO 4490 SH / SHU | Medium | High | C8003 / C8035 |
| FO 4490 SSH | High | Very High | C8005 with C8055 / C8006 |
| Source | SNF 2007 catalogue | Historical indicative only | — |
How to Confirm the Suffix Before Ordering
The full bag label or the current TDS is used to confirm the suffix. Photographs of the bag label are the most reliable source because they capture the printed grade string exactly as supplied.
If neither is available, we treat the route as root duty until the suffix is confirmed, and we note that in the quotation. This protects against the most common failure mode — selecting a Standard MW lane for an SSH duty.
The Two Risks to Test on Your Own Sludge
The first risk is suffix collapse: dropping SH, SHU or SSH from the grade string hides the MW and charge differences that the catalogue actually lists. A root-duty route can fail an SSH duty through insufficient chain length or charge.
The second is confirmed only by the same-sludge trial: actual dewatering performance depends on your specific sludge and operating conditions, not on catalogue positions. The bag label confirms which lane to enter; the trial confirms whether it works on your feed.
What We Will and Will Not Claim
ChinaPAM supplies cationic PAM powder. We are not affiliated with, endorsed by, or a distributor for SNF. FLOPAM is a registered trademark of SNF and appears here solely to identify the product a buyer is currently using and looking to evaluate an alternative for.
We do not claim our grades match FO 4490 specification-for-specification, and we do not claim our charge and MW descriptors map directly to the SNF scale. The SNF catalogue positions are historical indicative values from a 2007 document, not current or contractual numeric specifications, and we cite them only to establish the selection direction.
Dosage Guide
Take your current FO 4490 dose as the starting reference, identify the suffix from the bag label or current TDS, then confirm with a jar or CST trial on your actual sludge. Prepare and make up the quoted grade according to the applicable product documents for the ChinaPAM grade quoted.
Frequently Asked Questions — FLOPAM FO 4490 Equivalent — Suffix-Specific Cationic PAM Selection
Why does the suffix matter so much here?
The SNF 2007 powder catalogue lists FO 4490 (no suffix) at Medium charge and Standard MW. It lists FO 4490 SH and SHU at Medium charge and High MW, and FO 4490 SSH separately at High charge and Very High MW. Dropping the suffix collapses three different MW and charge positions into one misleading model string. A route chosen for root FO 4490 can fail an SSH duty.
How is the suffix confirmed?
The full bag label or the current TDS is used to confirm the suffix. Send us a photograph of the bag label or the document, and we can confirm which lane applies before the quotation is issued.
What are the three selection lanes?
Root duty (no suffix or suffix unclear): C8001 and C8015, matching Medium charge and Standard MW. SH and SHU: C8003 and C8035, matching Medium charge and High MW. SSH: C8005 with C8055 and C8006 as the bracket, matching the High charge and Very High MW position.
Can you provide documents with the quotation?
Applicable product documents can be reviewed for the grade quoted. A written trial protocol for the jar or CST test is provided with the quotation.
Which risks should the trial be designed to check?
Two. Dropping the SH, SHU or SSH suffix collapses three different historical MW and charge positions into one misleading model string. And a route chosen for root FO 4490 can fail an SSH duty through insufficient chain length or charge. The buyer bag label and same-sludge trial are the two tools that resolve both risks.
Is the SNF catalogue information current?
The powder catalogue is dated 2007. We cite it as a historical indicative source for MW and charge positions only. We do not claim it reflects current SNF product range, current specifications, or current availability. The ChinaPAM 26-grade master is the basis for the supply route we quote.
