FLOPAM FO 4990 SH Equivalent: Two-Lane Cationic PAM Screening
ChinaPAM supplies cationic PAM powder and can quote against a FLOPAM FO 4990 SH enquiry. The held SNF 2007 catalogue publishes FO 4990 SH at Very High charge and High MW; no grade in our current public master carries that band pair, so we screen two candidate lanes instead of naming one. Contact us to discuss pricing, sample arrangements and applicable product documents.

Key Features
- Cationic PAM powder supply route quoted against a confirmed FO 4990 SH label
- SNF publishes FO 4990 SH on page 9 at Very High charge and High MW on its own scale
- Published Brookfield row 560/310/130 cps at 5/2.5/1 g/L with a 4 g/L / 10 g/L / 60-minute make-up line
- No grade in our current public master carries that band pair — the gap is stated, and two candidate lanes are screened
- Covers the SH suffix only; bare FO 4990 is handled on its own page
- Contact us to discuss pricing, sample arrangements and applicable product documents.
Applications
- Confirming that your label reads FO 4990 SH rather than the bare grade before a route is quoted
- Checking whether your make-up and dosing system suits our 1–3 g/L preparation window
- Comparing the two candidate lanes on your own material at your working concentration
- Assembling the information needed for a quotation and for review of applicable product documents

What the Held Catalogue Prints for FO 4990 SH
The source for this page is SNF SAS Catalogue 2007 Poudres. Page 9 prints FLOPAM FO 4990 SH, described on SNF’s own scale as Very High charge and High molecular weight, with Brookfield readings of 560 cps at 5 g/L, 310 cps at 2.5 g/L and 130 cps at 1 g/L, and a make-up line of 4 g/L recommended, 10 g/L maximum, 60 minutes. Those are 2007 figures given for information only, not a current specification, and we make no claim about what SNF supplies today.
The suffix matters here as a matter of identification. This page is about FO 4990 SH specifically. The held catalogue documents the SH grade separately from the bare FO 4990 designation, so we do not read the SH row onto an unsuffixed label. Keeping them apart is how we avoid quoting one row under the other’s name.
Why We Put Two Lanes Forward Instead of One Grade
Our current public grade master describes cationic powders by qualitative charge and molecular-weight bands. The grades we publish at Very High charge are published at Very High molecular weight; the grades we publish at High molecular weight are published at High charge. Nothing in that master pairs Very High charge with High molecular weight the way the catalogue row for FO 4990 SH does. That is a real gap and we would rather name it here than let a buyer discover it later.
So the offer is two candidate lanes: a charge-priority lane taken from our Very High charge grades, and a chain-band-priority lane taken from our High molecular weight grades. We are not claiming either lane brackets, straddles or numerically approximates the SNF row — the band descriptors on each side are set by each manufacturer independently, and we do not convert between the two scales. What we are saying is that both are credible starting candidates for a comparison, and that the comparison, run on your material, is what picks one.
This does not hold up a quotation. Send the label, quantity and destination and we can price the enquiry, discuss sample options for both lanes and tell you which product documents apply to whichever grade is quoted.
Running the Comparison So the Result Means Something
Prepare both of our candidates at 1–3 g/L, maximum 5 g/L, with dissolution within 60 minutes at working concentration. Do not make them up at the 4 g/L or 10 g/L figures printed on this page: those belong to the FLOPAM grade, and using them changes the dissolved polymer mass per litre of solution so that a dose equal by volume is not equal by active polymer.
Run both lanes against your incumbent on the same material, on the same day, at several dose rates, dosing on the basis of active polymer. Record what you measure rather than reasoning from the band labels — the labels are what created the ambiguity in the first place. Send the results to us and we will go through them with you and quote the lane that earned it.
Dosage Guide
Establish the working dose on your own material rather than transferring it from a table. Your current FO 4990 SH active dose rate is the useful starting reference. Prepare our powder at 1–3 g/L, maximum 5 g/L, with dissolution within 60 minutes at working concentration. The SNF make-up figures quoted on this page (4 g/L recommended, 10 g/L maximum) are historical indicative values published for FO 4990 SH and are not our preparation parameters.
Frequently Asked Questions — FLOPAM FO 4990 SH Equivalent: Two-Lane Cationic PAM Screening
Can you quote a cationic PAM powder for a FLOPAM FO 4990 SH enquiry?
Yes. ChinaPAM supplies cationic PAM powder and can quote against FO 4990 SH duty. Because no grade in our current public master carries the same band pair the catalogue prints for FO 4990 SH, we put two candidate lanes forward rather than naming one, and we compare them on your own material before a changeover.
What do you need from me to prepare a quotation?
The complete grade string with the SH suffix, the quantity and destination, and your current make-up concentration if you have it. That is enough to price the enquiry and discuss sample options for both candidate lanes.
Why two lanes instead of one named grade?
The catalogue prints FO 4990 SH at Very High charge and High molecular weight. Our current public master publishes Very High charge grades at Very High molecular weight, and High molecular weight grades at High charge — no grade of ours pairs the two the way that row does. Rather than pick one and imply it matches, we put both forward: a charge-priority lane and a chain-band-priority lane. Which one suits your material is a question for the comparison, not for this page.
Do you claim either lane is the same product as FO 4990 SH?
No. Neither lane is offered as exact, identical or a drop-in for FO 4990 SH, and FLOPAM is SNF’s trademark. The band descriptors on each side are set by each manufacturer independently, so we do not convert one scale into the other or present a lane as a numerical match.
What does the sample plan verify?
It settles which lane suits your material, which is the open question this page cannot answer from published bands alone. Prepare both candidates at 1–3 g/L — not at the 4 g/L SNF figure on this page, which belongs to a different product — dose on the basis of active polymer rather than product weight, run both on the same material on the same day at several dose rates, and record the results. Send them to us and we will review them with you before quoting a route for volume supply.
Does this page cover bare FO 4990 as well?
No. This page covers the SH suffix only. The held catalogue documents FO 4990 SH separately from the bare designation, and we do not carry the SH row across to an unsuffixed label. If your label reads FO 4990 without a suffix, send it to us through the enquiry row on the brand equivalents hub and we will work from what the label says.
