FLOPAM FO 4240 Equivalent — Bare-Grade Cationic PAM Selection
ChinaPAM supplies cationic PAM for the named FLOPAM FO 4240 replacement-screening project and can quote a documented candidate route, provide applicable documents, and arrange a sample or same-feed trial plan now. Before anything else: this page is the bare FO 4240 grade string only. FO 4240 SH and FO 4240 SSH are separate catalogue positions with different charge and molecular-weight placements, so send the full grade string as printed on the bag label and we will confirm which lane applies.

Applications
- Buyer context: replacement screening for the named grade

What the SNF 2007 Catalogue Publishes for FO 4240
Page 11 of the SNF FLOPAM powder catalogue dated 2007 lists FO 4240 as a cationic powder at Low charge and Standard MW. The same entry carries an approximate bulk density of 0.85, a recommended make-up concentration of 5 g/L with a maximum of 10 g/L, a dissolution time of 60 minutes at 5 g/L in deionised water at 25 °C, a catalogue shelf life of 24 months, and packaging in 25 kg bags and 750 kg big bags.
These are historical catalogue facts. We cite them to establish the screening direction and the make-down basis a comparison has to be run on. We do not present them as current SNF specifications, current availability, or contractual values.
| Property | Catalogue value (historical) |
|---|---|
| Ionic type and form | Cationic powder |
| Charge position | Low charge |
| Molecular-weight position | Standard MW |
| Bulk density | Approximately 0.85 |
| Make-up concentration | Recommended 5 g/L, maximum 10 g/L |
| Dissolution time | 60 minutes at 5 g/L, 25 °C, deionised water |
| Shelf life | 24 months |
| Packaging | 25 kg bags, 750 kg big bags |
The Suffix Question Comes First
FO 4240, FO 4240 SH and FO 4240 SSH are listed as separate entries in the catalogue, at different charge and molecular-weight placements. This page addresses the bare grade string only. A route built for the bare grade points at the wrong placement if the bag in your store actually carries SH or SSH.
So the first thing we ask for is the grade string as printed on the bag label, with a photograph if one is available. Until the suffix is confirmed we treat the enquiry as the bare grade and say so in the quotation, rather than assuming a lane.
Ten Procurement Decision Checks Before You Order
These are the checks we work through with a buyer on this position. Each one either confirms the route or changes it, and each is answered before a quotation is treated as firm.
| Check | Why it decides the order | What we need |
|---|---|---|
| 1. Grade string and suffix | SH and SSH are separate catalogue positions with different placements | Full string as printed on the bag label, photograph if available |
| 2. Physical form | A powder route and a liquid route are handled differently on site | Confirmation the incumbent is the powder product |
| 3. Charge position basis | Catalogue Low charge and our qualitative Low band are different scales | Acceptance that the position sets direction, not equivalence |
| 4. Molecular-weight direction | C8008 sits at Medium MW on our band against a Standard MW catalogue entry | Agreement to hold C8001 / C8015 as the longer-chain option |
| 5. Active content and dose basis | A dose figure without an active basis cannot be compared | Your current dose and the basis it is expressed on |
| 6. Make-up concentration | Catalogue reference is 5 g/L with a 10 g/L maximum | Your site solution strength |
| 7. Make-down water and temperature | Catalogue dissolution reference is deionised water at 25 °C for 60 minutes | Your water source, hardness if known, and temperature |
| 8. Downstream equipment | Shear and residence time change which chain length works | The machine and dosing arrangement the polymer feeds |
| 9. Documents required | Document requirements differ by destination and by buyer | The document list your procurement process needs |
| 10. Packaging and shelf life planning | Catalogue reference is 25 kg bags and 750 kg big bags at 24 months | Your packaging preference and storage conditions |
What We Will and Will Not Claim
ChinaPAM supplies cationic PAM. 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 screen an alternative against.
We do not claim our grades reproduce the FLOPAM specification, and we do not claim our qualitative charge and molecular-weight descriptors convert to the SNF scale. The catalogue figures quoted here are historical catalogue facts from a 2007 document. What settles the screening is a same-feed trial on your own material at a matched active dose and a stated make-down basis.
Dosage Guide
Use your current FO 4240 rate as the starting reference, then confirm it with a same-feed trial on your own material. State the solution strength your rate was measured at, because the catalogue reference for the FLOPAM grade is 5 g/L with a 10 g/L maximum and a different strength changes the comparison. Prepare and make up the quoted grade according to the applicable product documents for the ChinaPAM grade quoted.
Frequently Asked Questions — FLOPAM FO 4240 Equivalent — Bare-Grade Cationic PAM Selection
Does this page cover FO 4240 SH and FO 4240 SSH?
No. The SNF 2007 catalogue lists those as separate positions with different charge and molecular-weight placements, so they are different screening lanes. This page is the bare FO 4240 grade string only. Send the full string as printed on the bag label and we will confirm which lane your plant actually needs before any quotation goes out.
What does the SNF 2007 catalogue publish for FO 4240?
Page 11 lists it as a cationic powder at Low charge and Standard MW, with an approximate bulk density of 0.85, a recommended make-up concentration of 5 g/L and a maximum of 10 g/L, a dissolution time of 60 minutes at 5 g/L in deionised water at 25 °C, a catalogue shelf life of 24 months, and packaging in 25 kg bags and 750 kg big bags. These are historical catalogue facts from a 2007 document, not current SNF specification or availability.
Which ChinaPAM grade do you screen first?
C8008, a Low charge and Medium MW cationic powder. It is the closest documented starting point to the catalogue Low charge position. C8001 and C8015 are held as the longer-chain option if the same-feed trial shows the floc needs more chain length. We do not describe any of these as a match to the FLOPAM grade; the trial decides.
Why does the make-up concentration matter for a comparison?
Because a dose figure only means something alongside the solution strength it was measured at. The catalogue recommends 5 g/L for the FLOPAM grade with 10 g/L as the maximum. If your site runs a different strength, or if your make-down water and temperature differ from the catalogue reference of deionised water at 25 °C, the comparative dose will read wrong before the polymer has had a chance to perform. We confirm the basis in writing with the quotation.
Which two unconfirmed items would most likely cause a selection error here?
First, an unconfirmed suffix. If the bag is actually FO 4240 SH or SSH, the catalogue position is different and this bare lane points at the wrong charge and molecular-weight placement. Second, an unconfirmed active content and make-down basis. Our qualitative band descriptors are not the same scale as the catalogue descriptors, so without a matched active dose, matched solution strength and your own water and temperature, the trial can read as a polymer failure when it is a make-down mismatch.
What do you need from us to open the quotation?
The full grade string as printed on the bag label including any suffix, a bag-label photograph if you have one, your purchasing quantity, the make-down water and temperature you use, your current solution strength and dose basis, and the equipment the polymer feeds. That is enough to issue a documented candidate route, the applicable documents, and a written same-feed trial protocol.
