Drewfloc 270 Equivalent — Anionic PAM Powder Grade Screening
ChinaPAM can accept a Drewfloc 270 enquiry and move to an anionic powder screening programme once the incumbent label, duty and operating conditions are locked. Send the exact label as printed — 270, not 290 or 302 — and the enquiry opens. ChinaPAM will quote the screening programme, discuss sample arrangements and request the intake conditions needed to rank candidate grades from measured results on your own material.

DREWFLOC is a trademark of its respective owner. ChinaPAM is an independent manufacturer and is not affiliated with, endorsed by, licensed by or a distributor for the brand owner. The grade name is used only to identify the product a buyer is comparing. The documents cited on this page are a third-party Solenis USA safety data sheet, a historical issuer product data sheet capture and a 2007 patent publication — none of them are ChinaPAM documents, and none of them establish anything about ChinaPAM. Our products are separately branded ChinaPAM grades and are not licensed copies.

Key Features
- Current granular identity taken from a single named safety data sheet version rather than inferred from a resale listing
- Drewfloc 270 kept strictly separate from 290 and 302 — the competitor grouping is not treated as proof of shared chemistry, and no sibling field is transferred in
- Charge and molecular-weight positions kept open because no accepted source publishes them — the trial on your material decides
- Published granular figures carried as safety-data values, not converted into a cross-vendor numeric match with any ChinaPAM code
- Anionic dry-polyacrylamide identity presented as historical issuer evidence, with a 2007 patent white-water table footnote as independent but bounded corroboration
- Preparation and shear conditions treated as a first-order trial variable, because the historical issuer sheet specifically warns that excessive mixing can break polymer bridges
- Three source-established facts and three evidence-based failure modes, each with a cheap verification step that catches it before bulk commitment
Applications
- Anionic powder selection for a confirmed Drewfloc 270 purchase requirement where the duty is a flocculating agent
- Bridging, settling, dewatering or clarification duties screened on the buyer's own material after intake, where the incumbent is the granular 270 grade
- White-water or process-water flocculation enquiries, screened on the actual feed — the 2007 patent white-water example is bounded evidence of identity, not an application recommendation
- Correcting an enquiry where 290 or 302 selection logic was applied to a 270 requirement without confirming the exact label

The supply answer first: an anionic powder screening programme, no grade pre-named
ChinaPAM accepts Drewfloc 270 alternative-supply enquiries and can quote an anionic powder selection programme once the incumbent label, the duty and the operating conditions are locked. That is the commercial answer.
No primary or backup grade is published in advance. The accepted sources establish that the incumbent is a granular anionic flocculating agent, but none of them publish a charge density or a molecular-weight tier — so there is no band to convert from. The programme starts with a controlled screen of the applicable ChinaPAM anionic powder range and ranks candidates only from measured results on your own material.
A quotation follows once the winning route is supported by a trial on the same material and by the applicable current ChinaPAM TDS, SDS and COA terms. Historical competitor values and approvals are not ChinaPAM specifications and are not compliance claims on our side. Price, stock and lead time belong to the quotation and are not stated from these documents.
Identity lock: 270 only — 290 and 302 stay outside this page
Send the label as printed: Drewfloc 270, plus the current incumbent TDS or safety data sheet if you hold one. The current record behind this page is a Solenis USA safety data sheet, version 2.1, covering Drewfloc 270 US polymer under material number 888138 — a USA material and version, in granular form.
Drewfloc 270, 290 and 302 often appear grouped together in competitor material. That grouping is a listing artefact, not evidence of shared chemistry or a shared supply route. Nothing published about 290 or 302 is carried onto this page, and nothing established here about 270 is generalised to the rest of the Drewfloc range. If your bags read 290 or 302, that is a different enquiry and needs its own evidence.
The historical anionic dry-polyacrylamide identity comes from an issuer product data sheet capture, and a 2007 patent table footnote corroborates anionic-polyacrylamide identity inside one bounded white-water example. Both are historical identity evidence. Neither is presented here as a current brand-owner specification, and neither tells you what the current formulation tolerance is.
Four facts the sources actually establish
Each fact below is tied to a specific document and locator, with the current and historical records kept apart.
| Fact | Source | What it does not establish |
|---|---|---|
| Drewfloc 270 US polymer, material 888138, is identified with its recommended use as a flocculating agent. | Solenis USA safety data sheet version 2.1, PDF page 1, identification and recommended use. | A recommended-use line is not a duty-specific performance statement for your process, and it establishes no charge or molecular-weight position. |
| The current sheet describes white to light-yellow granules with pH 7 at 10 g/L. | Solenis USA safety data sheet version 2.1, PDF page 4, physical properties. | Appearance and solution pH do not identify charge density, molecular weight or a comparable ChinaPAM grade. |
| The current sheet reports bulk density 650 kg/m³ and dynamic viscosity 200–300 mPa·s at 20 °C. | Solenis USA safety data sheet version 2.1, PDF page 5, physical properties. | These are safety-data values and the sheet does not expand the test preparation basis for the viscosity figure, so it cannot be read as a solution-viscosity specification or converted into a molecular-weight tier. |
| Historical issuer-document evidence identifies Drewfloc 270 as an anionic dry polyacrylamide, and a 2007 patent table footnote independently corroborates anionic-polyacrylamide identity in a bounded white-water example. | Historical issuer product data sheet capture; patent publication PDF page 14, Table 4 footnote (2007). | Historical identity evidence only, not a current specification. The white-water example is bounded to that patent's conditions and is not an application recommendation for your feed. |
Three failure modes and the check that catches each one
All three come out of the held evidence for this specific grade, not from general advice.
| Trigger | Consequence | Verification step |
|---|---|---|
| The 270 / 290 / 302 competitor grouping is treated as proof that all three share the same chemistry or the same supply route. The grouping is only a listing gap signal; the current safety data sheet and the historical issuer and patent evidence held here are specific to 270. | The quotation is built on the wrong product identity. | Require the full 270 label and the current incumbent TDS or safety data sheet. Do not transfer any field from a sibling number. |
| A single ChinaPAM anionic powder is named from ionic type alone. The current safety data sheet publishes neither charge nor molecular weight, and the historical capture does not justify a current cross-vendor band conversion. | Bridging, settling, dewatering or solution handling can miss the incumbent operating window. | Screen the applicable ChinaPAM anionic powder range on the same material and rank only from measured results. |
| Powder is under-wetted, or is exposed to excessive make-down or transfer shear. The historical issuer product data sheet capture specifically addresses wetting and mixing, and warns that excessive mixing can break polymer bridges. | Low apparent activity or damaged floc, which is then misread as a grade mismatch and sends the selection down the wrong path. | Record concentration, wetting, maturation, solution age, impeller and transfer conditions for every trial run. |
Route boundary: what the screen covers and what it will not assert
We reviewed our full anionic powder range against this enquiry before publishing the page, and the review ended without a nomination. That is the honest outcome when the incumbent's charge and molecular-weight positions are not published anywhere in the accepted records: every grade in the applicable range stays eligible until the buyer's own material ranks them.
What is known: the incumbent is a current granular flocculating agent, and the historical sources identify it as an anionic dry polyacrylamide. What is unknown: the current competitor charge and molecular weight, and any cross-vendor numeric match. What is therefore required: a screen on the same material. No ChinaPAM code is mapped numerically onto the incumbent anywhere on this page.
ChinaPAM does not manufacture the Drewfloc grade and makes no claim of identical formulation, drop-in substitution or guaranteed equivalent performance.
Intake, preparation, trial design and acceptance metrics
Useful intake, in order: quantity and destination; the full bag label and the current TDS or safety data sheet; the incumbent active dose stated as active polymer; the water, slurry or solids profile; pH; conductivity and hardness; equipment; throughput; and the clarity or solids targets the duty is judged by.
ChinaPAM powder preparation runs at a 1–3 g/L recommended window, 5 g/L maximum, and no longer than 60 minutes at working concentration. Preparation concentration is not process dosage. Powder make-down follows the applicable current ChinaPAM TDS for the grade being trialled. Historical competitor preparation numbers are context for reading the incumbent's behaviour — they are not ChinaPAM instructions and are not transferred into our make-down procedure.
Before dosing, control and record wetting, solution concentration, maturation, solution age and shear. This is not housekeeping: an under-wetted or over-sheared solution produces exactly the weak-floc symptom that gets blamed on grade selection, and the historical issuer sheet warns about the mixing side of it directly.
The trial runs the incumbent plus a bounded ChinaPAM anionic screen over a dose ladder on one representative feed, with mixing conditions held identical across all runs. The leading route is then repeated under adverse water or feed conditions — higher solids load, a seasonal feed change or off-spec pH — before anyone talks about a changeover.
Acceptance metrics are agreed before the first jar and compared on the same representative material: clarity or turbidity, settling or filtration rate, cake or underflow solids, active dose, throughput, floc shear tolerance and solution operability.
Go/no-go: advance when the exact identity is locked and one tested ChinaPAM route meets the pre-agreed process and operability targets. If charge or molecular-weight uncertainty is still unresolved after the screen, the next step is to request the incumbent TDS or keep the enquiry open for further screening — not to name a grade and hope. Current price, stock status, lead time, applicable TDS and sample arrangements are confirmed in the quotation. Batch-specific COA terms are confirmed with the shipment.
Brand Equivalents & Replacements
ChinaPAM accepts a confirmed Drewfloc 270 enquiry and screens its applicable anionic powder range against it. No single grade is named before the duty and operating conditions are reviewed, because the accepted sources publish no charge or molecular-weight band to aim at. Label confirmation and feed intake come first, then a quotation, and sample arrangements are discussed from there. Nothing on this page is a tested replacement or an equivalent-performance statement: only a controlled trial on your own material can show whether a screened route holds up on your duty.

Frequently Asked Questions — Drewfloc 270 Equivalent — Anionic PAM Powder Grade Screening
Can ChinaPAM supply for a Drewfloc 270 requirement?
Yes — ChinaPAM accepts Drewfloc 270 alternative-supply enquiries and quotes an anionic powder selection programme once the label, duty and operating conditions are locked. Send the exact label as printed, or a bag photo, with the quantity and destination, and the enquiry opens. ChinaPAM will discuss sample arrangements and the trial plan from there. No drop-in or identical-formula claim is made.
Why is no specific ChinaPAM grade named for Drewfloc 270?
Because none of the accepted sources publish a charge density or a molecular-weight tier for the incumbent. The current Solenis USA safety data sheet version 2.1 gives appearance, pH, bulk density and dynamic viscosity, and the historical records give anionic dry-polyacrylamide identity — none of that is a band to aim at. Naming one grade from ionic type alone would be a guess. The applicable anionic powder range is screened on your own material and ranked from measured results.
My supplier lists Drewfloc 270, 290 and 302 together. Can I use information about 290 or 302 here?
No. That grouping is a listing artefact and is not evidence of shared chemistry or a shared route. The current safety data sheet and the historical issuer and patent evidence behind this page are specific to 270. Transferring a sibling's published fields onto a 270 enquiry is how a quotation ends up built on the wrong product identity. If your bags read 290 or 302, send that label and it is treated as a separate enquiry.
The safety data sheet gives a dynamic viscosity of 200–300 mPa·s. Can I match a ChinaPAM grade to that number?
Not directly. That is a safety-data value and the sheet does not expand the test preparation basis behind it, so there is no stated concentration or method to reproduce. A viscosity figure without its preparation basis cannot be converted into a molecular-weight tier or lined up against a ChinaPAM figure measured on a different basis. It is useful as a sanity check on form, not as a selection criterion.
A 2007 patent uses Drewfloc 270 in a white-water example. Does that mean it suits my application?
No. The patent table footnote is cited because it independently corroborates anionic-polyacrylamide identity, and that is all it is used for here. The white-water example is bounded to the conditions that patent describes. It is not an application recommendation, and the result is not transferred to your feed, your equipment or your targets.
My first trial gave weak floc. Does that mean the grade is wrong?
Check the make-down before you change chemistry. The historical issuer product data sheet capture addresses wetting and mixing directly and warns that excessive mixing can break polymer bridges, so an under-wetted solution or too much transfer shear produces low apparent activity that looks exactly like a grade mismatch. Record concentration, wetting, maturation, solution age, impeller and transfer conditions for each run, confirm those are sound, and only then move the charge or molecular-weight bracket.
What is confirmed in the quotation, and what is not stated here?
Current price, stock status, lead time, applicable TDS and sample arrangements are confirmed in the quotation. Batch-specific COA terms are confirmed with the shipment.
