FLOPAM FO 4350 SH Equivalent — Medium-Charge High-MW Cationic PAM Grade-Selection Screening
ChinaPAM accepts a FLOPAM FO 4350 SH enquiry and screens two deliberate routes: C8001 to preserve the medium-charge position and C8003 to preserve the high-MW position. The SH suffix in the grade string is mandatory — it identifies a different product family from bare FO 4350 and from the SHU series. Send the full label with the SH suffix and ChinaPAM will open the enquiry, quote the bracket and discuss sample arrangements.

Key Features
- Medium-charge / high-MW cationic powder identity documented in an exact FO 4350 SH column of the 2007 SNF catalogue
- SH suffix locked separately from bare FO 4350 (a different root grade entry in the SNF catalogue) and FO 4000 SHU series (a separate series with a different suffix)
- 625/340/140 cps viscosity ladder preserves the specific High-MW column for make-down baseline reference
- C8001 primary preserves the medium-charge direction; C8003 backup checks the high-MW direction on the same feed
- Make-down conditions drawn directly from the historical catalogue: 4 g/L recommended, 10 g/L max, 60 min dissolution
- SH versus SHU distinction noted for feeder and hydration equipment decisions before trial
- Historical 2007 source identity; current TDS or COA requested from the buyer to confirm current specification
Applications
- Buyer-confirmed cationic powder dosing duty where medium charge and high MW have been established as the incumbent position — actual application type confirmed with buyer
- Same-feed screening between C8001 (charge-aligned primary) and C8003 (MW-aligned backup) where the SH suffix is confirmed on the label
- Procurement matching a confirmed FLOPAM FO 4350 SH purchase requirement with SH suffix on the bag

Supply answer: C8001 on charge, C8003 on MW, route settled on same feed
ChinaPAM accepts a FLOPAM FO 4350 SH enquiry and screens two deliberate routes. C8001 starts as the charge-aligned primary: its medium-charge position on the ChinaPAM cationic scale matches the medium-charge catalogue entry. C8003 is the MW-aligned backup: its high-MW position anchors the other axis and checks whether stepping up in MW and charge improves the feed response.
Neither is a drop-in or a performance-guaranteed replacement. The buyer's job is to choose between preserving the medium-charge position (C8001 direction) and preserving the high-MW position (C8003 direction), then close the route from floc strength, drainage, filtrate and cake results on the same feed.
Price, stock and lead time belong to the quotation and are not stated from the historical catalogue.
SH suffix: why it is mandatory and how it differs from bare FO 4350 and SHU
The SNF 2007 catalogue places FO 4350 SH in the FO 4000 SH & SHU table as its own High-MW column with a specific 625/340/140 cps viscosity ladder. Bare FO 4350, FO 4350 SH and the FO 4350 SHU variant are separate historical catalogue entries — they share the number but have distinct bulk-density and viscosity profiles. Bare FO 4350 is a separate root grade entry with a different description; FO 4350 SHU is part of a separate series. Neither should be merged into the FO 4350 SH enquiry.
SH and SHU are not interchangeable suffixes. They differ in bulk density and viscosity profile relevant to feeder and hydration equipment decisions. Dropping the SH and substituting SHU because both share the number would introduce a different viscosity and density profile before the trial starts.
Send the full FO 4350 SH label including the SH suffix. ChinaPAM will carry the exact suffix through the enquiry unchanged.
Three facts the sources actually establish
All three facts come from a single SNF source: the historical 2007 FLOPAM powder catalogue, page 7.
| Fact | Source and locator | What it does not establish |
|---|---|---|
| FO 4350 SH is a distinct entry in the FO 4000 SH & SHU table, listed as Medium charge / High molecular weight cationic powder. | SNF FLOPAM historical powder catalogue 2007; PDF page 7; text lines 448–513. | Does not establish current SNF specification, current availability or cross-vendor numeric equivalence. |
| The table lists approximate bulk density 0.85 and Brookfield viscosities 625 / 340 / 140 cps at 5.0 / 2.5 / 1.0 g/L. | SNF FLOPAM catalogue 2007; PDF page 7; text lines 536–570. | Historical catalogue average indicative values only; not verified as current brand-owner specification. |
| The table lists 4 g/L recommended, 10 g/L maximum and 60 minutes dissolution in deionised water at 5 g/L and 25 °C; one-day solution stability; 0–35 °C storage; conditional 24-month shelf life (stable indoor 5–30 °C); 25 kg bags and 750 kg big bags. | SNF FLOPAM catalogue 2007; PDF page 7; text lines 571–595. | Historical indicative values. Shelf-life footnote requires stable indoor 5–30 °C. Not ChinaPAM specifications. |
Two failure modes and the check that catches each one
Both arise from suffix conflation or single-axis selection without a trial.
| Trigger | Consequence | Verification step |
|---|---|---|
| The SH suffix is dropped or SHU is substituted because both share the number. | The different bulk-density and viscosity profile used by feeder and hydration decisions is lost; the wrong equipment baseline is used for the trial. Bare FO 4350 is a separate root grade entry and FO 4000 SHU is a separate series — each has its own catalogue identity. | Lock SH on the label and in every route document. Bare FO 4350 and FO 4000 SHU are separate catalogue entries with different profiles — treat them as distinct grades, not as interchangeable with the SH enquiry. |
| A medium-charge-only choice preserves charge but may understate the High-MW direction; a High-MW-only choice raises charge and may over-neutralise the suspension. | Performance diverges on floc strength, drainage or cake compared with the incumbent, and the root cause is not identified. | Screen C8001 on the charge axis and C8003 on the MW axis on the same feed. Fix the route from measured floc strength, drainage, filtrate clarity and cake response. |
Intake, trial design and acceptance metrics
Useful intake: full FO 4350 SH label with SH suffix; current TDS or COA if the buyer holds one; sludge type and source; solids percentage; pH; incumbent active dose; dewatering equipment; make-down water quality (hardness, conductivity, temperature); trial quantity and destination.
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.
The historical catalogue specifies 4 g/L recommended, 10 g/L maximum and 60 minutes in deionised water at 25 °C for the incumbent. Carry those values as historical context only — apply ChinaPAM TDS make-down instructions for the quoted grade, not the catalogue values.
Trial design: run the incumbent, C8001 and C8003 on the same fresh feed. Establish the incumbent active-polymer basis from a current applicable issuer document, TDS, COA or batch record before comparing; a matched active-polymer dose is used only once that basis is established — if documentation is unavailable, compare across a documented dose-response ladder without asserting active-mass equivalence. Document make-down water quality, temperature, concentration, maturation time, solution age at application and mixing conditions for each run.
Measure and compare floc strength, drainage rate, filtrate clarity and cake response. Agree acceptance metrics before the first run. 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.

Frequently Asked Questions — FLOPAM FO 4350 SH Equivalent — Medium-Charge High-MW Cationic PAM Grade-Selection Screening
Can ChinaPAM supply for a FLOPAM FO 4350 SH requirement?
Yes — C8001 as the medium-charge primary and C8003 as the high-MW backup. Send the full label with SH suffix and the enquiry opens. Neither grade is a drop-in; the route is confirmed by a same-feed trial.
Why is the SH suffix mandatory?
Because FO 4350 SH has its own High-MW column and 625/340/140 cps viscosity ladder in the 2007 SNF catalogue, as a distinct entry from bare FO 4350 (a different root grade entry with a different catalogue description). The SH versus SHU distinction also affects feeder and hydration equipment choices.
Is FO 4350 SH the same as FO 4000 SHU or bare FO 4350?
No. Bare FO 4350 is a separate root-grade entry in the SNF catalogue. FO 4000 SHU is a separate series. FO 4350 SH is a distinct column in the FO 4000 SH & SHU table with its own bulk density and viscosity values. These are three separate products.
Why start with C8001 rather than a higher-MW grade?
Because the catalogue lists FO 4350 SH at Medium charge first. Preserving the charge position is the primary screening direction; C8001 does that on the ChinaPAM scale. C8003 then checks whether stepping up in MW (at higher charge) improves the result.
The catalogue value is 4 g/L recommended make-down. Should I use that for ChinaPAM grades?
No. The 4 g/L and 60-minute values are historical catalogue guidance for the SNF incumbent. Use the ChinaPAM TDS make-down instructions for the quoted grade. ChinaPAM general guidance runs at 1–3 g/L recommended, 5 g/L maximum, ≤60 minutes at working concentration.
What is confirmed in the quotation, and what is not stated here?
The quotation confirms the selected ChinaPAM grade, applicable TDS/SDS, ChinaPAM packaging options, current MOQ, quantity and destination, current price and lead time, and sample or trial arrangements. Batch-specific COA terms are confirmed with the shipment. The 2007 SNF historical catalogue packaging values (25 kg bags, 750 kg big bags) are historical incumbent data only — ChinaPAM packaging is confirmed in the quotation.
