Field note Textile Mills · CPAM Supplier in Pakistan

AAS dispatched a three-cationicity sample kit (25 / 40 / 55 mol%, 1 kg each) to a Faisalabad dye-house in March 2026; jar-test selected 40 mol% at 11M Da; first commercial order landed at 1.2 MT/quarter on contract.

Programme spec

Dosing programme outline

Programme outline below is the AAS default for textile mills applications. Final dose is set against the customer's source-water analysis, equipment metallurgy, and operating cycles. Every drum ships with a Certificate of Analysis; SDS is shipped pre-shipment for HSE-document review.

Molecular weight: 8–14 × 10⁶ Da (jar-test selected)
Cationic degree: 10–80% (specify on order)
Solid content: ≥ 90% white granular powder
Typical sludge-dewater dose: 1–10 kg per dry-tonne sludge
Typical wastewater dose: 0.2–5 ppm on liquor
Make-down concentration: 0.1–0.3% w/v dissolved stock
MOQ: 25 kg bags; full pallet 600 kg; 1 MT bulk
Lead time: Ex-Karachi stock; 4–6 wks factory-direct on bulk replenishment

Why this matters in textile mills

Why a textile-mill CPAM call is a per-machine call, not a per-mill one

Two dye-houses in the same Faisalabad cluster can buy the same CPAM and get different sludge-dewatering results. The reason is wet-end charge state: reactive-dye load on cotton sits at a different zeta potential than disperse-dye effluent on polyester, and the cationicity of the CPAM has to match that charge. A 20 mol% cationic CPAM at 12 million MW handles primary-clarifier flocculation on hydrolysed-reactive liquor; a 55 mol% cationic at 10 million MW handles belt-press dewatering on the sludge from that same plant. AAS imports the full grade range and runs a jar test on the customer's actual liquor before committing the order — that jar-test step is what separates a programme that lands cake at 24% dry solids from one that lands at 16%.

What a CPAM supplier in Pakistan actually has to deliver

Buying CPAM in Pakistan from a local distributor usually means buying a single grade — a fixed cationicity, a fixed molecular weight, often relabeled from a Chinese manufacturer with a 30–40% markup. The cost shows up at the belt press: under-cationic CPAM passes through the cake into the filtrate, over-cationic CPAM over-charges the floc and leaves the cake greasy. A textile-mill effluent buyer needs three things from a supplier — access to the full cationicity ladder (10 / 25 / 40 / 55 / 70 mol%), at least three molecular-weight bands (8M / 10M / 12M Da), and a jar-test sample loop before the first commercial drum lands. Austin Anderson Solutions imports CPAM from Shaanxi Ande Technology Industry on a sole-Pakistan-agent agreement and holds 25 kg bags ex-Karachi across the cationicity range. Sample dispatch to a Lahore or Faisalabad dye-house takes 24–48 hours; jar-test results back to the chemistry engineer within a week.

Dosing windows and where CPAM sits next to PAC

CPAM is rarely the only chemistry on a textile-effluent train. The standard sequence is PAC into the rapid-mix tank for charge neutralisation and primary coagulation, pH trim to 6.5–7.5, then CPAM into the slow-mix flocculation tank for floc-bridging and settling-rate gain. PAC dose lands at 60–250 ppm depending on dye load; CPAM dose at 0.5–4 ppm on the liquor at the slow-mix stage, and 1–10 kg per dry-tonne at the belt press or centrifuge for sludge dewatering. The dosing logic is in the product spec, but the dose number that fires in the plant is set by the jar test — not by a generic recipe.

Supply discipline: COA per batch, MSDS pre-shipment

A Pakistani textile mill cannot afford a stock-out on the flocculant line. Production loss on a stopped clarifier is measured in lakhs per shift, plus a regulatory exposure on COD and colour at the discharge monitoring point. AAS holds buffer stock in Karachi across the contracted CPAM grade range; the supply charter includes 99% availability, monthly bulk replenishment on contracted volume, and a COA per batch with the active-monomer residual disclosed. The MSDS ships ahead of the consignment for HSE-document review.

Procurement FAQ

Questions procurement teams ask first.

What cationic degree of CPAM do I need for textile-mill sludge dewatering?

Most reactive-dye sludges land at 40–55 mol% cationic. Disperse-dye and PET-finishing sludges land at 25–40 mol%. The cationicity has to be set against the substrate-charge titration on the actual sludge, not on the parent dye class. AAS dispatches a sample kit of three cationicities before the first commercial order to confirm.

What is the MOQ for CPAM supply in Pakistan?

Ex-Karachi stock: 25 kg bags single-bag minimum, full pallet 600 kg. Factory-direct from Shaanxi Ande: 1 MT bulk minimum on contracted grades. Quarterly contracts at ≥ 5 MT/year unlock per-kg pricing improvement and dedicated stock allocation.

How fast can a sample reach a Faisalabad or Lahore dye-house?

Standard sample kit (three cationicities, 1 kg each) ships from Karachi same business day. Lahore / Faisalabad delivery 24–48 hours via PAFEX or M&P. Jar-test methodology supplied with the kit.

Does CPAM degrade in storage?

Solid-form CPAM stored sealed at < 35°C is stable 24 months. Once dissolved to 0.1–0.3% w/v stock, useful life is 24–48 hours; viscosity drops measurably after that. Make-down skids should be sized for daily dissolved-stock turnover, not weekly.

How does CPAM cost-in-use compare with imported Kemira / BASF / Solenis equivalents?

On equivalent active-monomer basis and cationicity-matched grade, Shaanxi Ande CPAM lands at roughly 30–45% below Kemira / BASF list price CIF Karachi, with the same chemistry function. The Cost-in-Use calculator at /calculators/cost-in-use/ normalises against active concentration so the comparison stays honest.
