Wholesale Cationic Polyacrylamide (CPAM) Suppliers from China - Effective Water Treatment Solution from Trusted Factory Manufacturer, Manufacturers

Cationic Polyacrylamide, commonly referred to as CPAM, is a highly effective water-soluble polymer characterized by its positively charged molecular chain (-NH₃⁺). This unique property enables CPAM to engage in charge adsorption + net capture interactions with negatively charged suspended solids, such as clay, colloids, dissolved organic matter like humic acid, and harmful pollutants including dye anions in water. As a result, it swiftly aggregates and eliminates fine particles, positioning itself as a powerful tool for decolorization and impurity removal. Ideal for applications in low turbidity and high pollution environments, CPAM is extensively used in industries such as printing and dyeing, electroplating, and chemical engineering. As a leading China supplier and factory of Cationic Polyacrylamide, we provide top-quality products designed to meet the diverse needs of our clients across various sectors.

Product Description

Core Features
Feature 01

Adjustable Ionicity • Precise Adaptation: Ionicity (cationic charge density) ranges from 10% to 80% (adjustable), customizable according to the negative charge intensity of wastewater:

Low ionicity (10%–30%): Suitable for low turbidity, weakly negatively charged wastewater (such as surface water pretreatment).

High ionic degree (50%–80%): Suitable for wastewater with high negative charge and fine suspended solids (such as printing and dyeing wastewater, electroplating wastewater).

Cationic PAM Powder Adjustable Ionicity
Feature 02

Fast dissolution, low residue: The dissolution time of powder PAM ≤ 60 minutes (at room temperature). After dissolution, the flocs are large and settle quickly (settling speed is 25%–40% faster than conventional products), and it works better when used in combination with PAC. Water insoluble matter ≤ 0.5%.

Feature 03

Strong Tolerance: Resistant to acid and alkali (pH 3–12), temperature-resistant (−5°C to 90°C), suitable for multiple scenarios such as mine wastewater, papermaking black liquor, printing and dyeing wastewater, and oilfield reinjection water.

Fast dissolving PAM flocculant settling test
Application Area
  • Municipal sewage treatment: Accelerate sludge dewatering and improve purification efficiency.

Frequently Asked Questions
What is the ionicity range of this cationic PAM, and how do I choose the right grade?
The ionicity (cationic charge density) of this PAM ranges from 10% to 80% and is fully adjustable. For low-turbidity or weakly negatively charged wastewater such as surface water pretreatment, a low ionicity grade (10%–30%) is recommended. For wastewater with high negative charge and fine suspended solids — such as printing and dyeing or electroplating wastewater — a high ionic degree (50%–80%) is more suitable.
How long does the powder PAM take to dissolve, and can it be used with PAC?
The dissolution time of powder PAM is ≤ 60 minutes at room temperature. After dissolution, flocs are large and settle quickly — 25%–40% faster than conventional products. It performs even better when used in combination with PAC (polyaluminum chloride), making it ideal for enhanced coagulation processes.
What pH and temperature conditions can this PAM withstand?
This cationic PAM is highly tolerant to both acidic and alkaline environments, functioning effectively across a pH range of 3–12. It is also temperature-resistant, performing reliably from −5°C to 90°C, making it suitable for a wide range of industrial and environmental applications.
What industries and applications is this cationic PAM suitable for?
This product is widely used across multiple sectors, including municipal sewage treatment (sludge dewatering), industrial wastewater treatment (steel mills, electroplating plants, paper mills), oilfield exploitation (improving oil recovery and adjusting water injection viscosity), paper and textile manufacturing (enhancing paper strength and reducing fiber loss), and agricultural soil improvement (preventing erosion and enhancing water retention).
What packaging options are available, and can custom branding be arranged?
The product is available in 25kg woven bags lined with plastic bags, as well as 1-ton jumbo bags for bulk orders. Custom packaging with English labeling or customer logo printing is available upon request, making it convenient for international distribution and brand requirements.
What are the storage requirements and shelf life for this product?
The solid powder PAM should be stored in a cool, dry place at temperatures ≤ 35°C, away from direct sunlight and moisture. When kept in its original, unopened packaging under these conditions, the shelf life is 2 years.
