Wholesale Cationic Polyacrylamide (CPAM) from China - Leading Suppliers and Factory for Water Treatment Solutions Manufacturers, Factories

Cationic Polyacrylamide (CPAM) is a highly effective, water-soluble polymer characterized by its positively charged molecular chain (-NHâ‚ƒâº). As a leading product among suppliers in China, CPAM excels in its ability to engage in charge adsorption + net capture interactions with negatively charged suspended solids, such as clay and colloids, as well as dissolved organic matter like humic acid and various pollutants, including dye anions. This unique property allows CPAM to swiftly aggregate and eliminate fine particles, positioning it as an indispensable tool for decolorization and impurity removal. It is particularly valuable in applications with low turbidity and high contamination, including industries such as printing and dyeing, electroplating, and chemical engineering. As a trusted factory for Cationic Polyacrylamide, we prioritize quality and effectiveness, making CPAM the ideal choice for effective water treatment solutions

Product Description

Core Features

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).

Adjustable Ionicity and Precise Adaptation

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%.

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.

Application Area

✓ Municipal sewage treatment: Accelerate sludge dewatering and improve purification efficiency.
✓ Industrial wastewater treatment: Treatment of high-concentration wastewater from steel mills, electroplating plants, paper mills, etc.
✓ Oilfield exploitation: Improve oil recovery and adjust water injection viscosity.
✓ Paper and Textile: Enhance paper strength and reduce fiber loss.
✓ Soil improvement: Prevent soil erosion and enhance soil water retention.

Packaging and Storage

Solid powder: 25kg woven bag lined with plastic bag / 1 ton jumbo bag (customizable English / customer logo packaging available);

Storage Conditions: Store in a cool, dry place (temperature ≤ 35°C), avoid direct sunlight; the shelf life of the solid is 2 years (unopened).

Frequently Asked Questions

Q What is the difference between low ionicity and high ionicity cationic PAM?

Low ionicity (10%–30%) cationic PAM is best suited for low turbidity, weakly negatively charged wastewater such as surface water pretreatment. High ionicity (50%–80%) is designed for wastewater with high negative charge and fine suspended solids, such as printing and dyeing wastewater or electroplating wastewater. Selecting the correct ionicity ensures optimal flocculation performance.

Q How long does it take for powder PAM to fully dissolve?

The dissolution time of powder PAM is ≤ 60 minutes at room temperature. After dissolution, the resulting flocs are large and settle quickly — 25%–40% faster than conventional products. Performance is further enhanced when used in combination with PAC (Polyaluminum Chloride).

Q What pH and temperature range is cationic PAM suitable for?

Cationic PAM demonstrates strong tolerance, functioning effectively across a wide pH range of 3–12 (acid and alkali resistant) and a temperature range of -5°C to 90°C. This makes it adaptable for use in mine wastewater, papermaking black liquor, printing and dyeing wastewater, and oilfield reinjection water.

Q What industries can cationic PAM be applied to?

Cationic PAM has broad industrial applications including municipal sewage treatment, industrial wastewater treatment (steel mills, electroplating plants, paper mills), oilfield exploitation for improving oil recovery, paper and textile manufacturing for enhancing strength and reducing fiber loss, and agricultural soil improvement to prevent erosion and enhance water retention.

Q What packaging options are available for cationic PAM?

Cationic PAM is available in 25kg woven bags lined with plastic inner bags, as well as 1-ton jumbo bags. Custom English labeling and customer logo packaging are also available upon request, making it convenient for international trade and private-label requirements.

Q How should cationic PAM be stored, and what is its shelf life?

Cationic PAM should be stored in a cool, dry environment where the temperature does not exceed 35°C, and kept away from direct sunlight. When stored in its original unopened packaging under these conditions, the shelf life of the solid powder is 2 years.
