China Cationic Polyacrylamide (CPAM) Suppliers & Factory in China for Effective Decolorization and Impurity Removal Manufacturers, Suppliers

Cationic Polyacrylamide (CPAM) is a highly effective water-soluble polymer known for its positively charged molecular chain (-NH₃⁺). This innovative product functions through the charge adsorption + net capture mechanism, effectively interacting with negatively charged suspended solids like clay and colloids, dissolved organic matter (such as humic acid), and negatively charged pollutants including dye anions. As a result, CPAM rapidly aggregates and removes fine particles, making it an essential solution for decolorization and impurity removal. Particularly beneficial in low turbidity and high pollution environments, Cationic Polyacrylamide is widely used in industries such as printing and dyeing, electroplating, and chemical engineering. As a trusted product offered by reputable suppliers and manufacturers in China, CPAM stands out as a powerful tool for achieving cleaner water and improved processing efficiency

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 Cationic PAM

• 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.

Fast Dissolving Cationic Polyacrylamide

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 ionicity range of this cationic PAM, and how do I choose the right grade?
The ionicity (cationic charge density) 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 ionicity grade (50%–80%) is more effective.
Q 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, it forms large flocs that settle 25%–40% faster than conventional products. It performs even better when used in combination with PAC (Polyaluminum Chloride), making the two a highly recommended pairing for enhanced flocculation efficiency.
Q What pH and temperature conditions is this PAM suitable for?
This cationic PAM offers strong tolerance across a wide range of conditions. It is resistant to acid and alkali environments with a pH range of 3–12, and is temperature-resistant from -5°C to 90°C. This makes it suitable for diverse industrial applications including mine wastewater, papermaking black liquor, printing and dyeing wastewater, and oilfield reinjection water.
Q What industries and applications is this cationic PAM designed for?
This product is widely used across multiple industries, 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).
Q What packaging options are available, and can custom branding be arranged?
The product is available in 25kg woven bags (lined with inner plastic bags) or 1-ton jumbo bags. Custom English labeling and customer logo packaging are available upon request, making it convenient for distributors and OEM buyers worldwide.
Q What are the storage requirements and shelf life for this product?
The product should be stored in a cool, dry place at a temperature of ≤ 35°C, away from direct sunlight and moisture. When stored in its original unopened packaging under these conditions, the shelf life of the solid powder is 2 years.
