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

Cationic Polyacrylamide (CPAM) is a highly effective water-soluble polymer characterized by its positively charged molecular chain (-NH₃⁺). This innovative product engages in a unique charge adsorption + net capture interaction with negatively charged suspended solids, such as clay and colloids, as well as dissolved organic matter like humic acid and various negatively charged pollutants, including dye anions, As a result, CPAM accelerates the aggregation and removal of fine particles, establishing itself as a powerful tool for decolorization and impurity removal in applications with low turbidity but high pollution levels, such as printing and dyeing, electroplating, and chemical engineering, As a leading China supplier and factory of Cationic Polyacrylamide, we are committed to providing top-quality products that enhance water treatment processes across various industries. Choose our CPAM for reliable performance and effective pollution control

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 Adaptation 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.

Frequently Asked Questions
Q What is the ionicity range of your cationic PAM, and how do I choose the right grade?
Our cationic PAM offers an adjustable ionicity (cationic charge density) from 10% to 80%. 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 suitable. Our technical team can assist you in selecting the optimal grade based on your specific wastewater characteristics.
Q How long does the powder PAM take to dissolve, and can it be used with PAC?
The dissolution time for powder PAM is ≤ 60 minutes at room temperature. After dissolution, it produces large flocs that settle quickly — 25%–40% faster than conventional products. It works synergistically with PAC (Polyaluminum Chloride): using them in combination further enhances flocculation and settling performance, making it ideal for demanding treatment scenarios.
Q What pH and temperature ranges is this cationic PAM suitable for?
This cationic PAM demonstrates strong tolerance across a wide range of conditions. It is resistant to both acid and alkali environments (pH 3–12) and performs reliably across temperatures 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 cationic PAM commonly used in?
Cationic PAM is widely used across multiple industries, including: municipal sewage treatment (sludge dewatering and purification), industrial wastewater treatment (steel mills, electroplating plants, paper mills), oilfield exploitation (enhancing oil recovery and adjusting water injection viscosity), paper and textile manufacturing (improving paper strength and reducing fiber loss), and soil improvement (preventing erosion and enhancing water retention).
Q What packaging options are available, and can custom branding be arranged?
We offer cationic PAM in 25kg woven bags lined with plastic inner bags, as well as 1-ton jumbo bags for bulk orders. Custom packaging is available, including English labeling and logo printing, to meet your branding and export requirements.
Q What are the storage requirements and shelf life of solid powder PAM?
Solid powder PAM should be stored in a cool, dry environment with a temperature not exceeding 35°C, away from direct sunlight and moisture. When stored under these conditions in unopened packaging, the shelf life is 2 years. Once opened, it is recommended to use the product promptly and reseal the bag tightly to prevent moisture absorption and degradation.
