Precautions when choosing chlorinated polyethylene

Precautions when choosing chlorinated polyethylene:
CPE chlorinated polyethylene is widely used in refrigerator magnetic strips, PVC door and window profiles, pipe sheets, fittings, blinds, wire and cable sheaths, waterproof rolls, flame-retardant conveyor joints, and rubber hoses. Tires, film, etc.
Chlorinated polyethylene (CPE) is a crystalline or micro crystalline white fine granular elastic material made by replacing hydrogen atoms in special high-density polyethylene with chlorine atoms. It has good flexibility, low brittleness temperature, good weather resistance, aging resistance, chemical resistance, ozone resistance, flame retardancy and other characteristics. It is compatible with various plastics and rubbers and has excellent filling performance. According to different product performance, CPE chlorinated polyethylene can be used as an impact modifier, plastic modifier compatibilizer, and synthetic special rubber.

Precautions for purchasing include:
1. When choosing chlorinated polyethylene (CPE), attention should be paid to the appropriate grade. Different grades have different chlorine content and performance. For example, CPE135A with a chlorine content of 35% should be selected as a PVC impact modifier.
2. To ensure product quality, it is necessary to choose products from reputable manufacturers.
3. To verify whether the product is pure CPE, because many low-priced CPE sold by merchants are impure and will add some calcium powder to reduce costs. As long as it is heated to 150 ℃ in an oven, if it gradually turns yellow, it must be due to the addition of calcium powder.
