CPE135A Impact Modifier for Rigid PVC Products - Quality Supplier from China Factory
Products Description
Chlorinated polyethylene is a saturated polymer material, the appearance is white powder, it is non-toxic and tasteless, it has excellent weather resistance, ozone resistance, chemical resistance and aging resistance, and it has good oil resistance, flame retardancy and coloring performance. Good toughness (still flexible at -30C), good compatibility with other polymer materials, and high decomposition temperature.
CPE-135A contains almost no crystals and has excellent flame retardancy, electrical insulation, chemical resistance, oil resistance and water resistance; it has good compatibility with PVC, Cr, NBR, etc. It can also be used as a flame retardant for ABS products, wire and electrical enclosures, flexible PVC foam materials, modifiers for special synthetic rubbers, general synthetic rubbers, and plasticizers for PVC and other plastics. Compared with ordinary chlorinated polyethylene on the market, Bontecn chlorinated polyethylene has the characteristics of low glass transition temperature, superior processing performance and high elongation at break. It is a kind of high-performance, high-quality special rubber. It can be used alone or in combination with ethylene-propylene rubber, butadiene-propylene rubber and chlorostyrene rubber to produce rubber products. The products produced have a long service life and are UV resistant. No matter how harsh the environment and climate, they can maintain the inherent properties of rubber for a long time.

Frequently Asked Questions
1. What is Chlorinated Polyethylene (CPE)?
Chlorinated polyethylene (CPE) is a saturated polymer material that appears as a non-toxic, tasteless white powder. It exhibits excellent weather resistance, ozone resistance, chemical resistance, aging resistance, good oil resistance, flame retardancy, and low-temperature toughness down to -30°C.
2. What are the key properties of CPE-135A?
CPE-135A contains almost no crystals and features excellent flame retardancy, electrical insulation, chemical resistance, oil resistance, and water resistance. It also provides outstanding elongation at break (>800%) and excellent powder fluidity.
3. In which fields is CPE-135A mainly applied?
It is widely used in rigid PVC products such as profiles, pipes, fittings, plates, and wires to increase toughness and impact strength. It also serves as a flame retardant for ABS products, wire/electrical enclosures, flexible PVC foam materials, and as a modifier for synthetic rubbers.
4. What makes Bontecn CPE different from ordinary CPE on the market?
Compared to ordinary options, Bontecn chlorinated polyethylene features a lower glass transition temperature, superior processing performance, and high elongation at break, making it a high-performance, high-quality special rubber with long-term UV and weather resistance.
5. Can CPE-135A be used with other rubber materials?
Yes, it has good compatibility with PVC, Cr, NBR, etc. It can be used alone or combined with ethylene-propylene rubber, butadiene-propylene rubber, and chlorostyrene rubber to produce durable rubber products with an extended service life.
