CPE stands for chlorinated polyethylene, which is a product of high-density polyethylene that has been chlorinated and appears as small white particles.
Performance of CPE
1. Excellent aging resistance, can be used in harsh climates and harsh environments, and has sufficient resistance to ozone.
2. Excellent flame retardancy and no spontaneous combustion.
3. Excellent low-temperature toughness, able to maintain flexibility at -20 ℃, suitable as an impact modifier for UPVC products.
4. Excellent chemical resistance, inert to most chemicals, and resistant to corrosion from various acids and bases.
5. Good processing performance, easy to process and shape.
