Acrylic Chlorinated Polyethylene CPA-90

Quantity:

Acrylic Chlorinated polyethylene CPA-90


Description

CPA-90 is developed by Shandong Polymer Additives Co., Ltd’s R&D Center. Compared with CPE, it endows PVC products with much higher elongation at break and excellent toughness at low temperature. It can replace CPE and processing aid in the formulation.

Key property

● Excellent impact strength under low temperature

● Excellent toughness and hardness for PVC products.
● Excellent corner welding strength for PVC profile
● Excellent nail-force for WPC.
● Better weather-resistance
● Better surface glossiness for PVC finished products
