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 AIM and CPE 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.
