impact modifier CRA
Character:
Impact modifier CRA-03CA is a grafted copolymer of light-chlorinated HDPE and acrylate with structure of CPE-grafted-polyacrylate. Compared to CPE, CRA has faster fusion and higher elongation rate at break. Its main function is to enhance the impact strength under low temperature and to promote the fusion property of PVC blend. It can bring the best toughness to PVC products than other PVC additives.
Product benefits
● Excellent elongation rate at break and toughness
● Excellent corner welding strength
● Excellent impact strength under low temperature
● Fast fusion property
● Better weather-resistance
● Good surface glossiness and excellent processability
