CRA Impact Modifier
Compared with acrylic impact modifiers and CPE impact modifier, CRA impact modifier has faster fusion and higher elongation at break. It can endow PVC products with better toughness than other PVC impact modifiers especially at low temperature.
Impact modifier CRA-04CP 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
