抗沖擊共聚聚丙烯
SK Global Chemical
產(chǎn)品說明:
YUPLENE BX3820 is a high crystalline propylene impact copolymer designed for injection molding applications. YUPLENE BX3820 has excellent properties in stiffness, flow, mechanical properties, heat resistance and impact strength, which make YUPLENE BX3820 suitable for auto parts, electric appliances, large size containers, thin wall and very high speed injection applications. This is not a chemical cracked grade so it is free from surface gas mark. YUPLENE BX3820 can reduce various injection problems such as surface trouble, shrink, warpage etc. and reduce the cycle time of injection molding due to rapid crystallization.
