PP-CP-SK CHEMICAL-BM3900
YUPLENE BM3900 is a high crystalline propylene impact copolymer designed for injection molding applications. YUPLENE BM3900 has excellent properties in stiffness, flow, mechanical
properties, heat resistance and impact strength, which make YUPLENE BM3900 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 BM3900 can reduce various injection problems such as surface trouble, shrink, warpage etc. and reduce the cycle time of injection molding due to rapid crystallization. Especially, YUPLENE BM3900 has low shrinkage value and excellent dimensional stability.
Application
Injection Molding / industrial parts for electronic, automobile applications, large container
