YUPLENE® BX3900 Polypropylene Impact Copolymer SK Global Chemical
Y
UPLENE BX3900 is a high crystalline propylene impact copolymer designed for injection
molding
applications. YUPLENE BX3900 has excellent properties in stiffness, flow,
mechanical properties, heat
resistance and impact strength, which make YUPLENE BX3900
suitable for auto parts, electric
appliances, large size containers, thin wall and very high
spe
ed injection applications. This is not a
chemical cracked grade so it is free from surface
gas mark. YUPLENE BX3900 can reduce various
injection problems such as surface trouble,
shrink, warpage etc. and reduce the cycle time of injection
molding due to ra
pid
crystallization.
