抗沖擊共聚聚丙烯
Lotte Chemical Corporation
產(chǎn)品說明:
JM-370UN is high impact block copolymer which has more ethylene contents than normal block copolymer.This grade is designed to be processed in conventional Injection molding equipment.
JM-370UN shows high melt flow has medium impact resistance and high strength and stiffness.
JM-370UN has good physical property balance and weathering resistance.
This grade is appropriate for energy saving and multi-cavity injection molding.
