LTP 8100 serials is reinforced composite materials with high performance based on polyolefin and PPS, and are extensively applied in injection mold to structure and parts of machine, electric appliance and automobiles. It is used to replace materials of PA PBT (PET), PPO (PPE), and PC/ABS serial.
The LTP 8100 serials materials have the characteristics of high impact strength, high dimensional stability and low moisture absorption.
