Its main raw materials are the pellet prepreg formed by fully mixing GF (chopped glass fiber), UP (unsaturated resin), MD (filler calcium carbonate) and various additives. BMC materials were first applied in the former West Germany and Britain in the 1960s, and then developed greatly in the United States and Japan in the 1970s and 1980s respectively. Because BMC bulk molding compound has excellent electrical properties, mechanical properties, heat resistance, chemical corrosion resistance, and is suitable for various molding processes, which can meet the performance requirements of various products, it is more and more popular with users.

Features: good softness, no fracture at low temperature, no deformation at high temperature
