BMC molding compound is an abbreviation of Bulk (Dough) molding compound, that is, a bulk molding compound. BMC molding compound is often referred to as unsaturated polyester bulk molding compound in China. The main raw material is a dough-like prepreg which is sufficiently mixed with GF (short-cut glass fiber), UP (unsaturated resin), MD (filler), and various additives. DMC materials were first applied in the former West Germany and the United Kingdom in the 1960s, and then in the United States and Japan in the 1970s and 1980s. Because BMC bulk molding compound has excellent electrical properties, mechanical properties, heat resistance, chemical resistance, and adapt to various molding processes, it can meet the performance requirements of various products, so it is more and more popular by users.

Application of BMC molding compound

First, electrical components Low-voltage categories: RT series, isolating switches, air switches, switchboards, meter housings, etc.;
High-voltage type: insulator, insulation cover, arc-extinguishing cover, closed lead plate, ZW, ZN vacuum series.

Second, auto parts lights, that is, Japanese headlight reflectors are almost all made with DMC;
Automobile igniter, separation disc and trim board, speaker box, etc.;

Third, the motor components Air conditioning motor, motor shaft, coil bobbin, electric and pneumatic components.

Fourth, daily necessities Microwave tableware, electric iron shell and so on.

Packaging, transportation, storage

BMC series molding compound is packaged in a composite film bag, each bag is 25 kg, and then packed into a carton after being wrapped;
Beware of heavy pressure, heat and damage to packaging during transportation;
The storage period is in the dry warehouse with the temperature below 25 and avoiding sunlight. The production date is three months from the date of production.
