Introduction to the concept of bmc mold forming processing

BMC material is the abbreviation of Bulk (Dough) moldingcompounds, that is, bulk plastic. China is often referred to as unsaturated polyester blob plastic. The key raw materials are GF (short-cut glass fiber), UP (polyurethane resin), MD (filler calcium bicarbonate) and various additives fully mixed into a mass-shaped prepreg. DMC materials were first used in Germany and the United States in the 1960s, and later gained a very large development trend in foreign countries and Japan in the 1970s and 1980s. BMC bulk molding plastic has excellent electrical equipment performance, mechanical equipment performance, temperature resistance, solvent corrosion resistance, and incorporates a variety of molding technologies to meet the performance requirements of various products. It is increasingly favored by customers.

Bulk plastic (BMC) is a thermosetting plastic, in which various plastic fillers, chemical fiber reinforcement materials, metal catalysts, thickeners and color pastes are mixed to produce an inhibited or injected adhesive ash-like composite type Material. Bulk plastics (BMC) are filled and reinforced according to the aspect ratio of polyester staple fibers. Glass fiber reinforced materials account for 10% to 30%, and the length is generally between 1/32 inch and 1/2 inch (12.5 mm).

According to the difference of the final main purpose, the configured composite material can be precisely manipulated to specifications, has excellent flame retardancy and tracking resistance, has high volume resistivity, corrosion resistance and stain resistance, and has excellent mechanical equipment performance , Low gatherability, stable color. Bulk plastics (BMC) have excellent fluidity characteristics, dielectric strength and flame retardancy, and are suitable for various applications with appropriate key points and specifications. The materials are available in 75 colors, which can be used for powder spraying and water-based paint.
