BMC is the abbreviation of bulk molding compound in English, and its Chinese name is bulk molding compound. BMC is a semi dry molding intermediate material for manufacturing glass fiber reinforced thermosetting products. It is made of unsaturated polyester resin, low shrinkage / low profile additives, initiator, internal mold release agent, mineral filler, etc., which are pre mixed into a paste, then thickener, colorant, etc. are added, and glass fibers of different lengths are stirred in a special kettle for thickening, Finally, the agglomerated intermediate material can be used for molding and injection molding.
According to different final application fields, the prepared composite can accurately control the size, has good flame retardancy and resistance to electric trace, has high dielectric strength, corrosion resistance and pollution resistance, excellent mechanical properties, low shrinkage and stable color. Due to its excellent flow characteristics, insulation and flame retardancy, BMC is very suitable for various applications requiring precise details and dimensions. The materials are available in 75 colors and can withstand powder spraying or waterborne coatings.
