Cancle
Compound
DMC/BMC is manufactured under special production formula and in the professional equipment by mixing the unsaturated polyester glass resin, fiber glass, fillings, pigment, and other chemical agents, etc. It possesses good insulating property, high mechanical property, thermal resistance, fire retardant, corrosion stability, and especially the moulding property such as good fluidity, lower moulding pressure and temperature, short moulding time. DMC/BMC is the best moulding material for complex, thin wall and big moulding parts.
