DMC (BMC) Materials

DMC(BMC) Material, that is bulk(dough) molding compounds, Main raw material is:chopped glass fiber、unsaturated polyester(UP)、MD(Filler))and other auxiliaries;through well blended,made into bulk(dough) molding presoak material. Bulk(dough) molding compounds have excellent electric properties, mechanical properties, heat resistance, chemical-resistance;It’s suitable for a variety of processes and can meet the demands of various products on performance.

It can be used to make the machine parts such as transmission components, Inlet pipe, tire valve cap, bumper;and also can be widely used in aviation, construction, furniture, which have demands of earthquake resistant, flame retardant, beautiful, durable,etc.

Size:1000x2000mm;1250x2000mm;1250x2500mm

Thickness:2~50mm

The size of other parts can be customized
