团状模塑料(BMC模塑料)是一种热固性塑料，其中混合了各种惰性填料、纤维增强材料、催化剂、稳定剂和颜料，形成一种用于压塑或注塑的胶粘“油灰状”复合材料。团状模塑料(BMC模塑料)通过短纤维进行高度填充和增强，玻璃纤维增强材料占10%至30%，长度通常在1/32英寸至1/2英寸(12.5mm)之间。

Mass mold plastic (BMC mold plastic) is a kind of thermosetting plastic, which is mixed with various inert fillers, fiber reinforced materials, catalysts, stabilizers and pigments, forming a kind of sticky "putty" composite material used for plastic or injection molding. Mass mold plastics (BMC moulds) are highly filled and reinforced through short fibers, and glass fiber reinforced materials account for 10% to 30%, and the length is usually between 1/32 inches and 1/2 inches (12.5mm).

根据不同的最终应用领域，配制的复合材料可精确控制尺寸，阻燃性和抗电痕性良好，具有很高的介电强度、耐腐蚀性和耐污性，机械性能卓越，收缩性低且色泽稳定。团状模塑料(BMC模塑料)的流动特性和绝缘及阻燃性极好，对于细节和尺寸要求精确的各种应用非常适用。材料有75种颜色可供选择，能抵受粉剂喷涂或水性涂料。

BMC模塑料(DMC)的比重较大，在1.3-2.1之间;制品外观光亮，手感好，有硬而厚重的感觉;用火加热会产生很多油烟，并有苯乙烯气味;某些品种的BMC模塑料(DMC)难燃，但某些品种又极易燃烧，燃烧后留下无机物质。

BMC mold plastic (DMC) has a large proportion of 1.3-2.1; the product has a bright appearance, a good feel, a hard and heavy feeling; the heat will produce a lot of oil smoke, and the smell of styrene; some varieties of BMC moulded plastic (DMC) is difficult to burn, but some varieties are very easy to burn and leave the inorganic material after burning.

BMC模塑料(DMC)的线膨胀系数是(1.3-3.5)×10-5K-1，比一般的热塑性塑料小，因而使得BMC模塑料(DMC)具有很高的尺寸稳定性和尺寸精度。温度对BMC模塑料(DMC)的尺寸稳定性影响很小，但湿度的影响则较严重，BMC模塑料吸湿后会膨胀。BMC模塑料(DMC)的线膨胀系数和钢、铝的很接近，因此可以和其进行复合。

The linear expansion coefficient of BMC mold plastic (DMC) is (1.3-3.5) x 10-5K-1, which is smaller than the ordinary thermoplastic plastic, so that the BMC mold plastic (DMC) has a very high dimensional stability and dimensional accuracy. Temperature has little effect on dimensional stability of BMC molding compounds (DMC), but humidity is more serious. BMC moulded plastics will expand after moisture absorption. The linear expansion coefficient of BMC molding compound (DMC) is very close to that of steel and aluminum, so it can be combined with it.
