SMC是一种夹芯的模压用原材料，上下两面用聚乙烯薄膜覆盖的片状材料，厚度在1.5mm-3.5mm，宽度500mm-1400mm，成卷供应或箱式吨位包装。使用时，经裁剪、称重、揭去薄膜，放入到已升温模具中，加压保压后脱模得到成品。

SMC复合材料及其SMC模压制品，具有优异的电绝缘性能、机械性能、热稳定性、耐化学防腐性。

SMC is a type of compression material for the compression of a type of sandwich, and the sheet material covered by polyethylene film is covered in the thickness of 1.5mm-3.5mmmm, width 500mm-1400mmmm, coil supply or box tonnage packing. When used, the film is cut, weighed, and put into the heating mold, and the pressure and pressure is removed and the finished product is obtained.

SMC composite materials and their SMC moulded products, have excellent electrical insulation, mechanical energy, thermal stability and chemical corrosion resistance.
