Description for SMC:
Sheet molding compound (SMC) compositions are complex mixtures of resins and fiberglass with various ingredients (fillers, catalysts, thickeners), all of which influence important property and processing characteristics. we mainly use unsaturated polyesters and vinyl esters as being the major systems used.
SMC formula can be customized according to the finished products' requirements to achieve the special functions: such as a typical low profile SMC composition useful for molding automative body panels with quality surface, polished surface building materials like sanitary products, flame retardant electronic products or high strength products so on.
2 production lines with the capacity around 25000tons/year, the stable quality and the best service helped us to develop many customers in different field from different countries.
For Battery pack covers,the fire retardancy meets the UL-94,5VA;2.5mm,V0;3.0mm,V0
