RESIN COMPOSITION WITH AN ANTI-SCRATCH AND FLAME-RETARDENT PROPETIES

摘要

PURPOSE: A resin composition is provided to secure scratch resistance and safety for fire required for housing materials of electronic products without additional processes. CONSTITUTION: A scratch resistant resin composition comprises 20-70 weight% polycarbonate resin, 15-70 weight% vinyl cyan-based aromatic vinyl compound copolymer; and 1-30 weight% graft copolymer resin polymerized with methacrylic acid ester or alkyl methacrylic acid ester, aromatic vinyl compounds, and vinylcyan-based compound to a butadiene-based rubber. The average molecular weight of the polycarbonate resin is 18,000-40,000.
