THERMOPLASTIC RESIN COMPOSITION FOR REFRIGERATOR HAVING IMPROVED CHEMICAL RESISTANCE, VACUUM FORMABILITY AND GOOD PRINTING PROPERTIES

摘要

Provided is a thermoplastic resin composition for a refrigerator which is improved in transfer characteristics and is excellent in vacuum formability, chemical resistance and thermal stability. The resin composition comprises 20-40 parts by weight of an acrylonitrile-butadiene-styrene graft copolymer resin which is prepared by emulsion graft polymerizing a monomer mixture of a cyanovinyl compound and an aromatic vinyl compound in the presence of 40-70 wt% of a rubbery polymer having an average particle size of 0.1-1 micrometer; 30-79 parts by weight of a copolymer of a cyanovinyl compound and an aromatic vinyl compound which contains 20-40 wt% of a cyanovinyl compound; and 0.5-30 parts by weight of a copolymer of a cyanovinyl compound, an acrylate compound and an aromatic vinyl compound which has a weight average molecular weight of 500,000-7,000,000.
