ETHYLENE POLYMER COMPOSITION FOR INJECTION MOLDING

摘要

PURPOSE:To provide the subject composition capable of giving injection molded products of reduced warpage; thus esp. suitable as a material for plate products such as container cover plates. CONSTITUTION:The objective polymer composition comprising (A) 100 pts.wt. of a polyethylene 0.910-0.940g/cm<3> in density and <=50g/10min in melt flow rate and/or an ethylene/vinyl ester copolymer <=50g/10min in melt flow rate and (B) 0.01-2 pts.wt. of zinc stearate. The other objective container cover plate can be obtained by injection molding of this composition.
