Ethylene Vinyl Acetate Based Polymer Foams with Low Density, Injection Preparation Method Thereof and a Material for Medical and Health-Care use

摘要

The present invention relates to ethylene vinyl acetate based polymer foams with low density and superior injection molding characteristics, a preparation method thereof and a material for medical and health-care use using the same, more particularly to ethylene vinyl acetate based polymer foams with low density prepared by blending, masticating, pelletizing and foaming a matrix resin comprising ethylene vinyl acetate (EVA) resin and ethylene methyl acrylate (EMA) resin under specific condition, which has low density and superior injection molding characteristics and improved biocompatibility to human body, making them a useful environment-friendly material and particularly applicable to medical or health-care use, a preparation method thereof and a material for medical and health-care use using the same.
