Production method hume pipe cushion material and a method of manufacturing the low-magnification molding expandable polystyrene resin particles, low-magnification expanded particles, and low magnification molded foam, of Hume pipe cushion material and low magnification molded foam

摘要

Is made of polystyrene resin containing a blowing agent, per 100 parts by weight of expandable polystyrene resin particles is in the range of 300μm~2500μm, and 0.02 to 2.5 parts by weight of a higher fatty acid amide, an average particle size of fine a low magnification molding expandable polystyrene resin particles characterized by comprising by coating the particle surface in combination with 0.02 to 2.5 parts by weight of fatty acid triglyceride, and low so as to low magnification foamed particles providing a fold-expanded particles, a low-magnification expanded molded article obtained by in-mold foam molding this low magnification foamed particles. In accordance with the present invention, fusion rate of the expanded particles of the foamed molded product obtained by in-mold foam molding is high, and high elongation of the foamed particles, and produce a low magnification expansion-molded article having high compressive strength and bending strength Suitable low magnification molding expandable polystyrene resin particles can be provided to.
