FOAMABLE CHLORINATED VINYL CHLORIDE-BASED RESIN PARTICLES, FOAMED PARTICLES THEREOF, CHLORINATED VINYL CHLORIDE-BASED RESIN FOAM MOLDED ARTICLE, AND METHOD FOR PRODUCING FOAMABLE CHLORINATED VINYL CHLORIDE RESIN PARTICLES

摘要

The purpose of one embodiment of the present invention is to provide foamable chlorinated vinyl chloride-based resin particles from which it is possible to obtain a chlorinated vinyl chloride-based resin foam molded article achieving both high foaming ratio and excellent surface appearance. The foamable chlorinated vinyl chloride-based resin particles have a porosity of 5.5 (ml/100g) or less.
