Abstract

Process for producing, by melt injection, expanded polyvinyl chloride articles, characterized in that the paste of p.c.v. For injection contains, in addition to the usual additions of plasticizers and stabilizers, an addition of blowing agent not exceeding 1.5 parts by weight relative to 100 parts by weight of polyvinyl chloride.
