Process for forming a crosslinked polyvinyl chloride foam and product thereof by means of radiation crosslinking

摘要

Crosslinked polyvinyl chloride foams are formed by first expanding a polyvinyl chloride containing plastisol comprising a blowing agent, and a reactive crosslinking plasticizer to form a foamed composition and then subjecting the foamed composition to irradiation to crosslink the foamed composition via the crosslinking plasticizer.
