THERMOPLASTIC RESIN FOAM

摘要

PURPOSE:To provide a thermoplastic resin foam having fine cells and high impact strength without any surface unevennesses by visual observation. CONSTITUTION:The thermoplastic resin foam is obtained by mixing and dispersing 1-40wt.% polyethylene terephthalate resin in a polycarbonate resin, using the resultant polymer alloy as an expansion base material and making includ bubbles having 5mum or smaller average bubble diameter therein.
