PHENOL RESIN MOLDING MATERIAL AND PHENOL RESIN MOLDED ARTICLE

摘要

Disclosed is a phenol resin molding material which has improved storage stability, kneading stability and moldability before curing, while exhibiting improved heat resistance, dimensional accuracy and dimensional stability after curing. The phenol resin molding material contains a novolac phenol resin, a polyvinyl acetate-modified novolac phenol resin, and a filler.  Silica is contained therein as the filler in an amount of 75-90% by mass relative to the total amount of the phenol resin molding material.
