Polyoxybenzylmethylenglycolanhydride

From Plastics Wiki, free encyclopedia

Polyoxybenzylmethylenglycolanhydride is the thermosetting phenol formaldehyde resin of bakelite, the first artificial thermosetting plastic made. Formed by the reaction under heat and pressure of phenol and formaldehyde, generally with a wood flour filler, it was used for its nonconductive and heat-resistant properties in radio and telephone casings and electrical insulators.
