Bakelite

Bakelite is a brand named material based on the thermosetting phenol formaldehyde resin polyoxybenzylmethylenglycolanhydride, developed in 1907-1909 by Dr. Leo Baekeland. 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.
