Bakelite is a heat-resistant, thermosetting, chemically stable resin (polyoxybenzylmethylenglycolanhydride, the first
plastic), invented about 1907-1909 by Dr. [Leo Baekeland]
?, a American chemist of Belgian origin. It is formed by combining
phenol and formaldehyde
? under heat and pressure. Radios, telephones and electrical insulators were made of Bakelite in the past due to its insulating and heat-resistant properties.
