Bakelite. Employed chiefly as an electric insulator, Bakelite has numerous industrial uses, including the manufacture of phonograph records, machinery, and even buttons, pipe stems, and billiard balls. A heat-resistant, synthetic resin or plastic, valuable as a nonconductor of electricity, it is prepared by the chemical interaction of phenolic substances and aldehydes.
