Bakelite has a number of important properties. It can be molded very quickly, decreasing production time. Moldings are smooth, retain their shape and are resistant to heat, scratches, and destructive solvents. It is also resistant to electricity, and prized for its low conductivity. It is not flexible. Phenolic resin … See more Bakelite , formally Polyoxybenzylmethyleneglycolanhydride, is a thermosetting phenol formaldehyde resin, formed from a condensation reaction of phenol with formaldehyde. The first plastic made from … See more Baekeland was already wealthy due to his invention of Velox photographic paper when he began to investigate the reactions of phenol See more The characteristics of Bakelite made it particularly suitable as a molding compound, an adhesive or binding agent, a varnish, and a protective coating.
