BAKELITE SHEETS (PHENOLIC LAMINATES)
Bakelite (Phenolic Laminates) is one of the earliest thermosetting plastics ever invented. It is manufactured by impregnating layers of paper or fabric with phenolic resin and curing them under heat and high pressure. The result is a rigid, tough, and durable laminate with excellent electrical insulation, good heat resistance, and strong mechanical properties.
Today, Bakelite Sheets & Rods are widely used in electrical, electronic, industrial, and consumer applications.
Main Benefits
