Product Details

Phenolic Sheet, Bakelite Sheet, Cotton Sheet, Insulation Sheet for High Voltage Application

Bakelite is called phenolic paper laminated sheet. A hard, dense material made by applying heat and pressure to layers of paper or glass cloth impregnated with phenolic resin. These layers of laminations are usually of cellulose paper, cotton fabrics, synthetic yarn fabrics, glass fabrics or unwoven fabrics. When heat and pressure are applied to the layers, a chemical reaction (polymerization) transforms the layers into a high-pressure thermosetting industrial laminated plastic.
