Industrial Phenolic Laminates are made by applying heat and pressure to layers of paper, canvas, linen or glass cloth impregnated with synthetic themosetting resins. When heat and pressure are applied to the layers, a chemical reaction (polymerization) transforms the separate layers into a single laminated material with a "set" shape that cannot be softened again - therefore, these materials are called "thermosets". A variety of resin types and cloth materials can be used to manufacturemore
