Phenolics is an industrial thermoset laminate and is generally stronger than thermoplastic materials at elevated temperatures up to 130 degrees celcius. It is a hard, dense engineering plastic manufactured by applying heat and pressure to layers of resin-impregnated paper sheet or cotton fabric. During the heat and pressure process, polymerization occurs and this transforms the layers into a high-pressure thermoset laminate.
Various brands of Phenolics are available; the main brands being Thiolyte and Tufnol.
