Our phenolic sheet and plate is a hard, dense thermoset material made by applying heat and pressure to layers of paper or fabric impregnated with resin. This material is widely used for electrical insulation, terminal boards, and mechanical wear parts in heavy machinery. It offers excellent resistance to heat and chemicals, making it ideal for the power generation and manufacturing sectors. Phenolic is a favorite for its high dielectric strength and its ability to maintain structural integrity under physical load.
