TC board (Kyocera Corporation) is an insulating board made by heating and pressurizing a special unsaturated polyester resin (premix) and has excellent tracking resistance, arc resistance, heat resistance, and acid resistance. It is significantly cheaper than glass cloth epoxy resin laminate (EL-GEM).
