High temperature resistance, high thermal conductivity, good insulation performance, high temperature resistant fiber reinforced material, and metal heating film circuit are all components of the silicone heating sheet, a soft electric heating element. A silicone glass fiber fabric is created by pressing two sheets of silicone and two sheets of glass fiber cloth together. Due to its thinness (the industry norm is 1.5 mm), it is soft and can make total contact with the heated object.
