Silicone thermal conductive sheets feature high thermal conductivity with no loss of the outstanding heat resistance and electrical insulation properties of the base material, silicone, realized by contouring to heating elements utilizing the exibility and adhesion of the sheet. The low-molecular siloxane content that causes problems such as contact faults in electronic devices is no more than 70ppm, making it possible to use the product near contact points in devices such as switches.
