SARCON® GAR Highly Thermal Conductivity and Electricity Insulation Glass cloth reinforcement.


・ SARCON GAR is Fujipoly’s originally developed High Heat Conductive Silicone Rubber.
・ SARCON GAR has excellent insulative and highly heat conductive 3.0W/m-K silicone material.
・ Usable Over a Wide Temperture Range. (Recommended Operating Temp.: –40 to +150°C / –40 to +302°F)
・ UL94 V-0 equivalent
・ Physical characteristics are much improved with Glass Fabric reinforcement as the base material.
・ SARCON GAR is available with a PSA (Silicone Pressure Sensitive Adhesive) mounting option.
