Heat-Away™ 640 is a single-part, 100% solids, copper-filled, thermally conductive, silicone grease used in heat transfer applications from –60 to 550 ºF (-51 to 288 ºC). Heat-Away™ 640 is formulated as a thick paste that will not flow after application and the viscosity remains stable over the entire temperature range. The thermal conductivity is 4.68 W/m-K.
Heat-Away™ 640 is used to improve the thermal transfer between heaters and process vessels and various heat sinks used in heat exchangers in electrical and electronic applications. Heat-Away™ 640 is supplied in standard pint, quart, gallon and five gallon containers from stock.
