Black crystal electric heating film

Author:Ben Date:2011-1-19 21:42:50

Black crystal electric hearing film is such a technology that produces new electrothermal material by the union of conductive material and polyimide,which undergo complex physical and chemical reactions under high pressure and temperature.With precisely controlled surface resistance,the film resistive property is retained throughout thefilm.Thus It gives even heat coverage.Due to Its fiexibility,radioresistance and ageing resistance,this new electrothemal meterial is widely applied as heating elements for heating,heat preservation and drying etc.

Application:Heater,Heatingdevices,Health care,Agriculture facilities,Spececraft and Consumer electronics.
