Abstract (en)
[origin: WO9103822A1] A melt-extrudable conductive polymer composition which contains a polymer, a particulate conductive filler and a particulate non conductive filler. When a standard strip heater is made from the composition and tested in a UL VW-1 test, it has comparable performance to a heater made from a second composition which is the same as the composition but which does not contain the non conductive filler. When tested in a standard arcing fault test, the standard heater will trip a fuse in less time than is required by the second heater, i.e. in less than 30 seconds. A preferred nonconductive filler is Sb2O3.
