Abstract
The present invention relates to a positive temperature coefficient composition comprising a semi-crystalline material, at least one binder, from 0.5 to 9.5% by weight of an electronically conductive material and a solvent. Furthermore, the present invention relates to use of a positive temperature coefficient composition according to the present invention in heating elements and sensors. A positive temperature coefficient composition according to the present invention provides low and stable resistance till self-regulating temperature, which allows fast heating of the heating element. Furthermore, the positive temperature coefficient composition according to the present invention has high PTC ration and therefore, has higher safety and more power can be applied to the heating element.
