POLYMER THICK FILM POSITIVE TEMPERATURE COEFFICIENT CARBON COMPOSITION |
摘要 |
The invention is directed to a polymer thick film positive temperature coefficient carbon resistor composition consisting essentially of (a) organic medium consisting of (i) a fluoropolymer resin consisting of a copolymer of vinylidene difluoride and hexafluoropropylene; and (ii) an organic solvent consisting of triethyl phosphate; and (b) conductive carbon powder. The composition may be processed at a time and temperature necessary to remove all solvent. The invention is further directed to positive temperature coefficient (PTC) circuits comprising the composition of the invention which has been dried to remove the solvent and to articles, e.g., mirror heaters and seat heaters, containing such PTC circuits as well as a method for making such PTC circuits. |
