Production process for PCT-polymer product

摘要

The method is provided for forming a form product from a PTC-polymer material consisting of a conducting filler material and optionally further filler material in a matrix of polymer material. During the forming process the PTC-polymer material is deformed my means of a tool under heat and pressure. Hereby the PTC polymer material is heated to an absolute temperarture of at most 1,1 x TS, TS being the absolute melting temperature of said matrix polymer material. PTC-polymer products made according to this method comprise a very stable tripping behaviour. <IMAGE>
