More Information
Summary:An electrically conductive high-molecular composition with positive temp coefficient (PTC) contains electrically conductive particles, which may be carbon black with developed or non-developed graphite crystal structure, and high-molecular material, which may be the branched polyolefine with molecular weight less than 2.5 and fusion heat higher than 50 J/g. Said composition can be mixed with the high-molecular material with high adhesion to metal electrode in order to prevent the metal electrode from being dropped due to temp variation.
