ABSTRACT:
The conductive polymer composition used in an over-current protection device blends a polymer substrate (for instance, PVDF) with the polyolefin and the conductive filler of carbon black alike. The polyolefin comprises of two monomers along the carbon chain to form its principal chemical structure. The first monomer includes four hydrogen atoms to bond with the carbon chain, and the second monomer includes at least one fluorine atom and at least one non-fluorine halogen atom. The non-fluorine halogen atom may be selected from chlorine, bromine and iodine elements.
