Abstract
A PTC circuit protection device has a resistivity at 20.degree. C. of less than 10 ohm-cm and is made from a PTC polymer composition that contains: 40-70 vol % of a non-cross-linked polyvinylidene fluoride (PVDF) or a cross-linked polyvinylidene fluoride formed by cross-linking the non-cross-linked polyvinylidene fluoride by irradiation to a dosage less than 8 Mrads; and 30-60 vol % of a particulate conductive filler. The non-cross-linked polyvinylidene fluoride has a melting flow rate (MFR) of less than 120 g/10 min.
