ELECTRICAL DEVICE CONTAINING POSITIVE TEMPERATURE COEFFICIENT RESISTOR COMPOSITION AND METHOD OF MANUFACTURING THE DEVICE

摘要

A positive temperature coefficient (PTC) resistor composition, comprising: (a) about 3% to about 75% by weight of a binder resin, (b) about 2% to about 70% by weight of a temperature activatable semicrystalline polymer, which is a thermopl astic elastomer (TPE) that melts at a relatively narrow temperature range to change fr om a crystalline state to an amorphous state, (c) about 10% to about 80% by weight of an electrically conductive material in finely particulated form selected from the g roup consisting of silver, graphite, graphite/carbon, nickel, copper, silver coated c opper, and aluminum, (d) about 0.01% to about 80% by weight of solvent material for the composition.
