CONTROLLING METHOD PTC CHARACTERISTIC OF PTC COMPOSITION USING SILANE CROSSLINKING METHOD

摘要

The present invention relates to a method for controlling the PTC properties of a PTC composition by using a crosslinking method, in which a PTC composition in which conductive particles are dispersed and crosslinked in an organic polymer in which each component is grafted with a silane before blending the polyolefin, And controlling the trip time and power loss by adjusting the grafting rate of each component.;The present invention is characterized by grafting each component with a silane before blending the polyolefin, and controlling the grafting rate of each component to control the crosslinking degree for each component to control the properties of the PTC composition.
