Pptc material with one-step hot application process

Abstract

A method for preparing a preparing a polymeric positive temperature coefficient (PPTC) compound and conformally applying such compound to a substrate in accordance with an embodiment of the present disclosure may include preparing and mixing raw materials to form a PPTC mixture, processing the PPTC mixture through polymer compounding equipment, wherein the PPTC mixture is heated and is extruded as a PPTC compound, performing a beaming process on the polymer compound to establish crosslinking between polymer chains in the PPTC compound, and applying the PPTC compound to a substrate using a hot application process wherein the PPTC compound is heated and is conformally applied to a surface of the substrate.
