Method of making a laminate comprising a conductive polymer composition

摘要

A method of making a laminate from a conductive polymer composition in which a particulate filler is dispersed in a polymeric component. The method comprises the following steps conducted sequentially in a single continuous procedure: (A) loading the polymeric component and the conductive filler into a mixing apparatus; (B) mixing the polymeric component and the conductive filler to form a molten mixture; (C) transporting the mixture from the mixing apparatus through a die; (D) forming a polymeric sheet; and (E) attaching metal foil to a least one side of the sheet to form a laminate. The laminate can be used to prepare circuit protection devices or heaters.
