Abstract:
A method of making a thermally conductive article having an integrated thermally conductive surface, comprising the steps of:a) providing two molding members in an aligned relationship, wherein a mold cavity is located between the members, b) injecting a first molten thermally conductive composition comprising a non-elastomer polymer matrix and thermally conductive filler material into the cavity to form a molded body, c) removing a molding member to expose a surface of the molded body, d) injecting a second molten thermally conductive composition comprising an elastomer polymer matrix and thermally conductive filler material onto the exposed surface of the molded body, e) cooling the compositions to form an article having an integrated thermally conductive surface, and f) removing the article from the mold.
