    Abstract: A process for making a multilayered article, the process comprising the steps of: (A) Providing a mold comprising: (1) A mold housing comprising (a) at least one injection port, and (b) defining a mold cavity within which are positioned two deformable, pre-molded polymeric sheets; and (2) A removable, hollow core equipped with at least one vent, the removable, hollow core positioned between and space apart from the two polymeric sheets; (B) injecting under high pressure a viscous, crosslinkable, thermoplastic polymer into the mold cavity between the two polymeric sheets and around the removable core, (C) Drawing a vacuum on the mold cavity through both the vent in the mold housing and the vent in the removable, hollow core before, during and/or after the polymer has been injected into the mold; (D) Forming a less than fully cured multilayered article in the mold cavity; and (E) Removing the less than fully cured multilayer article from the mold cavity.

    Abstract: Thermally conductive materials comprising a non-polar elastomer, a polar elastomer, and a thermally conductive filler. The polar elastomer and non-polar elastomer are sufficiently immiscible to form a polar elastomer phase and a non-polar elastomer phase. The thermally conductive filler is concentrated in an amount of at least 60 volume percent of the total filler amount in either the non-polar elastomer phase or the polar elastomer phase. The thermally conductive material has a tensile modulus less than 200 MPa. Such thermally conductive materials can be employed in a variety of articles of manufacture as thermal interface materials.
