Abstract: A polymer foam composition includes: from about 5 wt. % to about 84 wt. % of a polymer base resin; from about 15 wt. % to about 70 wt. % of a thermally conductive filler having an aspect ratio greater than 1:1; from about 0.01 to about 5 wt. % of a nanostructured fluoropolymer; and from about 0.01 wt. % to about 2 wt. % of a foaming agent. The polymer foam composition is formed from a core-back process and exhibits a thermal conductivity of at least 1.5 W/mK when tested in accordance with ISO 22007-2. Articles including the polymer foam composition are further described; in one aspect the article is a heat exchanger. Methods of forming the polymer foam composition are also described.

Abstract: A method for forming foamed beads includes: saturating pellets with a blowing agent to form saturated pellets; and depressurizing the saturated pellets in a pressure vessel to form the foamed beads. The pellets include: a matrix polymer component, and from 0.01 wt% to 2 wt%, based on the weight of the pellets, of a nanostructured fluoropolymer, a nanostructured fluoropolymer encapsulated by an encapsulating polymer, or a combination thereof.
