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.

Abstract: A foamed polymer composition includes a matrix polymer component, and from 0.01 wt % to 2 wt %, based on the weight of the polymer composition, of a nanostructured fluoropolymer, a nanostructured fluoropolymer encapsulated by an encapsulating polymer, or a combination thereof. The matrix polymer component includes polybutylene terephthalate (PBT), polyetherimide (PEI), polyethylene terephthalate (PET), polycarbonate (PC), poly(p-phenylene oxide) (PPO), polystyrene (PS), polyphenylene sulfide (PPS), polypropylene (PP), polyamide (PA), polytrimethylene terephthalate (PTT), polyethylene naphthalate (PEN), polybutylene naphthalate (PBN), copolymers thereof, or a combination thereof. Methods for forming foamed polymer compositions, including core-back molding methods and extrusion foaming methods, are also described.
