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. |
