    Abstract: A blowing agent blend for making thermoplastic polymer foams includes methyl formate. The blowing agent blend can further comprise at least one co-blowing agent. The co-blowing agent is either a physical co-blowing agent (e.g. an inorganic agent, a hydrocarbon, a halogenated hydrocarbon, a hydrocarbon with polar, functional group(s), water or any combination thereof), or a chemical co-blowing agent, or combinations thereof. The thermoplastic polymer foam can be an alkenyl aromatic polymer foam, e.g. a polystyrene foam. The blowing agent blend includes methyl formate and one or more co-blowing agents. The methyl formate-based blowing agent blends produce dimensionally stable foams that have improved resistance to flame spread. A process for the preparation of such foams is also provided.

    Abstract: Fluoropolymer foams are prepared by mixing fluoropolymer resin with blowing agents and additives to produce foamable compounds at temperatures below the activation temperature of the blowing agent. The compounded material is expanded at temperatures above both the softening point of the fluoropolymer resin and the activation temperature of the blowing agent. The resulting fluoropolymer foam can be fabricated into any desired shape, such as pipes, sheets, tapes, blocks and rods, using techniques such as cutting, welding, thermoforming and adhesive bonding. Alternatively the fluoropolymer compound may be expanded directly into the desired shape, for example, by expanding the compound in a mold.
