Abstract: A foamed material includes 50 to 90 weight percent of a semicrystalline resin and 10 to 50 weight percent of a poly(phenylene ether). The semicrystalline resin can be one or more of a polyamide, a polyester, and a polyolefin. The foamed material has a density of 40 to 700 kilograms/meter3. It can be prepared by adding a blowing agent to a molten thermoplastic material containing the semicrystalline resin and the poly(phenylene ether), thereby forming a pre-foamed molten thermoplastic material, and extruding the pre-foamed molten thermoplastic material to form the foamed material. The foamed material is useful to form articles requiring solvent resistance.
