Patent ID: 7445839

Claim:
A foam sheet for a car interior member, said foam sheet comprising a modified polyphenylene ether-based resin foam sheet having an open cell ratio of 60 to 85% as a whole, and modified polyphenylene ether-based resin sheets integrally laminated on both faces of the modified polyphenylene ether-based resin foam sheet, wherein the modified polyphenylene ether-based resin foam sheet comprises (1) a foamed layer and (2) pore portions formed in a single face of said foam sheet so as to be open in said face, wherein the foam layer comprises an open cell layer having an open cell ratio of 70% or more, wherein the ratio of the total opening area of the pore portions to the surface of the foam sheet is from 2 to 50%, wherein the opening end area of the pore portions is from 0.2 to 40 mm 2 , wherein the pore portions are (A) specifically shaped and have a depth to induce the vibration energy of sounds into the open cells of the open cell layer of the foam sheet, and (B) opened to the surfaces of the modified polyphenylene ether-based resin sheets, wherein said modified polyphenylene ether-based resin sheets contain no foam cells, and wherein the modified polyphenylene ether-based resin constituting the modified polyphenylene ether-based resin sheet has a glass transition temperature T g 10 to 40° C. lower than a glass transition temperature T g of the modified polyphenylene ether-based resin constituting the modified polyphenylene ether-based resin foam sheet.
