<p><P>PROBLEM TO BE SOLVED: To provide a piping member overcoming defects of polyphenylene ether-based resin compositions, excellent in high temperature creep property, having rigidity even at a high temperature (60-95°C), capable of being produced by using the same production system as that for vinyl chloride resins and having good moldability and good appearance. <P>SOLUTION: The piping member comprises a resin composition comprising 100 pts.mass polyphenylene ether-based resin and 50-12 pts.mass polystyrene-based resin as essential components and having 1.0-5.0 g/10 min melt flow rate after kneading. The elements are further characterized in each of a mold shrinkage of 0.5-0.8%, a high temperature creep property of≥1,000 h till breakdown under conditions of 95°C atmosphere and 5.0 MPa tension load, and a moisture content in the resin composition, of <250 ppm after kneading and before molding. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
