The present invention overcomes the disadvantages of polyphenylene ether resin compositions, has excellent high-temperature creep characteristics, has rigidity in a high-temperature range (60 to 95 ° C.), can use the same production equipment as vinyl chloride resin, and has moldability. Providing piping members with good appearance. SOLUTION: From 100 parts by mass of a polyphenylene ether resin, a resin composition having 50 to 12 parts by mass of a polystyrene resin as an essential component and having a melt flow rate after kneading of 1.0 to 5.0 g / 10 min. A piping member. In addition, the mold shrinkage is 0.5 to 0.8%, and the high temperature creep characteristics with a tensile load of 5.0 MPa in a 95 ° C. atmosphere require 1000 hours or more to break. The water content before molding of the resin composition after kneading is less than 250 ppm, which is an individual feature. [Selection figure] None |
