Abstract
Provided are a resin composition and shaped product having excellent low-temperature impact resistance, chemical resistance, and tracking resistance, and having rigidity enabling adoption for mechanism components and structures. The resin composition contains (a) a polyphenylene ether resin, and further contains: (b-1) a hydrogenated block copolymer, and/or modified product thereof, having a peak molecular weight of 80,000 to 200,000 and (b-2) a hydrogenated block copolymer, and/or modified product thereof, having a peak molecular weight of at least 10,000 and less than 80,000; and/or (c) an olefinic polymer formed from an olefin other than propylene. The (a) component forms a continuous phase, polymer block B has a glass transition temperature of −50° C. or lower, the (c) component has a brittleness temperature of −50° C. or lower, and the composition does not substantially contain (g) polypropylene resin and has a flexural modulus of 1,600 MPa or more as measured in accordance with ISO 178.
