Abstract
Provided is an ECTFE resin composition that is superior in transparency and resistant to yellowing for an extended period of time. The ECTFE resin composition generates a smaller amount of acidic gases, for example, when it is extrusion molded at high temperature. It is an ethylene-chlorotrifluoroethylene copolymer resin composition including a bisphenol-based antioxidant. It is preferably an ethylene-chlorotrifluoroethylene copolymer resin composition additionally including a phosphorus-based antioxidant.
