た。これを環境応力割れ性と称する。Conventionally, tetrafluoroethylene-hexafluoropropylene resin compositions have excellent physical, chemical, mechanical, thermal, and electrical properties, and are easy to process by extrusion, injection, and molding methods. Although it is being widely used as a molding material for industrial and consumer institutions, recently developed environmental substances such as
It has been found that when immersed in or in contact with animals, plants, mineral oils and fats, plasticizers, organic solvents, etc. under stress, cracks are generated, which then grow and lead to destruction. This is called environmental stress cracking.

果が認め難いためである。The present invention is a novel tetrafluoroethylene-hexafluoropropylene resin composition that improves environmental stress cracking properties without impairing the excellent physical, chemical, mechanical, thermal, and electrical properties inherent in the tetrafluoroethylene-hexafluoropropylene resin composition. An object of the present invention is to provide a composition based on an ethylene tetrafluoride-propylene hexafluoride copolymer resin composition. 100 parts by weight, both tetrafluoroethylene and perchloroalkoxyethylene have a remarkable effect on improving the environmental stress cracking resistance, and the reason for this is currently under investigation. The amount added is limited from the viewpoint of the effect on the environmental stress resistance of the composition, and the effect is difficult to notice if it is less than 0.5 parts by weight.
