  • FLUORORESIN, MULTILAYER PRODUCT, AND TUBE
    Publication number: 20230203296
    Abstract: A fluororesin having a tensile strength retention ratio of 50% or more, the tensile strength retention ratio being calculated by the following formula from the tensile strength of the fluororesin after a heat treatment obtained by conducting a heat treatment at 130° C. for 40,000 hours, and the tensile strength of the fluororesin before the heat treatment. Tensile strength retention ratio (%)=(tensile strength of fluororesin after heat treatment (MPa))/(tensile strength of fluororesin before heat treatment (MPa))×100.

  • FLUORINE RESIN MATERIAL, LAMINATE, TUBE, AND TUBE MANUFACTURING METHOD
    Publication number: 20230183466
    Abstract: A fluororesin material containing a fluororesin. The fluororesin has a carbonyl group, the total number of carbonyl groups is 1 or more and less than 800 per 106 main-chain carbon atoms, and the fluororesin contains ethylene unit and tetrafluoroethylene unit. When the fluororesin material is heated at a rate of 10° C./minute, the initial pyrolysis temperature when the mass reduction of the fluororesin material reaches 1% by mass is 390° C. or more.
