Title (EN) STABILIZING ETHYLENE-TETRAFLUOROETHYLENE COPOLYMERS
(FR) STABILISATION DE COPOLYMERES D'ETHYLENE-TETRAFLUOROETHYLENE
Abstract:
(EN) The stability of a composition comprising an ethylene-tetrafluoroethylene copolymer; in particular, its stability when subjected to elevated temperature for a significant period of time is improved by incorporating therein a sulfide of a Group IIb metal. The composition may be crosslinked. Heat recoverable articles made of the composition are useful as wire and cable harnessing, boots, and sleeves.
(FR) On améliore la stabilité d'une composition comprenant un copolymère d'éthylène-tétrafluoroéthylène, notamment sa stabilité lorsqu'il est soumis à une température élevée pendant une durée significative, en lui incorporant un sulfure d'un métal du groupe IIb. On peut réticuler la composition. Des articles thermorécupérables réalisés à partir de la composition sont utiles comme harnais de fils et de câbles, bottes et manchons.
