Ces films sont non renforc\u00e9s et semi-cristallins en polym\u00e8re PEEK\u2122-Polyetheretherketone. Ils offrent aux ing\u00e9nieurs une solution mat\u00e9rielle pour les applications \u00e0 hautes performances. Ils pr\u00e9sentent une combinaison unique de propri\u00e9t\u00e9s telles que la r\u00e9sistance aux temp\u00e9ratures \u00e9lev\u00e9es, la l\u00e9g\u00e8ret\u00e9, la r\u00e9sistance m\u00e9canique, la durabilit\u00e9, une excellente r\u00e9sistance aux radiations, \u00e0 l’hydrolyse et aux produits chimiques, l’isolation \u00e9lectrique, la r\u00e9sistance \u00e0 l’abrasion et \u00e0 l’usure, d’excellentes propri\u00e9t\u00e9s de barri\u00e8re avec une grande puret\u00e9, un faible niveau d’inflammabilit\u00e9 sans utilisation de retardateurs de flamme, une faible toxicit\u00e9 des produits de combustion et une faible absorption d’humidit\u00e9. Les films intrins\u00e8quement ignifuges sont faciles \u00e0 mettre en \u0153uvre.<\/h5>\n
