Abstract

La présente invention se rapporte à une enveloppe protectrice de câble exempt de poussière et son procédé de fabrication, l'enveloppe protectrice de câble exempt de poussière comprenant : deux premiers matériaux dans lesquels un premier film de polytétrafluoroéthylène expansé (ePTFE) est formé sur une surface d'un premier film de polyuréthane thermoplastique (TPUR) ; un deuxième matériau dans lequel un second film d'ePTFE est formé sur une surface d'un deuxième film de TPUR ; et un troisième matériau dans lequel un film de polyéthylène de poids moléculaire ultra-élevé (UHMWPE) est formé sur une surface d'un troisième film de TPUR, plusieurs paires de premiers matériaux étant agencées espacées les unes des autres entre le deuxième matériau et le troisième matériau, des parties stratifiées étant formées par liaison thermique des deux premiers matériaux, du deuxième matériau et du troisième matériau, et une partie d'insertion de câble étant formée entre les parties stratifiées. L'enveloppe protectrice de câble exempt de poussière et son procédé de fabrication selon la présente invention réduisent à un minimum la production de poussière sur la surface externe et permettent d'obtenir une durabilité élevée et une excellente aptitude au traitement par liaison thermique du film de TPUR, du film d'ePTFE et du film de polyéthylène de poids moléculaire ultra-élevé dans des conditions optimales.
