Title
(EN) APPARATUS AND METHOD FOR THE REDUCTION OF POLYOLEFIN INSULATION CRACKING OF CABLES
(FR) PROCEDE ET APPAREIL DE REDUCTION DE LA FISSURATION D'ISOLATIONS EN POLYOLEFINE DE CABLES
Abstract
(EN)
The invention provides for a method and various apparatus and article embodiments for inhibiting polyolefin degradation or cracking of fine wires, e.g., the wires used in telecommunications. More specifically, the invention provides for a method of inhibiting polyethylene insulation cracking and apparatus and compositions for controlling the degradative effect of acid and/or volatile vapors on the polyethylene insulation.
(FR)
Un procédé, plusieurs appareils et articles permettent d'inhiber la dégradation des polyoléfines ou la fissuration de minces fils métalliques, par exemple les fils utilisés en télécommunications. En particulier, l'invention concerne un procédé d'inhibition de la fissuration d'isolations en polyéthylène et des appareils et compositions de réduction de l'effet dégradant d'acides et/ou de vapeurs volatiles sur des isolations en polyéthylène.
