Title (EN) POLYMERIC COMPOSITIONS FOR OPTICAL FIBER CABLE COMPONENTS
(FR) COMPOSITIONS POLYMÉRIQUES POUR COMPOSANTS DE CÂBLE À FIBRE OPTIQUE
Abstract:
(EN) Polymeric compositions comprising a polybutylene terephthalate; a low-density polyolefin selected from a low-density polyethylene, a polyolefin elastomer, or combinations thereof; and a maleated ethylene-based polymer. Optical cable components fabricated from the polymeric composition. Optionally, the polymeric composition can further comprise one or more additives, such as a filler. The optical fiber cable components can be selected from buffer tubes, core tubes, and slotted core tubes, among others.
(FR) L'invention concerne des compositions polymériques comprenant un polybutylène téréphtalate ; une polyoléfine basse densité choisie parmi un polyéthylène basse densité, un élastomère polyoléfinique, ou des combinaisons de ceux-ci ; et un polymère à base d'éthylène maléaté. L'invention concerne des composants de câble optique fabriqués à partir de la composition polymérique. Éventuellement, la composition polymérique peut en outre comprendre un ou plusieurs additifs, tels qu'une charge. Les composants de câble à fibre optique peuvent être choisis, entre autres, parmi des tubes tampons, des tubes de noyau et des tubes de noyau rainurés.
