Title
(EN) PLASTICS PIPE
(FR) TUYAU DE PLASTIQUE
Abstract
(EN)
Use, in a plastics pipe which comprises an inner core and an outer removable skin layer bonded thereto, wherein the outer removable skin layer comprises a polymeric material chosen for its physical and mechanical properties, of a nucleating agent for the polymeric material, the nucleating agent being present in the skin layer in an amount such that the adhesion of the skin layer to the inner core is sufficient to prevent substantial undesired relative movement between the skin layer and the core during installation, but insufficient to prevent the outer skin layer from being cleanly removed by peeling, at least at the ends of the pipe, and insufficient to cause a substantial reduction in the impact strength of the inner core.
(FR)
L’invention concerne l'utilisation, dans un tuyau de plastique comprenant un noyau interne et une couche de protection amovible externe collée sur celui-ci, la couche de protection amovible externe comprenant un matériau polymérique retenu pour ses propriétés physiques et mécaniques, d’un agent de nucléation pour le matériau polymérique, l’agent de nucléation étant présent dans la couche de protection dans une quantité telle que l’adhérence de la couche de protection au noyau interne soit suffisante pour empêcher tout mouvement relatif indésirable sensible entre la couche de protection et le noyau pendant l’installation, mais insuffisante pour empêcher la séparation propre de la couche de protection externe par détachage, au moins aux extrémités du tuyau, et insuffisante pour provoquer une réduction sensible de la résistance aux impacts du noyau interne.
