Title
(EN) UV STABILIZATION OF A CROSS-LINKABLE POLYOLEFIN COMPOSITION COMPRISING AN ACIDIC SILANOL CONDENSATION CATALYST
(FR) STABILISATION AUX UV D'UNE COMPOSITION DE POLYOLÉFINE RÉTICULABLE COMPRENANT UN CATALYSEUR DE CONDENSATION AU SILANOL ACIDE
Abstract
(EN)
The present invention relates to a polyolefin composition comprising a cross-linkable polyolefin with hydrolysable silane groups, an acidic silanol condensation catalyst, wherein the acidic silanol condensation catalyst is present in an amount of 0.0001 to 3 wt.% of the polyolefin composition, at least one UV stabilizer selected from the group consisting of phenols, benzophenones and/or combinations thereof, wherein component (C) is present in an amount of 0.0001 to 0.35 wt.% of the polyolefin composition, and/or at least one UV stabilizer selected from triazines, wherein component (D) is present in an amount of 0.0001 to 2.0 wt.% of the polyolefin composition. The present invention also relates to an article comprising such a composition, and to the use of such a composition for the production of an article.
