Abstract: 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 (B) 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, triazines, benzophenones, triazoles and/or combinations thereof; and at least one UV stabilizer of the hindered amine type (HALS) which is present in an amount of 0.0001 to 0.1 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.
