Abstract:
1. Polyolefin composition comprising a crosslinkable polyolefin with hydrolysable silane groups and a silanol condensation catalyst, characterized in that said silanol condensation catalyst is an organic sulphonic acid comprising 10 C-atoms or more and that said polyolefin composition further comprises (A) from 0.04 to 0.4 wt % of a compound selected from the group consisting of bis(2,4-dicumylphenyl)pentaerythritoldiphosphite and di-stearyl-pentaerythrityl-di-phosphite; and (B) from 0.08 to 1.5 wt % of a non-phosphorous containing antioxidant selected from the group consisting of 1,3,5-tri-methyl-2,4,6-tris-(3,5-di-tert.butyl-4-hydroxyphenyl)benzene, 2,5,7,8-tetramethyl-2(4′,8′,12′-trimethyltridecyl)-chroman-6-ol, a butylated reaction product of p-cresol and dicyclopentadiene, and tetrakis-(methylene-(3,5-di-tert.butyl-4-hydrocinnamate))-methane.
