Abstract
The present invention is directed to particular titanium dioxide containing compositions which allow the retention of a high crosslinking performance of a polyolefin composition comprising a crosslinkable polyolefin with hydrolysable silane groups, a Brönstedt acid silanol condensation catalyst and said titanium dioxide containing composition. The retention of the high crosslinking performance is shown by a difference in torque measured at 120° C. of 40 Nm or higher.
