Abstract
The present invention concerns the use of carbon black for reducing the shrinkage of a polyolefin composition to below 0.9%, wherein the polyolefin composition comprises a polyolefin polymer, and carbon black in an amount of from 0.05 to 2 wt. % based on the total weight of the polyolefin composition.
Claims15
