MASTER BATCH

摘要

A master batch for the production of cross-linked polymer pipes is described. The master batch comprises carbon black and a polymer carrier consisting of a Ziegler-Natta catalysed polyethylene with a density of at least 0.940 g/cm<3>. A cross-linkable polymer composition comprising the master batch and a chromium catalysed polyethylene base polymer, and a cross-linked polyethylene pipe made by cross-linking the cross-linkable polymer composition are also described.
