|---|
| A silane grafted crosslinkable polyethylene compound, curable by exposure to moisture, for insulation of power cables and possessing excellent extrudability at high out put rate. PP 408 is based on a high molecular weight polymer and has melt index in the range of 0.5 to 0.8. It has especially developed for low voltage cable insulation and for sheathing purpose. DESCRIPTION : This compound utilizes the system for cross – linking of polyethylene developed by DOW Corning and known as Sioplas. It is a two component system comprising a silylated ethylene polymer known as the graft copolymer PP 408 , and a master batch PP 401 containing a cross – linking catalyst. The two materials normally used in the ratio of 95 parts graft to 5 parts catalyst master batch.&& |
