A silane grafted Crosslinkable polyethylene compound, curable by exposure to moisture, for insulation of power cables and possessing excellent extrudability at high output rate.

PP 409 has been specially developed for cables up to 72 KV. The special formulation and compounding techniques used ensures that the contamination level is kept within the required limits for this voltage grade.

PP 409 has general melt index range of 0.7 - 1.0 which provides firm stability during extrusion, especially for the thick insulations required for high voltage.

DESCRIPTION :
This compound utilizes the system for crosslinking of polyethylenes developed by DOW coming and known as sioplas. It is a two-component system comprising a silylated ethylene polymer known as the graft copolymer PP 409, and a masterbatch PP401 containing a crosslinking catalyst. The two materials normally used in the ratio of 95 parts graft to 5 parts catalyst masterbatch.
