UV stabilized silane crosslinkable polyethylene compound for aerial cables This is a silane crosslinkable polyethylene compound, curable by exposure to moist conditions, and possessing excellent extrusion properties at high output rates. The graft component SX490 is mixed with a crosslinking catalyst masterbatch CM401 or CM401-2 generally in the ratio 95:5. The compound contains 2.5% carbon and has been specially developed for insulated "overhead" or aerial cables of the bunched type, and enables full compliance with the German specification VDE 0274. It is advisable to use CM401-2 for less than 1mm thin wall applications; this is normally added at 10% to 90% graft. |
