Visico™ LE4421M / Visico™ LE4431M

Technical Datasheet | Supplied by Borealis

Visico™ LE4421M / Visico™ LE4431M by Borealis is a silane crosslinkable, polyethylene (XLPE) grade. Visico™ LE4421M (base material) in combination with Visico™ LE4431M (catalyst masterbatch) accelerates moisture induced crosslinking reaction. Exhibits low odour during processing, very good surface finish, long shelf life, longer production runs between cleaning stops and quick change-over for short length cables. Designed for processing by extrusion. Visico™ LE4421M / Visico™ LE4431M is recommended for insulation of XLPE medium voltage cables with rated voltages up to 36 kV.
