Borealis Visico™ ME4425/LE4462 Scorch Retardant Silane Crosslinkable MDPE Track Resistant Cable Insulation
Categories: Polymer; Thermoplastic; Polyethylene (PE); Medium Density (MDPE); Medium Density Polyethylene (MDPE), Extruded

Material Notes: Visico ME4425/LE4462 is a combination of LE4425, a Medium Density Visico base resin and a masterbatch, LE4462, which contains catalyst, carbon black, UV stabilizers and antioxidants. The LE4462 masterbatch accelerates the moisture-induced crosslinking reaction and imparts track resistance, resistance to degradation by ultraviolet light stability to the final product.

Visico ME4425/LE4462 is designed for use as a track resistant insulation for the outer layer of Spacer Aerial Cables and as insulation for Partial Insulated Cables. Although it has been used alone as insulation for cables rated at voltages as high as 35kV, it is recommended that a conductor shield such as LE540 be used for cables rated at voltages above 12 kV or where required by the applicable electrical code.
