Borealis Visico™ FR4451/LE4439 Polyethylene, Silane Crosslinkable Insulation Compound
Categories:	Polymer; Thermoplastic; Polyethylene (PE)
Material Notes:	Visico FR4451/LE4439 is a natural UV stabilized, halogen free moisture-induced crosslinkable polyethylene compound that is designed for use in photovoltaic cables. The combination of Visico FR4451 base resin, and LE4439 catalyst, provides a highly scorch retardant compound system with excellent thermal stability and good flame retardant properties. Visico FR4451/LE4439 contains a patented scorch retardant additive that increases the processing window for a silane crosslinkable compound and minimizes the tendency for premature crosslinking in the extruder, head or die. Cable insulation with a proper mixture of Visico FR4451 (95 parts) and LE4439 (5 parts) exhibits excellent thermo-oxidative stability in contact with aluminum or copper. Visico FR4451/LE4439 can be readily pigmented to a variety of colors using standard wire & cable color concentrates designed for thermoplastic or crosslinked polyethylene. Applications: Visico FR4451/LE4439 is recommended for use as insulation and jacket of flexible single-core cables (cords) at the DC-side of photovoltaic systems with maximum permissible voltage of DC 1.5 kV. Specifications: Visico FR4451/LE4439 in combination meets the applicable requirements as below when processed using sound extrusion and testing procedure: TÜV 2 PfG 1169/08.2007; EN 50618; EN 50363-5 EI5; EN 50290-2-26 Information provided by Borealis AG
