longer shelf life than most currently available solutions. According to Bart Verheule, head of Marketing,


Visico FR4450 is an LFH solution for building and


industrial wire, and unlike conventional applications based on brominated fl ame-retardant additives, is halogen-free. Visico FR4451 is designed to meet demanding requirements for photovoltaic cables. When used in combination with LE4439 in insulation and jacketing, it is claimed to enable easier processing and a


Energy at Borealis, there is a growing demand for cross-linkable fl ame retardant wire and cable com- pounds for US building wire and solar cable applica- tions. “Visico FR is a new family of compounds based on a combination of Visico cross-linking technology and the Casico fl ame retardant technology platform,” he says. “Visico FR4450 is designed to pass Underwriters Laboratories UL 44 and UL 854 building wire standards and Visico FR 4451 passes solar cable standards TÜV 2PfG1169 and EN50618. These compounds offer good extrusion performance, smooth cable fi nish, superior wet electrical properties and increased fl exibility versus alternative materials. Visico FR therefore offers a cost competitive and a more environmentally sustainable solution against halogenated systems, which are still commonly used in the US.” The introduction of the new Visico FR compounds


follows on from the introduction in 2014 of the polyolefi n maker’s Borlink LS4258DCE extruded cable technology for signifi cantly higher voltage and transmission levels, as well as its Borlink LS4201EHV for demanding EHV
