Some wire and cable makers replace PVC with material like PE, LDPE to avoid toxicity issues and support sustainability, but they face some challenges, such as HFFR PE cable compounds having high filler loading of metal hydrates, These fillers and additives negatively affect processability, including reducing screw torque that slows down throughput and using more energy and increasing die build-up which requires frequent interruptions for cleaning. To overcome these issues and optimize throughput, wire and cable insulation extruders incorporate silicone masterbatch as processing additives to optimize productivity and enhance dispersion of flame retardants such as MDH/ATH.

However, SILIKE offer all kinds of ultra high molecular weight silicone additives, Silicone Masterbatch LYSI-401, it is designed to be used as processing aids and surface modifiers in PE compatible system to reduce melt viscosity, improve processability and compounding productivity, by enhancing the flame retardants dispersion, helps in reducing the COF, gives smooth surface finish properties, which improves the scratch resistance. as well as, benefit in saving energy costs by the lower extruder and die pressure, and avoiding die throughput for PE compounds in several build-ups on the extruder.
