NORYL™ WCA955 resin

About
Non-halogenated flame retardant Flexible NORYL extrusion grade intended for evaluation in wire insulation, especially for internal wire. Excellent flame retardant performance with balanced tensile strength, tensile elongation, heat deformation, capable of VW-1 performance and 105C temperature rating as defined by UL 1581. Processing typically conducted on standard extrusion equipment. UL 1581 tests conducted on 2.0mm wire with 0.12mm X 20 stranded copper conductor. It”s also suitable for coating of AWG26 and AWG28 copper conductor as well.&&
