Material Notes:
Casico™ FR4820 is a thermoplastic, low smoke zero halogen (LSZH) flame retardant, UV stabilized, natural insulation compound combining with excellent extrusion properties. It is based on the novel technology, Casico™, containing inorganic filler and a novel char-forming additive which confer flame retardancy with very limited smoke generation. Applications: 70°C rated insulation for building wires (installation cables), flexible cords, and power cables. It can be used in areas sensitive to smoke or corrosive and toxic combustion products. Casico™ FR4820 is stabilized for use in contact with copper. Specifications: Casico™ FR4820 in combination meets the applicable requirements as below when processed using extrusion practice and testing procedure: EN 50292-2-26; EN 50363-7 TI6; and EN 50363-7 TI7.Information provided by Borealis AG
