| Casico FR4804 is a thermoplastic, low smoke zero halogen (LSZH) flame retardant, UV stabilised, natural jacketing 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 Casico FR4804 is designed for: Jacket for data cables and 90 °C rated jacket for energy distribution cables. It can be used in areas sensitive to smoke or corrosive and toxic combustion products. Specifications Casico FR4804 meets the applicable requirements below using sound commercial extrusion practice and testing procedures: ASTM D 1248 Type I, Class A, Category 4 ISO 1872-PE KGHN-23D006 The following cable material standards are met by Casico FR4804: EN 50290-2-27 EN 50363-8 TM7 VDE 0207 Teil 24 (HM2, HM4 & HM5) BS 7655 LTS2 Cables manufactured with Casico FR4804 using sound extrusion practice normally comply with the following cable product standards: EN 50288 VDE 0250 Teil 215 BS 7211 IEC 60502 Part 1 ST3 Special features Casico FR4804 consists of specially selected components to offer: Low smoke and reduced toxic or corrosive gas emissions Excellent processing properties Superb system ageing compatibility Low water permeability UV stabilised and suitable for colouring Possibility for cable downsizing Processability on most PVC/PE extrusion equipment No need for pre-drying normally&& |
