Casico™ FR4820是一种热塑性、低烟无卤(LSZH)阻燃、紫外线稳定的天然绝缘化合物,具有优异的挤出性能。它是基于一种新型的技术,即含有无机填料的CASICO和一种新型的成炭添加剂,这种添加剂具有阻燃性,且烟雾生成非常有限。当使用挤压实践和试验程序进行加工时,Casico™ FR4820组合符合以下适用要求:EN 50292-2-26 EN 50363-7 TI6 EN 50363-7 TI7 Casico FR4820 is a thermoplastic, low smoke zero halogen (LSZH) flame retardant, UV stabilised, 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 Casico FR4820 is designed for: 70°C rated insulation for building wires (installation cables), flexible cords, power cables It can be used in areas sensitive to smoke or corrosive and toxic combustion products. Casico FR4820 is stabilised for use in contact with copper. Specifications Casico FR4820 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 FR4820: EN 50290-2-26 EN 50363-7 TI6 & TI7 VDE 0207 Teil 23 (HM2) Special features Casico FR4820 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 Processability on most PVC/PE extrusion equipment No need for pre-drying normally |
