| Casico™ FR4803是一种热塑性、低烟无卤（LSZH）阻燃、紫外线稳定的天然护套化合物，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。它可用于对烟雾或腐蚀性和有毒燃烧产物敏感的区域。对于大多数电缆结构，Casico™ FR4803具有足够的阻燃性，以满足单线垂直燃烧试验。Casico™ FR4803符合以下使用良好的商业挤压实践和测试程序的适用要求：BS 7655 LTS1-4 EN 50173 EN 50288 EN 50290-2-27 EN 50363-8 TM7 IEC 60227 VDE 0207 TEIL 24（hm2、hm4和hm5）VDE 0250 TEIL 215 Casico FR4803 is a thermoplastic, low smoke zero halogen (LSZH) flame retardant, UV stabilised, natural jacketing compound combining with excellent extrusion properties. The composition is based on the elements Carbon, Hydrogen, Oxygen, Silicon and Calcium. Compounds based on these elements will therefore be the only significant constituents of the combustion fumes. Other elements may be present in concentrations less than 0.1%. 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 FR4803 is designed for: Jacket for 90 °C rated building wires (installation cables) and 1 kV low voltage cables It can be used in areas sensitive to smoke or corrosive and toxic combustion products. For most cable constructions, Casico FR4803 has sufficient flame retardancy to satisfy single wire vertical burning tests. Specifications Casico FR4803 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 FR4803: EN 50290-2-27 EN 50363-8 TM7 VDE 0207 Teil 24 (HM2, HM4 & HM5) BS 7655 LTS1-4 Cables manufactured with Casico FR4803 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 FR4803 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 |
