FR4810 is a thermoplastic, low smoke zero halogen (LSZH) flame retardant, black jacketing compound combining with flexibility and exceptional fluid resistance. The composition is based on the elements Carbon, Hydrogen, Oxygen, Silicon and Magnesium. 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%. Its excellent flame retardancy is achieved by an inorganic filler and a novel char-forming additive. Applications FR4810 is designed for: -90°C rated jacket for energy cables with high flame retardancy required The high operating temperatures and durability (abrasion resistance, hardness) of FR4810 makes it an attractive solution for energy cables installed in industrial areas, tunnels, ducts The ability of this compound to be used for both internal and external applications is valuable as it avoids the requirement of cable splicing at building service entrances. It can be used in areas sensitive to smoke or corrosive and toxic combustion products. In general, FR4810 has sufficient flame retardancy to satisfy bunched cable vertical burning tests. Specifications FR4810 meets the applicable requirements below using sound commercial extrusion practice and testing procedures: - ISO 1872-PE, KCGH, 33-D001 - ASTM D 1248 Type I, Class C, Category 4 The following cable material standards are met by FR4810: - EN 50290-2-27 - EN 50363-8 TM7 - VDE 0207 Teil 24 (HM4) - BS 7655 LTS2 Cables manufactured with FR4810 using sound extrusion practice normally comply with the following cable product standards: - IEC 60502, Part 1, Type ST3, ST8 Special Features FR4810 consists of specially selected components to offer: - Low smoke and reduced toxic or corrosive gas emissions - Excellent processing properties - High mechanical strength and toughness - Superb system ageing compatibility - Low water permeability - UV resistance - Processability on most PVC/PE extrusion equipment - No need for pre-drying normally

PP4821 is a thermoplastic, non-halogen containing, insulation compound based on a polypropylene copolymer. The composition of PP4821 is based on the elements Carbon and Hydrogen. Compounds based on these elements will therefore be the only significant constituents of the fumes due to the combustion of this product. Other elements may be present in concentrations less than 0.1% Applications PP4821 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. PP4821 is stabilised for use in contact with copper.
