Publication number: 20110168425Abstract: Commercial thermoplastic clean flame retardant materials in wire and cable insulation are mechanically unstable due to high filler loading. In the present invention, thermoplastic, black color, clean flame retardant composition using carbon nano tubes (CNT) is made. The resultant compositions possess very low smoke and toxicity. CNT with outer diameter of 40-60 nm and length of under 20 ?m are used to increase mechanical properties and flame retardancy. Thermo plastically extruded composition consists of each component by parts by weight as follows: 100 of resin (polyolefin or 100 of polyolefin/ethylene propylene diene monomer (EPDM)), 90-150 of non halogen containing flame retardants, 1-20 of auxiliary secondary flame retardant agents, 2-4 of CNT (outer diameter of 40-60 nm) and length under 20 ?m and 0.2-1.0 of antioxidants. A reliable method for producing thermoplastic black color clean flame retardant insulation material for wire and cable without deterioration of mechanical properties is discussed.Type: ApplicationFiled: January 8, 2010Publication date: July 14, 2011Inventors: Ahmed Ali Basfar, Hun Jai Bae
