Thermoplastic polyurethane solutions for low smoke zero halogen (LSZH) flame retardant cable applications

摘要

New grades of halogen free flame retardant thermoplasticrnpolyurethane for cable jacketing combine high flame retardance,rnlow smoke density and low smoke toxicity with high levels ofrnmechanical properties. They show a high limiting oxygen index,rnlow maximum of heat release rate in cone calorimetry, improvedrnindex of toxicity and rating for rolling stock.
