摘要

The composition of thermoplastic polyurethane flame retardant halogen-free flame retardant, the packaging of non halogenated, processes for production of a composition of thermoplastic polyurethane flame retardant halogen-free and for the production of a construction of cable and wire, cons Establishment of cable and wire, and article content.Disclosed are compositions of thermoplastic polyurethane (TPU) flame retardant and a pack of flame retardant containing an organo fosfinato component, a component of organic phosphate, and an alcohol poliu00eddrico.The components flame retardants may be present in an amount of about 5 to about 40% by weight of the compound of fosfinato; about 5 to about 20% by weight of phosphate compound, and about 0.1 to about 15% by weight of alcohol poliu00eddrico, based on the total weight the form Tion of TPU.Are disclosed processes parapreparau00e7u00e3o of compositions of TPU and the manufacture of wires and cables coated with the compositions of TPU and cover the same. The TPU compositions have excellent capabilities to flame retard measures by limit oxygen index test and / or vertical burning tests UL / 94.
