        TPU Halogen Free Flame Retardant - EPFR-400A



        Preniphor?EPFR-400A, mainly contains N and P, is a kind of halogen free environmentally friendly flame retardant. It has been developed especially for the thermoplastic polyurethane and thermoplastic elastomer (TPE). This flame retardant functions in the condensed phase and the gas phase. The FR TPU can be used in power cables, communication cables, geographic exploration cables and auto cables, etc. 


        TPU with EPFR-400A can pass the tests of UL 94 V-0 (0.75mm), UL 1581 VW-1 and other flame retardant grades. TPE with EPFR-400B can pass the tests of UL 1581 VW-1. Moreover, it is free from the restrictions of RoHS Directive 2002/95/EC approved by the EU and the Council. The products with EPFR-400A are characterized by smooth appearance, strong precipitation resistance, excellent water and migration resistance, good electrical properties, no toxicity and low smoke generation. 


        EPFR-400A is more suitable for the injection products and wires with normal surface requirements. NO anti-dripping agent. About 2‰ of anti-dripping agent (such as TF 1645 from 3M corporation) can be added in accordance with the actual demand of the customers.
