Most applications of TPU in this industry have higher requirements for flame retardancy, and with the development of TPU application, the flame retardancy of TPU will be normalized. 

At present, most of the flame retardant TPU used in wire and cable industry is halogen-free (halogen-free flame retardant is widely used in industry due to the toxicity of Halogen) . And with the application of TPU cable industry expansion, can be expected, halogen-free flame retardant TPU materials will further increase the demand!


A wide variety of elastomers are available for cable coverings and insulation Thermoplastic Elastomer.

 The main products used for cable coverings and insulation are Polyolefin Thermoplastic Elastomer, styrene Thermoplastic Elastomer, thermoplastic polyurethane elastomers (TPU) , polyester Thermoplastic elastomer etc. . 

Among them, as a result of TPO and SBC class very good insulation resistance, so used for cable and insulation layer is more; and TPU, TPUE is generally used for cable.

Halogen-free flame-retardant elastomer is a kind of composite material which is based on resin and rubber and contains a lot of organic compounds. Flame retardants exert their flame retardancy through several mechanisms, such as endothermic effect, covering effect, inhibition of chain reactions, asphyxiation effect of non-combustible gases, etc. . 

Most flame retardants work together through several mechanisms to achieve flame retardancy.
