The flame retardant grade of TPU is the same as that of general wire products, and a little better V1, ordinary V2                                     Halogen-free flame retardant TPU polyurethane raw materials, polyester / polyether, hardness: 71A - 95A, the processing level can be divided into: injection molding / extrusion processing, color: Black / White / Grey / transparent, bright surface / surface effect to semi matte / fog surface quality: no powder, no precipitation, cold. Hydrolysis resistance, oil resistance, abrasion resistance, weather resistance, flame retardant grade: UL94-V0/V2, making wire by: VW-1 (vertical burning test does not drip).         Thermoplastic polyurethane elastomer (TPU) has excellent mechanical properties, wear resistance, solvent resistance, high temperature resistance and other comprehensive properties. It is an ideal coating material for wire and cable. However, TPU itself is easy to burn, and it is accompanied by droplets, which can easily ignite the surrounding flammable substances and aggravate the occurrence of fire. Therefore, thermoplastic polyurethane elastomer (TPU) should be widely used in the field of wire and cable, so it is necessary to further improve its flame retardancy.             Hello,i am Cherry,if you need any help,pls contact me via email:injectionmold2008@163.com  Whatsapp:+86 15112289056
