TPU cable sheath material is made of polyether polyurethane resin as the base material, and is mixed with halogen-free environmentally friendly flame retardants, additives, etc. and extruded into granules. It combines high performance, high and low temperature resistance, flame retardancy, wear resistance, oil resistance and other excellent properties, and has no precipitation.
Halogen-free flame retardant TPU is a halogen-free environmentally friendly material with phosphorus and nitrogen as flame retardant elements. The mechanical properties meet the requirements for the use of TPU wires in the UL1581 standard, and the flame retardancy reaches UL1581VW-1, UL94V-0, V-1, V-2 and CSAFT-2, FT-1 levels.
This product is soft, light, elastic, and has a good feel. It has a smooth surface and wear-resistant surface. It has frosted, matte, and semi-matte surfaces. There are silicone-containing and silicone-free products. The product meets the environmental requirements of ROHS2.0, Reach, Halogen-free, PAHS, 23P-Free, PFOS&PFOA, etc.
Application areas:
Mainly used in the manufacture of wires and cables in the fields of wire sheaths, wire plugs, and charging pile cables.
