What Is Thermoplastic Polyurethane TPU?

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.

The characteristics of TPU include

Wide hardness range: The hardness of TPU can be adjusted by changing the raw material ratio, and good elasticity and wear resistance are maintained throughout the hardness range.

High mechanical strength: TPU products have outstanding load-bearing capacity, impact resistance and shock absorption performance.

Cold resistance: TPU can still maintain good elasticity and flexibility at extremely low temperatures.

Good processing performance: TPU can be processed by thermoplastic materials such as injection molding, extrusion, blow molding, and calendering, which is suitable for mass production.

Oil resistance, water resistance, and mildew resistance: TPU has good resistance to oils and many solvents.

Good recyclability: TPU waste can be recycled and reused.

Weather resistance: TPU has excellent resistance to high-energy rays.

The application of TPU is very wide, including but not limited to:

Shoe materials: sports shoe logo, air cushion, hiking shoes, etc.

Clothing: waterproof and breathable fabrics, medical clothing, etc.

Medical: surgical gowns, caps, shoes, hospital mattresses, etc.

Defense products: aircraft fuel tanks, weapons sealing coatings, etc.

Sports goods: football surface, inflatable bed, ski gloves, etc.

Industrial goods: outer sheath materials for wires and cables, hoses, etc.

Other uses: mobile phone keys, plastic inflatable toys, furniture fabrics, etc.

With the advancement of technology and market demand, new uses and new products of TPU materials continue to emerge, making it one of the fastest-growing thermoplastic materials. The environmental protection characteristics and high performance of TPU make it an ideal substitute for PVC and rubber in many fields. With the increasing attention to environmental protection and sustainability, TPU, as a green and environmentally friendly material, has broad application prospects.
