TPU is a high-performance polymer material that is polymerized through the reaction of diisocyanates, macromolecular polyols, and chain extenders. It has the following characteristics: 1. Excellent performance: Wide hardness range (60HA-85HD), wear resistance, oil resistance, low temperature resistance, good elasticity. 2. Widely used: for shoe materials, cables, consumer electronics, automotive, medical and other fields. 3. Environmental friendliness: Halogen free flame retardant TPU can replace soft PVC and meet environmental requirements
