Thermoplastic polyurethanes, also known as polyurethane rubber, belong to a class of elastic polymer materials with more carbamate groups (- NHCOO -) in the molecular chain. It is prepared by reaction of diisocyanate with polyether or polyester polyol with hydroxyl terminal and chain extender with low molecular weight diol. As a new kind of thermoplastic material, TPU has a wide range of hardness and can be used as soft and hard materials. It is non-toxic, pollution-free, recyclable and has developed rapidly in recent years.
TPU cable sheath wear-resisting, good mechanical strength, good luster, good elasticity at room temperature, good comprehensive performance after modification, and broad application prospects in the field of cable.
