Wear resistance of polyurethane

Thread Content

Polyurethane is a rapidly developing multi-functional polymer synthetic material. Polyurethane elastomers maintain high elasticity even at high hardness levels, and they possess excellent wear resistance, load-bearing capacity, and tear strength. They also have outstanding properties in terms of resistance to low temperatures, oils, and ozone. Thanks to the diversity of available raw materials and the ability to adjust their molecular structure, polyurethanes have a wide range of applications, and their fields of use are continuously expanding, with production volumes on the rise.
