【 摘 要 】

The results of studies of wear resistance and friction coefficient of polyurethane grade PT-74 filled with solid lubricant powders are presented. The abrasion patterns of the obtained polyurethanes are presented. The type and quantity of the filler providing smaller wear of a sealing element are defined. The regression analysis revealed the physical and mechanical properties of the material that have the greatest effect on wear.
