Abstract
The paper presents the results of tribological tests of thermoplastic polyurethanes (TPU) and rubber based on nitrile butadiene rubber (BNR) on rigidly fixed silicon carbide and free abrasive. The influence of pressure and sliding speed on the coefficients of friction is shown. For Elastollan 1164, the coefficient of friction and mass loss were 0.2-0.3 and 0.028 g, which is 5-7 times lower than for BNR.
