Abstract

The effect of the chemical structure of urethane elastomers on their wear resistance was investigated. The function the volumetric wear degree of the studied elastomers versus the content of hard segments had a pronounced form with an extremum. It was established that the best wear resistance was typical for polyurethanes and polyurethanes with some optimal content of hard segments, the level of which depended on the chemical nature of the oligomers used in the synthesis.
