The relationship between abrasive wear behavior and chemical structure of polyurethane urea elastomers

摘要

The relationship between abrasive wear and the chemical structure of molded polyurethane urea elastomers based on polyethers and polyesters was investigated. The regularities of the influence of the hard blocks content in the polymer chain on the abrasive resistance of the studied elastomers in a wide range of their hardness values were revealed.
