Technologies for producing materials for shoe sole based on secondary polyurethanes

The aim of the study is to develop technologies for producing materials for shoe soles with a given level of properties based on secondary polyurethanes and a comparative analysis of their physical, mechanical and performance indicators. The object of the research is polymer materials (plates) made of primary and secondary polyurethanes. The subject of research is physical, mechanical and operational properties. The method used is a comprehensive quality assessment method. The results of the work are presented by materials for shoe soles made from primary and secondary polyurethane foam with a level of physical, mechanical and operational properties which are sufficient for making shoe soles. The field of application of the results is the footwear industry.
