Technology of polyurethane manufacturing enables to produce parts with a variety of characteristics that can not be obtained by using other materials such as rubber. Products of polyurethane are made using a complex, costly and resource-intensive technology that differs from that for rubber counterparts, so the cost of such details is higher. Making certain conditions in production facilities, special surface preparation fittings, temperature control at all stages of production, strict adherence to the proportions in the preparation of raw materials and other components of the process chain allows to manufacture the parts of superior performance.
