Polyurethane is a universal polymeric material with multiple properties thanks to which it is possible to obtain countless products and make various modifications.
Today, polyurethane successfully replaces various types of rubber, as well as plastics and metals. It has unique properties, among which its elasticity and high resistance, even to wear, stand out. The wear resistance of polyurethane is 3 times that of conventional rubber. In addition, polyurethane surpasses rubber in terms of tensile strength by 2.5 times (specifically, the data reports 35 MPa for polyurethane and 12.7 MPa for rubber).
Polyurethane resists a compressive pressure of 105 MPa and can be used in a wide range of different temperatures, from 50 degrees below zero to 140 degrees above zero.
The production of polyurethane compounds is a complex and energy-intensive technological process: two components, polyol and isocyanite, are first mixed and then heated; the polyesteramines are finally added to the compound obtained. This process requires the use of expensive equipment.
Italy, Germany, France, Russia, Australia and the United States have the necessary technology for the production of raw materials used in the production of polyurethane.
