Abstract
The basic chemical and physical proper ties of microcellular urethane are described. The methods of processing and the produc tion sequence are outlined. The ability of microcellular urethane to replace rubber and other materials in auxiliary springs, damping devices, and seals is discussed. A number of examples of current applications, particularly in the automotive industry, are given.
A direct comparison between the compres sion, shear, cold flow, permanent set, fatigue strength, and effect of temperature on natural rubber and microcellular urethane is given.
