A comprehensive introduction to polyurethanes, their processing and applications. This family of materials is probably the most versatile group of plastics now available. The wide variety of forms - from flexible and rigid foams to rubber-like elastomers - has made polyurethanes probably one of the most commonly used plastics. A general view of polyurethanes is given first, followed by information on basic chemistry, the machinery and techniques for manufacture and the chemical raw materials available. The properties, uses and advantages of a wide variety of polyurethane products are examined with special attention to rigid and flexible foams. An extensive glossary and tabulated data on the properties of raw materials and typical end products makes consultation of the book quick and simple. Information is provided for both the materials manufacturer and the designer. Numerous illustrations make clear the technology at all stages.
