Summary

Castable Polyurethane Elastomers is a practical guide to the production of castable polyurethane articles, from simple doorstops to complex items used in the military and nuclear industries. The book shows the progression from raw materials to prepolymer production, including the chemistry and functionality of the production processes. It provides a comprehensive look at various problem-solving and processing techniques, examining the selection of different types of systems on both the micro and macro levels. It also discusses curing and post-curing operations, conveying the importance of using the correct property for the application.

Reorganized for better flow, this Second Edition:

  • Describes new methods in the processing of castable polyurethanes
  • Expands coverage of health and safety aspects
  • Brings all standards up to date

Castable Polyurethane Elastomers, Second Edition explains the production of polyurethane components, filling the gap between pure chemistry and trade information.
