Isocyanate-Based Structural Foams 720476

Over the past few years there has been a growing interest in the applications of isocyanate-based structural foams (Dermathane). Molds and tooling are critical to making a good article. Experience is the principal teacher in this area of technology. An analysis of various toolings and applications tells what is necessary and what is unnecessary.
Density is well-known as the most important variable when strength is considered. However, when sandwich-like structures are involved, the analysis for strength becomes more complicated. This paper includes all the processing and design information necessary for using Dermathane at the optimum strength and economy.
