Abstract:

The objective of this program was to develop flexible foam systems which meet the specifications outlined in MIL-F-81334B AS. This report deals with the results obtained from a series of foams based on polybutadient polyol and its combinations with various types of polyether polyols. Polyol ratios, surfactant type and concentration, and catalyst type and concentration were evaluated to determine their influence on foam properties. Those foams demonstrating the most promise were measured for density, compression set, rebound, tensile strength, elongation, hydraulic fluid and hydrolytic resistance, porosity and vibration damping.
