Abstract:

Lightweight insulated military footwear in a pull-on type construction was produced by integrally casting and expanding liquid polyurethane systems. The footwear developed meets the original requirements established under this program to develop a lightweight impermeable boot with insulation sufficient to provide protection for 2 hours inactivity at -20 F. The average weight of a size 10 boot is 24 ounces, as compared with 44 ounces for the standard Black insulated Cold-Wet Boot. The water absorption of the new footwear is less than 5 percent by weight. The insulative properties of the lightweight integrally cast polyurethane footwear when new are equal to or better than the standard insulated cold-wet boot there is no significant change in insulative properties after wear. The developed laboratory procedures were used to design and put into operation a pilot plant facility. Initial production of footwear indicates that the economics and processes involved may be satisfactory for the final commercialization of this new concept of lightweight insulated footwear.
