INVESTIGATION OF HEAT-ACTIVATED CUSHIONING MATERIAL,
Abstract
A study was initiated to determine the feasibility of obtaining a solid urethane system which could be foamed-in-place, by the application of heat, in order to provide a cushioning material for ship-to-shore transfers. The best formulation obtained contained the following: diphenyl-4,4-diisocyanate, methacrylamide, 1,1,1-trimethylol propane, polyethylene glycol, Unice L ND, 8-hydroxy quinoline. This system foams at approx. 325F and produces a fine cellular mass 6-8 times its initial volume. The system did not, however, give satisfactory performance when coated on a supporting membrane.
