ENERGY ABSORBING POLYURETHANE COMPOSITIONS |
摘要 |
Energy absorbing polyurethane elastomer compositions having a density of from about 0.4 to about 1 gm/cc, a compression set of less than about 5% and a recovery time of from about 10 to about 100 milliseconds containing a light-weight filler are formed by reaction of a urethane-forming component comprising a compound containing at least four urethane-forming reactive sites and capable of forming stable complexes through unsatisfied urethane-forming reactive sites, an elasticizing polyol selected from the group consisting of diols and triols, and a diisocyanate in less than stoichiometric amounts. |
