Patent number: 5187204Abstract: The invention relates to water blown, low density, energy absorbing rigid polyurethane foam articles which exhibit minimal springback or hysteresis characteristics. The articles produced from the foams of the present invention maintain a constant crush strength of material up to about 70% deflection and are useful in appropriate automotive applications such as side impact bolsters.Type: GrantFiled: December 27, 1990Date of Patent: February 16, 1993Assignee: BASF CorporationInventors: Michael L. Jackson, Mark A. Easterle

Patent number: 5169872Abstract: What is disclosed is a process for obtaining polyurethane foams having enhanced benefits. The invention disclosed herein provides a system flowability of the reacting foam mixture to give foams with an insulating capablity equal to the foams that are provided by chlorofluorocarbon blown system, while doing away with the chlorofluorocarbons.Type: GrantFiled: May 11, 1992Date of Patent: December 8, 1992Assignee: Dow Corning CorporationInventors: Lenin J. Petroff, James D. Thornsberry
