Abstract: The invention relates to energy absorbing, water blown, rigid polyurethane foams. The foams of the present invention are low density, predominantly open-celled foams which exhibit a relatively constant consistency of compressive strength over deflection. Such foams are suitable as light weight alternatives in traditional energy absorbing applications.
