ENERGY ABSORBING, WATER BLOWN, RIGID POLYURETHANE FOAM |
摘要 |
The invention relates to compositions and method for producing energy absorbing, water blown, rigid polyurethane foams. The resulting polyurethane foams are low density, predominately open celled foams which exhibit a relatively constant consistency of compressive strength over deflectors. Such foams are suitable as lightweight alternatives to traditional energy absorbing applications.
