Interpenetrating polymer networks IPNs elastomers and foams composed of polyurethanes and epoxies were prepared by the simultaneous technique. Fillers and plasticizers were incorporated by random batch mixing. The PUepoxy ratio was varied. Enhanced energy absorbing abilities were demonstrated by the dynamic mechanical spectroscopy results broad and high tan delta behavior as a function of temperature. This was reflected in the mechanical and acoustical energy absorption of the foams. The effects of fillers and plasticizers were mixed.
