High Load Bearing Flexible Urethane Foams.

摘要

The load bearing properties of flexible urethane foam as a function of the formulation variables were investigated. Varying levels of a polystyrene-acrylonitrile-polyol were added to the foam systems to increase the load-bearing capabilities of the resultant materials. The formulation water level and fluorocarbon blowing agent level were also varied to provide flexible urethane foams covering a wide range of density and compressive properties. The compression set/compression deflection properties,hydrolytic stability,and aging characteristics of these foam systems were determined. (ERA citation 03:019158)
