Abstract
A highly reactive urethane foam for RIM to produce thin-sectioned automobile trim components having good high temperature sag performance is a quasi prepolymer system in which the polyol side is based on a relatively high molecular weight polyol combined with a known highly reactive unhindered aromatic polyamine chain extender/cross linker and with conventional short chain diols/triol extenders/cross linkers and catalysts.
