Abstract
The invention covers a method for making reaction injection molded polyurethanes of improved properties. The elastomeric products having superior heat distortion and tear properties comprise the reaction product of an aromatic polyisocyanate, a high molecular weight polyol and a chain extending agent. Said polyol providing said improved properties is a poly(oxybutyleneoxyethylene) glycol having a molecular weight range of about 2,000-6,000. The polyurethane elastomer is prepared by injecting the above three agents through a RIM head into a mold cavity of the desired configuration. Reaction injection molded elastomers are useful as molded articles of commerce including, but not limited to, vehicle body parts.
