Abstract

To produce high density polyurethane parts, a number of formulations have been developed by combining the proper materials. The formulations are easily processed, and they yield strong parts with durable surfaces which will maintain dimensional stability during extended usage. The following materials have been most successfully incorporated into the packed urethane system. LIST OF COMPOUNDS See Original page 5086.
