SYNTHESIS AND EVALUATION OF POLYURETHANE ELASTOMERS

Abstract

Commercially available castable, millable and/or injection moldable polyurethane elastomers were evaluated to determine their characteristics and potential use for Army applications. Experimental polyurethanes were synthesized using various polyols, polyamines and stabilizing agents in effort to improve the heat stability in the range 149 to 204 C. It was shown that retention of strength at elevated temperature can be im proved by increased functionality in the system, but only at the expense of the elastic characteristics of the material. The increased cross linking of the millable gums offers the most promise for heat resistant polyurethanes.
