Abstract:

Cast urethane-urea elastomers were prepared from blends of high molecular weight polyethers and polytetramethylene ether glycols which meet the mechanical strength, compression set at 100C and low temperature flexibility at -55C -67F requirements of the contract. This leaves only the ASTM No. 3 oil resistance requirement to be satisfied. Work has continued on evaluation of various diisoycanates, diamines, and low molecular weight chain extenders in the elastomer formulations. Also, a 4700 molecular weight polyether diol was evaluated. Author
