Radiation Cross-Linked Polymers for the Automotive Engine Environment 710095
Irradiation of polymers by electrons or gamma rays effects cross-linking and increases high-temperature capabilities. Cross-linking does not, however, increase resistance to chemical degradation of a polymer. Changes in formulation can inhibit high-temperature oxidative degradation. The results of tests on the high-temperature stability of a series of polyvinylchloride formulations is presented, showing that changes in formulation accompanied by radiation cross-linking improve the ability of an insulation to function in high-temperature environments.
