Thermal Aging Behavior of Ethylene Propylene Diene Monomer (EPDM) Rubber

Article Preview

Abstract:

Ethylene propylene diene monomer (EPDM) rubber was exposed to an accelerated thermal aging environment produced by an air-circulating oven for different time periods. The changes of thermal stability and chemical structures of EPDM were monitored by thermo-gravimetric analysis (TGA), Attenuated total reflection-fourier transform infrared spectroscopy (ATR-FTIR) and X-ray Photoelectron Spectroscopy (XPS). The results showed that the accelerated thermal aging environment did not obviously affect the thermal stability of EPDM. FTIR and XPS confirmed the formation of hydroxyl, carbonyl and ester groups in the test environment.
