- Abstract
ificial weathering tests on ethylene-propylene-diene monomer (EPDM) rubber were conducted in a fluorescent UV/condensation weathering equipment (E-UV environment) and a xenon lamp light exposure and weathering equipment (E-Xe environment) for different time periods. The correlation between E-UV and E-Xe environment was investigated by using crosslink density as criteria. Thermal gravimetric analysis (TGA) was used to evaluate the thermal stability of EPDM. The fracture morphology was monitored by scanning electron microscope (SEM). The results showed that the correlation between E-UV and E-Xe environments can be expressed as: $$ t_{\text{Xe}} = - 7.4818 + 1.1837t_{{{\text{Xe}}{-}{\text{UV}}}} , $$ where the correlation coefficient R is 0.9856. The thermal stability of EPDM did not deteriorate dramatically on exposure to the two artificial weathering environments. An oxidation layer was formed after 90 days of exposure.
