Abstract

Ultraviolet light has been considered a main factor of natural aging threats the oil sealing’s lifetime when using outdoor. In this work, we will compare the behavior of NBR (the mostly used material for sealing) during UV aging. To analyze the characteristics of UV irradiation behavior of NBR,their surface morphology and infrared spectroscopy were measured,after the irradiated at UV environment for period time. The results showed that the surface of rubber occur more white spots and the aging began occurred.
