Ethylene oxide (also known as oxirane, ethylene epoxide, or ethylene glycol oxide) is a colorless, flammable gas with a sweet odor. It is commonly used in the manufacturing of other chemicals, such as ethylene glycol, ethylene glycol ethers, ethylene glycol esters, and ethylene glycol amines. It is also used as a sterilant in the medical and food processing industries.
When rubber is exposed to ethylene oxide, it may cause swelling, cracking, embrittlement, and crazing. High concentrations of ethylene oxide may also cause permanent changes in the structure of the rubber which can lead to degradation over time. Additionally, rubber compounds that contain sulfur are particularly susceptible to attack by ethylene oxide, which can cause discoloration and cracking.
