Propylene oxide, also known as propene oxide, is an organic compound used in the production of polyether polyols, propylene glycol, and other chemicals used in a variety of industries. It is also used as a starting material in the production of a variety of chemicals, including propylene glycol, epichlorohydrin, ethylene oxide, and propylene glycol ethers.
When rubber is exposed to propylene oxide, it can cause swelling, embrittlement, and cracking. In addition, oxidation and discoloration of the rubber can occur, resulting in a decrease in physical and mechanical properties. The chemical can also cause rubber to become brittle and harden, leading to a decrease in flexibility and an increase in brittleness.
