Diethylene glycol, also known as DEG, is an organic compound used in various industrial applications. Common uses of DEG include the production of coolants, solvents, and lubricants.
When rubber components are exposed to DEG, they can become brittle and susceptible to cracking, leading to a decrease in sealing capabilities. Additionally, the rubber can become subject to swelling, cracking, and hardening, which can lead to a decrease in flexibility and tear strength. Over time, the rubber can also become discolored and brittle due to the presence of DEG, resulting in a decrease in reliability.
