DIETHYL SEBACATE Resistant O-Rings and Seals
Diethyl Sebacate, also known as DES, is a chemical compound used in the production of plastics and rubber products. Common uses of DES include plasticizers, lubricants, hydraulic fluids, and printing inks.
When rubber components are exposed to DES, the rubber can become overly soft and sticky. This can lead to a decrease in tensile strength and, over time, the rubber can begin to swell and degrade. Additionally, the rubber can become more susceptible to compression set and permanent deformation, leading to a decrease in sealing capabilities. Over time, the rubber can also become brittle and break down due to the presence of DES, resulting in a decrease in reliability.
