Dibutyl methylenedithioglycolate is also known as DBG, Tihicat, and TDG. This chemical is used as an antioxidant and stabilizer in rubber, plastics, fuel, and lubricating oils. It is also used as a metal deactivator in gasoline.
When rubber is exposed to dibutyl methylenedithioglycolate, the rubber may become brittle and crack. This is due to the chemical reaction between the rubber and the DBG, which causes the rubber to break down and degrade. Additionally, the rubber may swell, becoming softer and less resilient. The chemical can also cause the rubber to become discolored or corroded, leading to further degradation.
