Dow Corning 44 is a polydimethylsiloxane (PDMS) silicone oil used as a lubricant and release agent in the automotive, plastics and rubber industries. It is also used as a heat transfer fluid and as an electrical insulator.
When rubber is exposed to Dow Corning 44, the oil can cause swelling or softening of the rubber. This can cause the rubber to become brittle and crack, leading to eventual failure. Additionally, long-term exposure to Dow Corning 44 can cause discoloration of the rubber, which can affect its performance and lead to premature failure.
