Dow Corning 5 is a silicone-based chemical used in a variety of industries, most commonly in lubricants and sealants. It is also known as dimethicone, polydimethylsiloxane, and polysiloxane.
When rubber is exposed to Dow Corning 5, it can cause swelling and softening of the rubber material. This can lead to cracking, tearing, and discoloration of the rubber, as well as a decrease in physical properties such as tensile strength and tear resistance. In extreme cases, the chemical can cause the rubber to become brittle and break apart.
