Dichlorodiphenyldichloroethane is also known as DDT and is an organochloride compound that was used as an insecticide for many years. It was banned in the United States in 1972 due to its effects on the environment. DDT is still used in some parts of the world, primarily in agriculture to protect crops from pests.
When rubber is exposed to DDT, it can cause swelling, softening and cracking of the rubber. The rubber can also become brittle and eventually fail. Long-term exposure to DDT can lead to permanent damage to the rubber, making it unable to perform its intended function. DDT is also known to be a surface active agent, which can cause rubber to be degraded more quickly than normal.
