IODINE Resistant O-Rings and Seals
Iodine, also known as Iodic Acid, is a chemical element found in trace amounts in nature. It is commonly used in pharmaceuticals, food colO-Rings, and in the synthesis of organic compounds. Common uses for Iodic Acid in industries include the production of iodophors, iodized salt, and as an antiseptic.
When rubber is exposed to Iodic Acid, common types of failure can include swelling, hardening, and cracking. If the rubber is exposed to high concentrations of Iodic Acid, the rubber can be completely dissolved. In extreme cases, Iodic Acid can cause rubber to combust or explode. It is important to use the right type of rubber when handling Iodic Acid, as some rubber materials are more resistant to the chemical than others.
