EXHAUST GASES, CONTAINING SULPHUR DIOXIDE Resistant O-Rings and Seals
Exhaust gases containing sulphur dioxide, also known as sulphur dioxide gas, are a common by-product of industrial processes. Sulphur dioxide is a colourless, pungent-smelling gas that is produced when sulphur-based fuels are burned. Common uses for sulphur dioxide include its use in laundry detergents, as an industrial bleaching agent, and as a preservative for food and beverages.
When rubber is exposed to sulphur dioxide, the rubber material can become brittle and cracked, leading to potential failure. In addition, sulphur dioxide can react with the rubber, causing it to break down into smaller components, leading to further degradation and potential failure. As sulphur dioxide is a powerful oxidizing agent, it can also cause premature aging of rubber, making it more vulnerable to failure.
