Sulfur dioxide gas, wet is also known as sulfur hydroxide or sulfurous acid. It is commonly used for bleaching, in the production of paper and pulp, and for water treatment.
When exposed to sulfur dioxide gas, wet rubber materials can become corroded due to the sulfur dioxide molecules binding with the polymers in the rubber. This can cause the rubber to become brittle and crack over time. In addition, sulfur dioxide can also cause the rubber to become discolored, swell and become sticky as it reacts with the rubber’s stabilizers. Sulfur dioxide gas, wet can also corrode the rubber, which can reduce its lifespan.
