Sulphuryl chloride, also known as sulphur dioxide, is a colourless gas with a sharp, pungent odour. It has a variety of uses in industry, including the production of sulfuric acid, the manufacture of paper, and the bleaching of textiles. It is also used as a preservative and disinfectant in food, and as an insecticide in agriculture.
Common rubber material types may experience failure when exposed to sulphuryl chloride. These failures include accelerated aging, cracking, swelling, and hardening. The chemical can also cause rubber to become brittle and prone to cracking or tearing, and can degrade the rubber’s physical properties. In extreme cases, the rubber may become brittle and break apart. In addition, sulphuryl chloride can cause rubber to lose its elasticity, making it prone to cracking or tearing if stretched.
