Calcium hypochlorite, also known as bleaching powder, is a chemical compound used for water purification, disinfection, and bleaching. It is commonly used in swimming pools, food production, and wastewater treatment. Common types of failures when rubber is exposed to calcium hypochlorite are ozone cracking, embrittlement, and accelerated aging. Ozone cracking is caused by the oxidation of the rubber due to the presence of ozone in the air. Embrittlement is caused by the rubber becoming brittle due to the chemical reaction of the rubber with calcium hypochlorite. Accelerated aging is caused by the rubber becoming brittle due to the breakdown of the rubber by calcium hypochlorite over time.
