Chrome alum, also known as chromic acid, potassium dichromate, and chromium potassium sulfate, is a chemical compound commonly used in industries such as metal plating, photography, and tanning. It is also used in various chemical processes and as a mordant in dyeing textiles.
When rubber is exposed to chrome alum, it can cause a number of failures, such as cracking, hardening, discoloration, and swelling. The rubber may also become brittle, resulting in decreased flexibility and increased brittleness. In addition, chrome alum exposure can cause the rubber to become more susceptible to degradation from other environmental conditions, such as UV radiation, ozone, and extreme temperatures.
