Chrome alum, also known as chromium potassium sulfate, is a chemical compound used in a variety of industries, including leather tanning, dyeing, and printing. It is also used as a mordant in textile processing as well as a corrosion inhibitor in metalworking.
When rubber is exposed to chrome alum, it can cause the rubber to become brittle and lose its elasticity, leading to cracking and premature failure. Additionally, chrome alum can cause the rubber to become sticky and lose its adhesive qualities, making it difficult to maintain an effective seal. Exposure to chrome alum can also cause discoloration of the rubber, making it more difficult to identify if the seal is working properly.
