ALUMINUM SALTS Resistant O-Rings and Seals
Aluminum Potassium Sulfate, also known as Aluminum Potassium Sulfate Dodecahydrate, Potassium Aluminum Sulfate, and Potassium Alum, is a white crystalline compound used as a mordant in dyeing and printing textiles, as an astringent in topical skin preparations, and as a food preservative.
When rubber is exposed to Aluminum Potassium Sulfate, it can be subject to chemical attack, resulting in softening of the material, swelling, and discoloration. As the material continues to be exposed, it can experience further weakening, cracking, and ultimately failure. Additionally, the rubber may experience a decrease in tensile strength and elongation, making it less flexible and more prone to breaking.
