Aluminum Sodium Sulfate, also known as Aluminum Sodium Sulfate Dodecahydrate, Sodium Aluminum Sulfate, and Sodium Alum, is a white crystalline compound used as a mordant in dyeing and printing textiles, as a water purification agent, and as an astringent in topical skin preparations.
When rubber is exposed to Aluminum Sodium 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.
