ALUMINUM SULFATE Resistant O-Rings and Seals

Aluminum Sulfate, also known as Alum, is a widely used chemical in many industries. It is used as a flocculant in water treatment, as a coagulant in paper production, as a mordant in dyeing and printing, and as a clarification and purification agent in many other applications.

When rubber is exposed to Aluminum Sulfate, common types of failures include swelling and softening, cracking, brittleness, and accelerated aging. Swelling and softening can cause the rubber to become less elastic and reduce its ability to create an airtight seal. Cracking can occur due to the chemical's corrosive properties and cause the rubber to weaken and break down. Brittleness can cause the rubber to become brittle and crack easily. Lastly, accelerated aging can cause the rubber to degrade faster than normal.
