POTASSIUM SULFATE Resistant O-Rings and Seals
Potassium sulfate, also known as sulfate of potash, is a colorless, odorless salt that is used in various industries. Common uses include as a fertilizer, in the production of glass, and in the production of soaps and detergents.
Common types of failures that occur when rubber is exposed to potassium sulfate include cracking or hardening of the rubber, discoloration, and premature degradation of the rubber material. This is caused by the potassium sulfate reacting with the rubber material and causing the rubber to become harder and less pliable. Additionally, the potassium sulfate can react with oxygen, which can cause discoloration and premature degradation. The potassium sulfate can also corrode the rubber material, which can lead to further cracking, hardening, and premature degradation.
