CALCIUM SULFAMATE Resistant O-Rings and Seals
Calcium sulfamate, also known as calcium sulfamethoxazide, is an inorganic compound used mainly in the leather, paper, and food industries. It is used as a tanning agent, a sizing agent, and a bleaching agent.
When exposed to calcium sulfamate, rubber material can suffer from embrittlement and cracking. The compound can break down the rubber's molecular structure, leading to decreased elasticity and strength. In addition, calcium sulfamate can cause the rubber to become brittle and crack, leading to eventual failure of the part.
