CALCIUM STEARATE Resistant O-Rings and Seals
Calcium stearate is also known as octadecanoic acid calcium salt, calcium salt of stearic acid, and C18H35CaO2. It is commonly used in the production of plastics and rubber, as a lubricant for synthetic materials, and as a thickener for oils and greases.
When exposed to calcium stearate, rubber material can suffer from swelling and softening due to the acidity of the compound. This can cause rubber to become brittle and crack, leading to eventual failure of the part. Calcium stearate can also cause rubber to become stiffer and more brittle, leading to reduced flexibility and strength.
