CALCIUM OXIDE Resistant O-Rings and Seals
Calcium oxide, also known as quicklime or burnt lime, is used in a variety of industrial processes including in cement production, steel manufacturing, and in the production of lime for construction materials and glass.
When rubber is exposed to calcium oxide, the primary failure mode is that of thermal degradation, as the high temperatures (over 1000°C) associated with the production of calcium oxide can lead to cracking, loss of elasticity, and eventual failure of rubber components. Additionally, calcium oxide is highly alkaline and can cause corrosion of metal parts that come into contact with it, leading to further degradation of rubber components.
