CALCIUM CYANIDE Resistant O-Rings and Seals
Calcium cyanide, also known as cyanogen calcium, is an inorganic compound used in a variety of industries, such as mining and metallurgy, as a cyanide source for the extraction of gold and silver.
Exposure of rubber to calcium cyanide can lead to several types of failure. The cyanide ions in the compound can lead to oxidation and cracking of the rubber due to their corrosive properties. In addition, calcium cyanide can cause the rubber to become brittle and crack due to its hygroscopic properties, which absorb moisture from the air and cause the rubber to swell. Finally, calcium cyanide can cause the rubber to become sticky and accumulate dirt and debris, leading to further degradation.
