POTASSIUM CYANIDE Resistant O-Rings and Seals
Potassium cyanide, also known as KCN or cyanic acid, is a highly toxic inorganic compound that is commonly used for fumigation and in electroplating, and is also used in the production of other chemicals such as acrylic fibers and certain pharmaceutical products. It is also used in organic synthesis and as a reagent in chemical reactions.
When rubber is exposed to potassium cyanide, it can cause the material to become brittle and prone to breaking, as well as softening, discoloration and cracking. The rubber can also become weakened and prone to tearing, as well as susceptible to attack from other chemicals. Additionally, the rubber can become pitted and corroded, resulting in a loss of strength and the ability to maintain a seal.
