Sodium cyanide, also known as hydrocyanic acid or prussic acid, is a highly toxic chemical compound that is used primarily in gold mining and for the production of organic chemicals. Common uses for sodium cyanide include the production of nylon, explosives, and insecticides. Common types of failure when rubber is exposed to sodium cyanide include accelerated aging, hardening, cracking, and loss of flexibility. The chemical can also cause the rubber to become brittle and prone to tearing, as well as cause discoloration and a decrease in strength.
