Mercuric cyanide, also known as hydrocyanic acid or prussic acid, is a volatile and highly toxic compound used in electroplating, chemical synthesis, and photography. It is also used as a pesticide and in the production of some dyes.
When rubber is exposed to mercuric cyanide, it can cause the rubber to become brittle and crack due to the corrosive nature of the chemical. In addition, prolonged exposure can cause the rubber to become discolored and can lead to a breakdown of the rubber material. This can result in a loss of flexibility, elasticity, and ultimately, premature failure of the rubber.
Fluorosilicone o-rings are a hybrid of silicone and FKM resulting in great jet fuel resistance with high and low temperature performance. Also widely used in semiconductor Ashing equipment with strong resistance to oxygen plasma, FVMQ fluorosilicone o-rings also feature excellent flexibility, compression resistance, aging and sunlight resistance, and overall wide range of basic chemical resistance.
