POTASSIUM FERRICYANIDE Resistant O-Rings and Seals
Potassium Ferricyanide is also known as red prussiate of potash and potassium hexacyanoferrate. It is commonly used in photography, as a corrosion inhibitor, and as a non-toxic alternative to potassium cyanide. When rubber is exposed to Potassium Ferricyanide, it can cause the rubber to become stiff and brittle. This is due to the high alkalinity of the chemical, which can cause the rubber to harden and become brittle over time. Additionally, the chemical can corrode metal components that may be attached to the rubber, leading to further deterioration.
Fluorosilicone (FVMQ, FSIL)
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.
