Potassium cyanate, also known as cuprocyanide, is an inorganic salt that is primarily used in the production of dyes and pigments, as well as in the manufacture of plastics and rubber. It is also used in chemical analysis, as a reagent in chemical processes, and as a catalyst for certain types of chemical reactions.
When rubber is exposed to potassium cyanate, it can cause a range of types of failure, from softening and cracking of the material to hardening, discoloration and a reduced ability to maintain a seal. The material can also become brittle and prone to breakage, and the rubber can be weakened and become prone to tearing. In addition, the rubber can become susceptible to attack from other chemicals, and the surface of the material can become pitted and corroded.
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.
