MERCURIC SULFITE Resistant O-Rings and Seals
Mercuric sulfite, also known as mercuric sulfate, is an inorganic compound composed of mercury, sulfur and oxygen atoms. It is a white crystalline solid that is soluble in water and is used as an oxidizing agent in various industries, including pharmaceuticals, photographic developing and electroplating.
When rubber comes in contact with mercuric sulfite, it can cause a variety of failures depending on the type of rubber. Generally, it can cause the rubber to become brittle, crack or break, swell or become soft and sticky. In some cases, the rubber may discolor or corrode due to the presence of the mercuric sulfite. It is important to ensure that any rubber exposed to mercuric sulfite is compatible with the chemical to avoid these types of failures.
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.
