Mercurous nitrate, also known as mercuric sulfite, is a white crystalline solid that is widely used in the manufacturing of batteries, matches, and fertilizers. It is also used in the processing of photographic films and in electroplating.
When exposed to mercurous nitrate, rubber can suffer from a phenomenon known as “blistering.” This occurs when the chemical reacts with the rubber, causing localized swelling and the formation of gas pockets. The gas pockets can weaken the rubber, leading to eventual failure. In addition, the rubber may become brittle and eventually crack due to the chemical reaction.
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.
