SODIUM ARSENITE Resistant O-Rings and Seals
Sodium arsenite, also known as sodium metaarsenite, is an inorganic compound with the chemical formula NaAsO2. It has a wide range of industrial uses, such as an oxidizing agent for metal finishing, a bleaching agent for paper pulp and a reagent for testing and analyzing various chemical compounds.
When rubber is exposed to sodium arsenite, it can suffer from accelerated wear, cracking and embrittlement due to the corrosive nature of the chemical. In addition, the rubber can also become discolored, shrink and swell as it reacts with the sodium arsenite.
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.
