SODIUM ARSENATE Resistant O-Rings and Seals
Sodium arsenate is a chemical compound with the chemical formula Na2HAsO4. It is also commonly known as disodium orthoarsenate, sodium dihydrogen arsenate and sodium orthoarsenate. It is primarily used as a pesticide in agriculture, as a water treatment agent and in the production of dyes, printing inks and photographic materials.
When rubber is exposed to sodium arsenate, it can be subject to several types of failure. The rubber can become brittle, swell, shrink, and crack due to the corrosive nature of the chemical. Additionally, the chemical can cause accelerated wear and tear of the rubber, leading to premature failure.
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.
