SODIUM SULFOCYANIDE Resistant O-Rings and Seals
Sodium sulfite, also known as sodium sulphite, is an inorganic salt that is commonly used as a food preservative and in various industrial processes. Its most common uses are as an antioxidant and bleaching agent, as well as in dyeing and photography.
When rubber is exposed to sodium sulfite, it can cause rubber to swell, become brittle, and eventually fail due to the chemical's corrosive nature. In addition, the rubber can become discolored, which can further weaken the material, leading to further cracking and damage.
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.
