SODIUM HYDROSULFITE Resistant O-Rings and Seals
Sodium hydrosulfite, also known as sodium dithionite, is a chemical compound often used as a bleaching agent, reductant, and preservative in various industries such as paper, food, and textiles. It is also used in the dyeing and finishing of fabrics, and as an additive to some products such as photographic solutions.
When rubber is exposed to sodium hydrosulfite, there is a risk of softening, cracking, and eroding of the rubber due to the chemical's corrosive properties. In addition, the rubber may become brittle and discolored, as well as degraded due to oxidation caused by the chemical. Other common types of failures that may occur include swelling, embrittlement, and an overall reduction in the rubber's flexibility.
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.
