Sodium Bisulfide, also known as Sodium Hydrosulfide, is a strong reducing agent and corrosion inhibitor used in a variety of industries including chemical manufacturing, water treatment, and oil refining. It is also used in the production of rubber and plastics.
When rubber is exposed to Sodium Bisulfide, the rubber material can become brittle and degrade over time. This can cause premature failure of the rubber seal, resulting in leaks and breaks. Additionally, the rubber material may become discolored or swell up when exposed to Sodium Bisulfide, both of which can cause the seal to be ineffective.
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.
