POTASSIUM BITARTRATE Resistant O-Rings and Seals
Potassium Bisulfite, also known as potassium hydrogen sulfite, is a common chemical used in the production of paper, textiles, and leather. It is also used as a food preservative and as a cleaning agent. In the rubber industry, potassium bisulfite is used as a curing agent and as a vulcanizing agent.
When rubber is exposed to potassium bisulfite, common types of failures include cracking, discoloration, and a decrease in the material's elasticity. This can cause rubber seals to become brittle and to lose their effectiveness. Additionally, exposure to high concentrations of the chemical can cause rubber seals to swell and expand, which can significantly reduce their lifespan.
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.
