Sodium acid bisulfate, also known as sodium bisulfate, is a common chemical used in many industries, including paper and pulp, food processing, and water treatment. Its most common use is to lower the pH of a solution or to neutralize acids.
When rubber material is exposed to sodium acid bisulfate, it can cause the rubber to become brittle, crack, and degrade over time. Exposure to this chemical can also lead to discoloration, swelling, and softening of the rubber material. Additionally, the rubber may lose its elasticity, making it less effective in sealing applications.
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.
