SULFONIC ACID Resistant O-Rings and Seals
Sulfonic Acid, also known as sulfonate or sulfuric acid, is a strong, corrosive acid that is mainly used as a catalyst in chemical reactions. It is also used in the production of detergents, soaps, paints, dyes, and fertilizers.
When rubber is exposed to sulfonic acid, it can become brittle and crack due to the acid's corrosive properties. The rubber may also experience discoloration, swelling, and shrinkage as well as a tacky surface, poor flexibility, and stiffness. Additionally, the rubber may experience a decrease in its ability to withstand extreme temperatures.
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.
