Chlorotoluene Sulfonic Acid, also known as Toluenesulfonic acid, is a colorless liquid with a pungent odor. It is used as a substituted benzene derivative in many industrial applications, such as a catalyst in organic synthesis, a surfactant, or a building block in pharmaceutical, agrochemical, and dye production. Common types of failures when rubber is exposed to this chemical can include swelling, cracking, brittle failure, and other physical changes such as discoloration and hardening. These failures can be due to an incompatibility between the rubber and acid, or due to the acid's corrosive properties. In addition, exposure to this chemical can cause rubber to lose its flexibility, making it more prone to cracking or tearing.
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.
