Chloroethane sulfonic acid, also known as sulfonyl chloride, is a strong acid used primarily as a catalyst in the manufacturing of plastics and rubber. It is also used as a dyeing agent in fabric production and as a laboratory reagent.
When exposed to chloroethane sulfonic acid, rubber components can become brittle and cracked, with long-term exposure causing further deterioration. O-rings and gaskets are particularly prone to cracking, while softer rubbers can swell and become distorted. Chloroethane sulfonic acid can also react with metal components, leading to corrosion and further weakening of the rubber. In addition, chloroethane sulfonic acid can be absorbed by some rubber materials, resulting in a swelling and softening of the rubber.
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.
