Aniline sulfite, also known as aniline sulfonate, is a chemical compound used as a surfactant, dye and intermediate in the synthesis of other compounds. It is also used in the manufacture of paper, textiles and plastics. Common uses for aniline sulfite include bleaching and dyeing of paper and fabrics, and as an intermediate for producing other chemicals.
Common types of failures when rubber is exposed to aniline sulfite include swelling, cracking, and discoloration. Swelling is caused by the aniline sulfite penetrating the rubber and causing it to expand, while cracking occurs from the aniline sulfite breaking down the rubber molecules. Discoloration is caused by the aniline sulfite acting as a dye, staining the rubber a different color.
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.
