SULFANILIMIDE Resistant O-Rings and Seals
Sulfanilimide, also known as 4-Aminobenzenesulfonamide, is an organic compound used as a reagent in organic synthesis, a dye intermediate, and a corrosion inhibitor. It is also used in the production of pharmaceuticals, in the textile industry, and as a food additive.
When rubber is exposed to sulfanilimide, it can become brittle and break apart, leading to seal failure. Additionally, the sulfanilimide can corrode the metal components found in rubber seals, leading to further failures. Furthermore, sulfanilimide can cause rubber to swell and soften, leading to decreased flexibility and seal integrity. Additionally, sulfanilimide can cause the rubber to discolor or fade over time.
