BENZIL Resistant O-Rings and Seals
Benzidine 3 sulfonic acid is more commonly known as Benzil. It is used as a dye and a reagent in organic synthesis, as well as a reducing agent for the production of dyes. In the pharmaceutical industry it is used as a preservative and in the production of antibiotics.
When rubber is exposed to Benzidine 3 sulfonic acid, it can cause swelling and cracking. This can reduce the rubber's flexibility and tear strength, leading to irreparable damage to the rubber material. In extreme cases, the rubber material can be completely dissolved. The rubber's resistance to the acid also varies according to its type, with synthetic rubbers such as neoprene and nitrile being more resistant than natural rubber.
