BENZIDINE Resistant O-Rings and Seals

Benzidine, also known as 1,2-diaminobenzene, is an aromatic organic compound with a pungent odor. It is commonly used as a dye intermediate, as a pigment in paints and plastics, and in the production of specialty chemicals.

When rubber is exposed to benzidine, the rubber may become brittle and prone to cracking due to the acid's corrosive properties. Additionally, the rubber may become discolored due to the acid's bleaching properties. Long-term exposure can cause rubber components to become discolored, brittle, and prone to cracking prematurely. Swelling and softening of the rubber may occur due to the acid's solubility in rubber.
