PHENYLENEDIAMINE Resistant O-Rings and Seals
Phenylenediamine, also known as 1,2-diaminobenzene, is an organic compound commonly used as a base in the production of nylon and other synthetic fibers, as a dye and pigment intermediate, and as a corrosion inhibitor in coolant systems. Common types of rubber failure when exposed to Phenylenediamine can include cracking, hardening, embrittlement, and discoloration. Cracking and hardening of rubber materials can occur due to chemical reactions caused by the presence of Phenylenediamine, which can reduce the elasticity of the rubber and cause it to become brittle and break. Embrittlement of rubber can occur due to the formation of new compounds caused by the reaction between the Phenylenediamine and other chemicals in the rubber, which can increase the hardness and reduce the flexibility of the rubber. Discoloration of rubber can also occur due to the presence of Phenylenediamine, which can cause the rubber to become discolored and faded.
