Nitrotoluene, also known as nitrous acid, is widely used in the manufacture of explosives, dyes, and pharmaceuticals. It is also used as a fuel additive and as a solvent in the rubber and plastics industries. Common types of failures when rubber is exposed to nitrous acid include swelling, cracking, and hardening of the rubber due to oxidation. The rubber may also become brittle and may eventually fail completely due to the acid's corrosive properties.
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.
