Nitrobenzoic acid is also known as nitrobenzenecarboxylic acid and is primarily used as a precursor for the manufacture of dyes, pharmaceuticals, and other organic compounds.
When rubber is exposed to nitrobenzoic acid, it can suffer from degradation, embrittlement, and swelling. Degradation occurs when the nitrobenzoic acid reacts with the rubber’s elastomeric material, breaking down the molecular bonds and causing the rubber to become brittle and prone to cracking or tearing. Embrittlement can also occur, when the nitrobenzoic acid renders the rubber more susceptible to cracking or tearing. Lastly, the nitrobenzoic acid can cause the rubber to swell, leading to a decrease in the rubber’s physical properties and an increase in its permeability to other chemicals.
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.
