Nitrothiophene is an aromatic heterocyclic compound with the chemical formula C4H3NS. It is also known as thionitrobenzene and is used as an intermediate in the manufacture of dyes and pharmaceuticals.
Exposure to nitrothiophene can cause swelling and softening of rubber materials. This can be compounded by the solubility of nitrothiophene in oils, which can cause the rubber to degrade further. Long-term exposure can lead to cracking and crumbling of the rubber, as well as a loss of elasticity.
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.
