Isobutyl methyl ketone, also known as 2-butanone or methyl isobutyl ketone (MIBK), is a colorless, volatile liquid used as a solvent in the paint, coatings, and adhesives industries. It is also used to manufacture pharmaceuticals, flavors, and fragrances.
When exposed to isobutyl methyl ketone, rubber can become brittle, leading to cracking and failure. Additionally, it can cause swelling and oxidation, which can weaken the seals. Furthermore, it can cause discoloration, making it difficult to maintain a seal. Additionally, it can cause the rubber to become sticky or tacky, leading to a decreased life span and a weakened seal.
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.
