Isobutyl acetate, also known as 2-methylpropyl acetate, is a clear, colorless, volatile liquid with a sweet odor. It is used as a solvent in the food and beverage industry and for lacquers, paints, and varnishes. Common industries that use isobutyl acetate include cosmetics, pharmaceuticals, and automotive.
When rubber is exposed to isobutyl acetate, the rubber can become brittle and crack, leading to failure. Additionally, the rubber may become sticky or tacky, leading to a decreased life span and a weakened seal. The rubber may also become discolored or swollen, making it difficult to maintain a seal. Additionally, isobutyl acetate can cause swelling, which can lead to cracking and failure.
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.
