Octanal, also known as caprylic aldehyde, is a fatty aldehyde used in a variety of industries including cosmetics, fragrances, and food production. It is also used in the production of detergents, oils, and plastics.
When rubber is exposed to octanal, it is prone to plasticization and hardening due to the compound's strong oxidation potential. This can lead to seal failure and possible leakage as the rubber becomes more brittle and prone to cracking. Additionally, the compound can cause swelling of the rubber, leading to further seal 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.
