HEPTALDEHYDE Resistant O-Rings and Seals
Heptaldehyde, also known as caproaldehyde, is an organic compound commonly used as a flavoring agent and in the synthesis of other chemicals. It is also used in the production of perfumes, dyes, and pharmaceuticals. Common uses of heptaldehyde include flavoring foods, perfumes, and disinfectants.
When exposed to heptaldehyde, rubber can suffer from embrittlement and cracking due to the chemical's corrosive properties. Over time, the rubber can become stiff and less flexible, resulting in decreased performance and eventual failure. The rubber can also become discolored and develop an unpleasant odor. If the rubber is exposed to high concentrations of heptaldehyde, it can become corroded and eventually disintegrate and break down.
Fluorosilicone (FVMQ, FSIL)
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.
