Dimethyl Formaldehyde (also known as Formalin) is a highly colorless, organic compound commonly used as a disinfectant, preservative and as a component in some manufacturing processes. It is commonly used in healthcare, agriculture, food processing and in the production of plastics and resins.
When exposed to rubber, Dimethyl Formaldehyde can cause oxidation and degradation, resulting in a loss of elasticity and strength. The compound can also cause rubber to become brittle and crack, leading to premature failure. Additionally, the compound can cause rubber to become discolored, leading to an unsightly appearance.
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.
