Dimethyl Ether (DME) is an organic compound commonly used in the production of pharmaceuticals, perfumes and as a fuel. It is also used as a solvent in many industries including paint, ink, and degreasing.
When exposed to rubber, Dimethyl Ether can cause degradation due to its high volatility and low boiling point. This can cause rubber to become brittle and crack, resulting in premature failure. Additionally, the low boiling point can cause rubber to lose elasticity, leading to weakened seals and gaskets.
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.
