Sodium Methylate, also known as Sodium Methylsulfate or Methylsulfuric Acid, is an anhydrous salt compound with a wide range of industrial uses. It is used as a catalyst in the production of biodiesel, as a solvent in the production of pharmaceuticals, and in the production of detergents and cleaning products.
When rubber is exposed to Sodium Methylate, it is highly susceptible to corrosion and degradation. The salt can cause the rubber to become brittle and crack, as well as to swell and soften. Additionally, the material can lead to a decrease in the rubber's tensile strength, leading to a loss of shape and an increase in permeability.
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.
