MAGNESIUM SULFITE Resistant O-Rings and Seals
Magnesium sulfite, also known as Epsom salts, is a chemical compound composed of magnesium, sulfur, and oxygen. It has a wide variety of uses in industry, from being used as a food additive to a pH adjuster in pools, to being used in pharmaceuticals and as an industrial fertilizer.
When rubber is exposed to magnesium sulfite, the salt can cause the rubber to become brittle and harden. This can lead to cracks, chips, or other deformities in the rubber which can reduce its ability to properly seal or protect. If the rubber is exposed to high concentrations of magnesium sulfite, the rubber can become completely degraded and crumble into small pieces.
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.
