POTASSIUM THIOSULFATE Resistant O-Rings and Seals
Potassium thiosulfate, also known as potassium hydrogen sulfate, is an inorganic compound commonly used in the chemical industry. It is used in the production of fertilizers, dyes, and medicines. It is also commonly used in water treatment, electroplating, and photography.
When rubber is exposed to potassium thiosulfate, it can cause a variety of failures. The chemical can cause the rubber to become brittle and crack, leading to premature failure. It can also cause the rubber to swell and become soft, resulting in loss of strength and elasticity. In some cases, it can cause corrosion of the rubber material, leading to further weakening. It can also cause the rubber to become discolored and faded, making it less aesthetically pleasing.
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.
