POTASSIUM ALUMINUM SULFATE Resistant O-Rings and Seals
Potassium aluminum sulfate, also known as potassium alum, is a chemical compound commonly used in various industries such as tanning, dyeing, and pharmaceuticals. It is also used as a food additive and preservative.
When rubber is exposed to potassium aluminum sulfate, it can cause the rubber to become brittle and discolor, as well as swell, soften, and crack. In certain cases, the rubber may even dissolve due to the chemical's acidic properties. Additionally, prolonged exposure to this chemical can result in accelerated degradation of the rubber material.
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.
