Phenolic Sulfonate is a water-soluble white powder with a pungent odor and bitter taste. It is commonly used as a surfactant, emulsifier, and preservative in a variety of products, including cleaning agents, cosmetics, food additives, and lubricants.
When rubber is exposed to Phenolic Sulfonate, it can become brittle due to the corrosive nature of the chemical. In addition, the rubber may discolor or swell as the sulfuric acid in the chemical breaks down the polymer chains of the rubber. To ensure compatibility with Phenolic Sulfonate, rubber seals should be made of a material that is resistant to the chemical, such as neoprene or fluorocarbon.
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.
