AMMONIUM PHOSPHITE Resistant O-Rings and Seals
Ammonium Phosphite, also known as Ammonium Hydrogen Phosphite, is a chemical commonly used in many industries, such as agriculture, food processing, and pharmaceuticals. It is used as a fertilizer, a food preservative, and a preservative.
Exposure of rubber to Ammonium Phosphite can cause a number of issues, including physical degradation, discoloration, and cracking. Physical degradation can occur due to the chemical's acidic nature; discoloration can occur due to the chemical's bleaching properties; and cracking can occur due to the chemical's hygroscopic properties. In addition, rubber materials can be subject to swelling, softening, and other forms of deterioration if exposed to high concentrations of Ammonium Phosphite for an extended period of time.
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.
