THIOPHOSPHORYL CHLORIDE Resistant O-Rings and Seals
Thiophosphoryl Chloride, also known as phosphorus oxychloride, is a colourless, fuming liquid with a pungent odour. It is commonly used in the manufacture of agrochemicals, pharmaceuticals, detergents, dyes and inorganic compounds. It is also used in the production of polymers, flame retardants and in the production of monomers.
Common rubber material types, such as neoprene, butyl, EPDM and natural rubber, can suffer from failure when exposed to thiophosphoryl chloride. This can include swelling, softening and cracking of the rubber material due to the chemical's corrosive and oxidizing properties. This can lead to leaks, reduced strength and inadequate sealing. Additionally, the chemical can cause embrittlement of the rubber, leading to premature failure.
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.
