CALCIUM HYPOPHOSPHITE Resistant O-Rings and Seals
Calcium hypophosphite, also known as calcium dihydrogen phosphate, is a chemical compound used as a food supplement, fungicide, and in the production of some industrial chemicals. Common types of failures when rubber is exposed to calcium hypophosphite are ozone cracking, embrittlement, and accelerated aging. Ozone cracking is caused by the oxidation of the rubber due to the presence of ozone in the air. Embrittlement is caused by the rubber becoming brittle due to the chemical reaction of the rubber with calcium hypophosphite. Accelerated aging is caused by the rubber becoming brittle due to the breakdown of the rubber by calcium hypophosphite over 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.
