Cerous fluoride, also known as cerium fluoride, is a chemical compound composed of one atom of cerium and two atoms of fluorine. It is often used as an additive in various industries such as lubricating oils, fuel, and coolants. It is also used in certain optical materials, in catalysts for certain chemical processes, and in certain alloys.
When rubber is exposed to cerous fluoride, it can suffer from a variety of issues. These include dry rotting, cracking, loss of elasticity and flexibility, and discoloration. In addition, the rubber may become brittle and be unable to withstand high temperatures or resist abrasion. In some cases, exposure to cerous fluoride can lead to the rubber becoming completely unusable.
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.
