Cerous nitrate, also known as cerium nitrate, is a chemical compound composed of one atom of cerium and three atoms of nitrate. It is often used as a pigment in inks and paints, as a catalyst for certain chemical processes, and in the production of certain alloys.
When rubber is exposed to cerous nitrate, it can suffer from a variety of issues. These include discoloration, cracking, and the loss of elasticity and flexibility. In addition, the rubber may become brittle and be unable to withstand high temperatures or resist abrasion. In some cases, exposure to cerous nitrate 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.
