Calcium chromate, also known as chromic acid calcium salt, is an inorganic compound used in a variety of industries, such as metal plating, leather tanning, and printing inks. It is also used as a corrosion inhibitor.
Exposure of rubber to calcium chromate can cause several types of failure. The chromium ions in the compound can lead to oxidation and cracking of the rubber, reducing its durability and performance. In addition, calcium chromate can cause the rubber to become brittle and crack due to its hygroscopic properties, which absorb moisture from the air and cause the rubber to swell. Finally, calcium chromate can cause the rubber to become sticky and accumulate dirt and debris, leading to further degradation.
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.
