CHROMIC OXIDE Resistant O-Rings and Seals
Chromic Oxide, also known as Chromium(III) oxide, is an inorganic compound composed of chromium and oxygen. It is a dark-green or black solid which is insoluble in water and is used as a pigment in paints and varnishes. It is also used in the production of chrome plating, as well as in polishes and catalysts.
When rubber is exposed to Chromic Oxide, it can lead to the hardening and brittleness of the rubber, especially with prolonged exposure. The oxidation of the rubber can cause cracking and lead to seal failure. It can also corrode metal parts and cause a loss of elasticity.
