Mercury chloride, also known as calomel or mercuric chloride, is a chemical compound with the formula Hg2Cl2. Common uses for mercury chloride include electroplating and electrorefining, as well as use in medical and industrial disinfectants. Mercury chloride is also used in some fungicides and as a catalyst in organic synthesis.
When rubber is exposed to mercury chloride, it can cause the rubber to swell, which can lead to cracking, tearing, or loss of elasticity. Additionally, mercury chloride can corrode metal parts, leading to further failure of the rubber seal. Long-term exposure to mercury chloride can also cause the rubber to become brittle, leading to fatigue cracking. Mercury chloride can also cause chemical burns to rubber due to its highly corrosive nature.
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.
