Potassium bichromate, also known as potassium dichromate, is a chemical compound with the formula K2Cr2O7. It is commonly used in industrial processes including electroplating, photography and dyeing. It is also used in a variety of other processes such as paint manufacturing, oil refining and water treatment.
When rubber is exposed to potassium bichromate, it can be damaged or weakened due to the aggressive oxidation caused by the chemical. This can lead to cracking and swelling of the rubber, as well as discoloration, fading and embrittlement. In some cases, long-term exposure to the chemical can cause complete failure of the rubber material, resulting in the need for replacement.
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.
