Ammonium Dichromate, also known as Ammonium Bichromate, is an inorganic compound used in photography, wood staining, and as a mordant in dyeing. It is also used in pyrotechnics as an oxidizing agent and in the production of some specialty chemicals. Common types of failures when rubber is exposed to Ammonium Dichromate include cracking, hardening, embrittlement, and discoloration. This is due to the compound’s strong oxidizing properties, which can cause the rubber to degrade over time. Rubber materials that are exposed to this compound must be specially formulated to resist its corrosive and reactive effects.
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.
