Antimony pentachloride, also known as sesquichloride of antimony, is a chemical compound with the formula SbCl5. It is used in many industries as an oxidizing agent, catalyst, and in the production of other antimony compounds. Common types of rubber failure when exposed to antimony pentachloride include cracking, discoloration, and brittle degradation. The cracking can be caused by the chemical's corrosive nature, while the discoloration and brittle degradation are caused by the chemical's reactivity with the rubber's polymer chains.
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.
