Tartaric acid is also known as dihydroxybutanedioic acid and is commonly used as an antioxidant, acidulant, and flavoring agent. Common uses include being an additive in wine, as an acidulant in food and beverages, and as a preservative in some pharmaceuticals.
When exposed to tartaric acid, rubber materials can suffer from a variety of issues. The acid can cause the rubber to become brittle over time, leading to cracking, hardening, and eventual failure. The acid can also cause discoloration, swelling, and softening of the rubber, leading to a decrease in performance and strength. In extreme cases, the acid can react with the rubber, leading to a breakdown of the material itself.
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.
