Tributyl Citrate (TBC), also known as Acetyl Tributyl Citrate, is a colorless, oily liquid used as a plasticizer in a wide variety of applications. It is commonly used in the manufacturing of plastics, rubbers, and textiles.
When exposed to tributyl citrate, rubber materials can suffer from a variety of failure modes. These can include softening, embrittlement, and discoloration. Softening can occur due to the plasticizers in the chemical leaching out the plasticizers in the rubber, leading to a loss of strength and elasticity. Embrittlement can occur as a result of the chemical breaking down the polymers in the rubber, leading to a loss of elasticity. Discoloration can occur due to the chemical reacting with the rubber’s pigments.
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.
