Sodium citrate, also known as sodium tartrate, is a widely used chemical compound in the food and beverage industries. It is used as a flavoring agent, preservative, and for buffering solutions. Common types of failures when rubber is exposed to sodium citrate include swelling, discoloration, and cracking of the rubber material. The swelling and discoloration of rubber caused by sodium citrate can lead to reduced physical properties, such as tensile strength and elongation. The cracking of rubber can cause complete failure of the rubber material, especially when the rubber is exposed to high concentrations of the chemical.
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.
