Sodium fluorosilicate is also known as sodium silicofluoride and is a white powder with a slight odor. It is commonly used as a water fluoridation agent, in some insecticides and rodenticides, and in the production of brick and ceramics.
When exposed to sodium fluorosilicate, rubber can suffer from physical and chemical deterioration, including cracking, brittleness, embrittlement, and loss of elasticity. The fluorosilicate can react with the rubber material and cause chain scission, resulting in a decrease in its tensile strength. Additionally, the presence of fluorosilicate in the rubber can lead to accelerated wear and tear of the rubber material. In extreme cases, the rubber can become brittle and more prone to cracking, leading to higher failure rates.
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.
