SODIUM FLUORIDE Resistant O-Rings and Seals
Sodium fluoride is also known as fluorosilicic acid and is a colorless or white powder. It is commonly used in toothpastes and other oral hygiene products, in water fluoridation, and in certain pesticide products.
When exposed to sodium fluoride, rubber can experience physical and chemical deterioration, including cracking, hardening, embrittlement, and loss of elasticity. The fluoride in the chemical can react with the rubber material and cause chain scission, resulting in a decrease in its tensile strength. Additionally, the presence of fluoride 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.
