SODIUM PHOSPHATE, DIBASIC Resistant O-Rings and Seals
Sodium phenoxide, also known as sodium phenoxide and sodium phosphate dibasic, is an inorganic compound commonly used as a preservative in food and beverage products. It is also used in industrial processes such as the manufacturing of paper, plastic, rubber, and other materials. Common uses for sodium phenoxide include as a buffer, a chelating agent, and a surfactant.
Common types of failures when rubber is exposed to sodium phenoxide include swelling and cracking of the rubber, leaching of the material, and discoloration due to oxidation. In addition, the rubber can become brittle and can suffer permanent damage if exposed to an excessive amount of the chemical.
