TRIPOTASSIUM PHOSPHATE Resistant O-Rings and Seals

Tripotassium phosphate, also known as potassium phosphate tribasic, is an inorganic chemical compound that is widely used in the food industry as a preservative, a texturizer and an emulsifier. Its other common applications include being used as a fertilizer, a buffering agent, a dispersant, a thickener and a chelating agent in various industrial processes.

When exposed to tripotassium phosphate, rubber materials may show signs of discoloration or erosion. The chemical has the potential to degrade the rubber over time, leading to cracks and other structural damage. The material's resistance to this chemical is also likely to be reduced, resulting in increased permeability that can allow other compounds to penetrate the rubber. Additionally, the rubber may become more brittle and prone to breakage.
