SODIUM PHOSPHATE (DIBASIC) Chemical compatibility with O-rings, rubbers, & plastics

Sodium phosphate dibasic, also called disodium phosphate or Na2HPO4, is a white crystalline compound widely used as a buffering agent, emulsifier, and sequestrant in food processing, cleaning formulations, and chemical manufacturing. It is also used in water treatment and as a reagent in various industrial processes. In systems where disodium phosphate solutions contact O-rings, rubber seals, gaskets, and plastic components, compatibility should be evaluated to maintain sealing performance and prevent material degradation. Proper storage, safe handling procedures, and appropriate PPE are recommended to reduce irritation risks and ensure reliable operation.
