SODIUM TRIPOLYPHOSPHATE Chemical compatibility with O-rings, rubbers, & plastics

Sodium Tripolyphosphate, also known as STPP (Na5P3O10), is a white, crystalline inorganic compound used in various industrial and chemical applications as a detergent builder, water softener, and sequestrant. In the cleaning industry, Sodium Tripolyphosphate is employed in the formulation of laundry detergents, dishwashing detergents, and industrial cleaners, providing effective removal of dirt, grease, and stains. It is also used in water treatment processes to prevent the formation of scale and deposits. In the chemical industry, Sodium Tripolyphosphate is used as a reagent in the synthesis of various compounds and as a buffering agent in certain chemical reactions. Proper handling and storage of Sodium Tripolyphosphate are essential to maintain its quality and prevent moisture absorption. It is generally considered safe for use, although proper safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are essential to prevent irritation and other health hazards. Its versatility and effectiveness make Sodium Tripolyphosphate a valuable chemical in numerous applications.
