Description

Pentadecasodium Tridecametaphosphate Oxide is a specialized inorganic polyphosphate salt with a complex, high-molecular-weight structure. This compound is valued in industrial processes for its powerful sequestering, dispersing, and water-softening capabilities. It serves as a critical performance additive for manufacturers in sectors such as water treatment, detergent formulation, and industrial cleaning, where controlling metal ions and preventing scale is essential.

Application

• Industrial Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems.
• Detergent & Cleaner Manufacturing: Functions as a superior builder and sequestrant in heavy-duty industrial and institutional cleaning formulations.
• Pulp & Paper Processing: Used as a dispersant and chelating agent to control metal ions and improve bleaching efficiency.
• Textile Processing: Serves as a water softener and dispersant in scouring, bleaching, and dyeing baths to ensure uniform results.
• Ceramic & Clay Production: Employed as a deflocculant to control viscosity and improve the workability of slips and slurries.
• Oilfield Applications: Utilized in drilling muds and completion fluids as a thinner and scale preventative agent.
