Our industrial-grade sodium silicate liquid is widely used across
multiple sectors for its versatility and chemical stability.
Sodium tripolyphosphate is a key builder in detergent formulations. It enhances cleaning power, softens water, prevents dirt redeposition, and improves the efficiency of surfactants in powder and liquid detergents.
STPP improves the plasticity, strength, and bonding of ceramic bodies. It acts as a dispersing agent in tile, sanitaryware, and ceramic glazing applications, ensuring smooth and consistent surface finishing.
Used as a sequestrant and scale inhibitor, STPP prevents calcium and magnesium deposits and improves system efficiency in industrial and municipal water treatment plants.
STPP helps control viscosity, prevents scale formation, and stabilizes drilling fluids, making it ideal for oil exploration and mineral processing operations.
Food-grade STPP is used as a preservative, emulsifier, and moisture retention agent in seafood, meat, poultry, and dairy industries. (Only applicable for food-grade material.)
Acts as a raw material for producing various phosphate compounds, chemicals, sequestrants, and industrial formulations requiring high alkalinity and dispersion.
