Key Industrial Applications
1) Detergents & Cleaning Products
Industrial STPP is a classic builder in detergent formulations. It helps:
- Soften water by binding calcium and magnesium ions
- Improve surfactant performance and overall cleaning power
- Prevent redeposition of dirt on fabrics and hard surfaces
- Stabilize pH and maintain formulation stability
2) Ceramics, Tiles & Glaze
Used as a deflocculant, dispersant and water reducer for ceramic body, glaze and slurry to improve fluidity and reduce water demand.
3) Industrial Water Treatment & Metal Processing
Acts as a sequestrant and dispersant to reduce scale formation, disperse suspended solids, and support degreasing/cleaning processes.
4) Concrete & Building Materials
Can be used in admixture systems to help control water retention and rheology, supporting better workability and performance.
