Sodium tripolyphosphate (STPP) is a multifunctional compound used in the ceramic, paint, and rubber industries for its dispersing and binding properties. In ceramics, STPP improves the consistency of clay bodies and aids in the uniform dispersion of materials. In paints, it enhances stability and prevents pigment agglomeration, while in rubber processing, it serves as a dispersant and helps optimize the compounding process for improved product quality.
