- White granular or powder with density of 0.35-0.90 g/cm³ and melting point of 622°C
- Easily soluble in water with alkaline aqueous solution (pH 9.7 for 1% solution)
- Gradually hydrolyzes into phosphite in water with excellent metal ion complexation ability
- Forms soluble complexes with calcium, magnesium, iron and other metal ions
- Acts as an inorganic surfactant with properties similar to organic surfactants
- Cost savings: 1 ton of STPP equals 1.2 tons of common phosphate efficiency
- Improved efficiency: Reduces ceramic slurry flow time from 120s to 72s
- Risk control: Complete REACH pre-registration document support
- High purity (96%): Ensures optimal industrial application performance
- Stable supply: Capable of fulfilling large volume orders consistently
- Technical support: Professional guidance for application solutions
- Outstanding chelation: 1g STPP chelates ≥200mg calcium ions (35% more efficient than traditional phosphates)
- Multi-form adaptation: Available as powder (0.1-0.5mm) or granules (0.5-1.2mm) with customizable sizes
- Composite functionality: Combines dispersion, emulsification and pH buffering with surfactant synergy
- Avoid inhaling dust - use protective masks and gloves during handling
- Keep away from strong acids to prevent violent reactions
- In case of contact with eyes/skin, rinse immediately with water and seek medical attention
- Store in cool, dry place in sealed containers to prevent moisture and caking
- Shelf life: 24 months
