Aojin Chemical a supplier of industrial-grade Sodium Tripolyphosphate (STPP) offers STPP at wholesale prices

Industrial-grade Sodium Tripolyphosphate (STPP) is an inorganic phosphate auxiliary agent. Thanks to its superior properties—such as strong chelation for water softening, dispersion and anti-settling capabilities, emulsification and buffering, and scale inhibition for system stability—it is widely used across various industrial sectors, including detergents and personal care products, industrial water treatment, ceramic slurries, textile printing and dyeing, leather tanning, drilling muds, coatings and papermaking, and mineral processing.
Aojin Chemical is a supplier of industrial-grade STPP, offering high-purity product wholesale and full-container export services.
I. Key Product Specifications
Aojin Chemical’s industrial-grade STPP appears as a white crystalline powder or granule. Its aqueous solution is weakly alkaline; the product features good flowability and resistance to caking. CAS Number: 7758-29-4.
II. Key Industrial Applications
Aojin Chemical’s industrial-grade STPP is compatible with various industrial production processes, offering performance benefits such as detergency, water softening, dispersion, scale inhibition, and slurry stabilization. Key application scenarios include:
1. Detergent and Personal Care Industry: Core Detergent Builder
Serving as a key raw material for industrial laundry powders, industrial cleaners, degreasers, and liquid detergents, it effectively chelates calcium and magnesium ions in water to soften hard water, thereby resolving issues like poor cleaning performance and limescale residue. It also offers excellent soil suspension and anti-redeposition capabilities, enhancing detergent cleaning power and preventing powder caking; it is an essential additive in the detergent and personal care industry.
2. Industrial Water Treatment: Water Softener and Scale Inhibitor
Used in treatment systems for circulating cooling water, boiler water, and industrial process water, it inhibits scale formation and delays pipeline and equipment corrosion by chelating metal ions. This reduces water treatment operation and maintenance costs and stabilizes water circulation systems, making it suitable for factory circulating water, industrial purified water, and equipment cleaning water treatment scenarios. 3. Ceramics, Coatings, and Papermaking Industries: High-Efficiency Dispersants
Used in ceramic slurries, coating pastes, and papermaking pulp formulations, these agents significantly reduce slurry viscosity, break up powder agglomerates, and improve material fluidity and uniformity. They prevent particle settling and stratification, resulting in finer ceramic bodies, more uniform coating application, and smoother paper texture, thereby effectively increasing the pass rate of finished products.
4. Textile Printing & Dyeing and Leather Tanning Industries: Process Auxiliaries
In textile printing and dyeing, they serve as dyeing auxiliaries that stabilize the pH of the dye liquor, enhance dye dispersion and uptake uniformity, and prevent issues such as color differences and uneven dyeing (spotting). In leather processing, they act as pre-tanning agents and degreasing aids, optimizing leather pretreatment and improving the texture and quality of the finished leather.
5. Drilling, Mineral Processing, and Metallurgy Industries: Slurry Dispersants and Stabilizers
Suitable for drilling muds and mineral processing slurries, these agents provide dispersion, slurry stabilization, and anti-settling functions. They improve the fluidity and stability of the slurry, ensuring the smooth operation of drilling, mineral processing, and metallurgical processes—making them essential industrial auxiliaries in heavy industry.
