Versatile Food-Grade Additive：Functions as an approved food preservative (E451), helping retain moisture and improve texture in seafood and meat products.
Stable Multiple Crystalline Forms：Available in Phase I, Phase II, and hexahydrate forms, with Phase II offering superior industrial stability for consistent processing and storage.
Product Description of Sodium tripolyphosphate CAS#7758-29-4
Sodium Tripolyphosphate (STPP, Na₅P₃O₁₀) is a white crystalline phosphate. It is widely used as a high-efficiency builder in detergents, accounting for nearly half of global consumption, and also serves as an excellent water softener and approved food additive E451.
Product Application of Sodium tripolyphosphate CAS#7758-29-4
Sodium Tripolyphosphate is widely used in water softening, heavy-duty laundry detergents, automatic dishwashing products, drilling fluid cleaning and liquid livestock feed supplements. It acts as an excellent peptizer, emulsifier and dispersant, and also serves as a stabilizer for hydrogen peroxide solutions.
In the food industry, it preserves seafood, meat and poultry by improving freshness and moisture retention. It is also used as a polyanion cross-linker in polysaccharide drug delivery systems and a sealant for leakage repair of farm ponds.

Dispersed PVC Resin
White fine powder
Polyvinyl chloride paste resin, also called dispersed PVC resin, is a fine white powder designed to disperse in plasticizers. Its small primary particles produce homogeneous plastisols for coating, impregnation, and casting. Applications include artificial leather, wallpaper, vinyl toys, gloves, automotive interiors, adhesives, and coatings requiring a workable paste-based processing route.![Xylene]( "Xylene")
XyleneXylene
Colorless liquid
Xylene is a clear, colorless aromatic hydrocarbon liquid with a characteristic odor. Insoluble in water but compatible with many organic solvents, it dissolves resins, oils, and rubber while providing useful evaporation behavior. It serves as a coating thinner, ink solvent, resin-processing medium, adhesive ingredient, and industrial cleaning solvent.![Ethyl acetate]( "Ethyl acetate")
Ethyl acetateEthyl acetate
Colorless liquid
Ethyl acetate is a clear, colorless ester solvent distinguished by its fruity odor and rapid evaporation. It mixes with ethanol, ether, and other organic solvents while having limited water solubility. Its solvency for oils, resins, and organic materials supports coatings, printing inks, adhesives, extraction, leather processing, and industrial cleaning.![Sodium Lauryl Ether Sulfate(SLES)]( "Sodium Lauryl Ether Sulfate(SLES)")
