Product Overview
Industrial Grade Trisodium Phosphate (TSP) is a strong alkaline inorganic phosphate widely used in industrial cleaning, metal surface pretreatment, boiler water softening, textile processing, and electroplating preparation. With 98–99% purity, excellent solubility, and powerful degreasing capability, TSP effectively removes oils, carbonized residues, and mineral deposits.
It is supplied as white crystalline powder or granules (Na₃PO₄·12H₂O) and delivers fast dissolution, high alkalinity, and stable performance across various industrial cleaning and water‑treatment systems. Suitable for heavy‑duty applications requiring reliable cleaning efficiency and cost‑effective operation.
