HEDP chemical is an organophosphonic acid scale and corrosion inhibitor. HEDP is widely used as scale inhibitor, deflocculant, sequestrant and water stabilizer in cooling water systems. HEDP has a greater pH value and is even stable under high temperature. HEDP is a highly effective chelating agent and sequestering agent.
HEDP is a popular EDTA substitute. HEDP with Chelation value 500 is a substitute for EDTA.
AVA Chemicals is the leading manufacturer and exporter of HEDP. We offer the best quality HEDP with competitive prices.
