Types of Polyepoxysuccinic Acid

PRODUCT LIST

Types of Polyepoxysuccinic Acid

  • 100% Biodegradable: Unlike many synthetic polymers, PESA is fully biodegradable, making it ideal for systems with strict discharge limits.
  • Green & Phosphorus-Free: Helps facilities comply with environmental laws prohibiting phosphorus discharge into local water bodies.
  • Superior Scale Inhibition: Particularly effective against Calcium Carbonate (CaCO3), Calcium Sulfate (CaSO4), and Barium Sulfate (BaSO4).
  • Wide Compatibility: Works synergistically with other water treatment chemicals and maintains stability in high-alkalinity, high-hardness, and high-pH environments.

Polyepoxysuccinic Acid Uses

  • Scale & Rust Prevention: Stops mineral buildup and corrosion in pipes, boilers, and heat exchangers.
  • Water Balancing: Controls hardness and pH levels to ensure high-quality water for industrial use.
  • Cooling Efficiency: Keeps cooling towers clean, preventing scale on heat transfer surfaces to save energy.
  • Oilfield Reliability: Protects pumps and pipelines from clogging, reducing expensive maintenance and downtime.
  • Enhanced Cleaning: Acts as a powerful additive in industrial detergents to strip away stubborn stains and minerals.

Polyepoxysuccinic Acid Uses

Yes. PESA is a direct green alternative for scale inhibition. While it is phosphorus-free, it often matches or exceeds the performance of phosphonates in systems with high calcium carbonate levels. Our engineers can provide a dosage conversion chart based on your specific water analysis.

Absolutely. One of PESA’s greatest strengths is its performance in alkaline conditions (pH 8.5–12.0), where many other antiscalants lose efficiency or precipitate out.

PESA is highly biodegradable according to OECD standards. This significantly reduces the environmental impact of blowdown water and helps avoid costly wastewater treatment surcharges.
