MA/AA Copolymer 50%ZEELCHEM™ 2000 · Manufacturer & Supplier
MA/AA Copolymer 50% is a low molecular weight maleic–acrylic copolymer scale inhibitor and dispersant. Its rigid maleic units make ZEELCHEM™ 2000 stable up to 300 °C, so it controls calcium carbonate scale and disperses iron oxide in high-pressure boilers, cooling towers and detergent formulations.

How MA/AA Copolymer 50% Works
Thermal backbone
Rigid maleic units resist chain scission and decarboxylation at high temperature.
Crystal distortion
Distorts calcium carbonate crystals so scale cannot grow into hard deposits.
Sludge dispersion
Turns scale into fluffy, free-flowing sludge removed by bottom blowdown.
Key Benefits
- Stable to 300 °C, where standard homopolymers degrade above about 160 °C
- CaCO₃ threshold inhibition plus iron oxide dispersion
- Stable in chlorinated water and with non-oxidizing biocides
- Phosphate-free, for low-phosphorus and zero-discharge treatment
- Anti-filming builder for industrial detergents and CIP cleaners

Request MSDS →MA/AA Copolymer 50%: Frequently Asked Questions
What is MA/AA copolymer and how does it prevent boiler scale?
It is a low molecular weight acrylic–maleic copolymer, stable to 300 °C. It distorts and disperses calcium carbonate and phosphate, so scale leaves the boiler as soft sludge through blowdown.
What is the recommended MA/AA dosage?
10–30 ppm active in high-pressure boilers below 65 bar, and 4–12 ppm active in cooling towers.
What is the molecular weight of ZEELCHEM™ 2000?
Optimized at 4,000–6,000 g/mol for crystal distortion and thermal resilience.
How does MA/AA compare with polyacrylic acid?
MA/AA withstands temperatures up to 300 °C, against about 150 °C for PAA, and has better calcium tolerance.
Is MA/AA stable in chlorinated water?
Yes. It has high oxidative stability in chlorinated systems and with non-oxidizing biocides.
Can MA/AA be used in detergents?
Yes, as a phosphate-free anti-filming builder in industrial dishwash detergents and CIP cleaners.
What packaging is available?
60 kg carboys, 250 kg virgin HDPE drums, 1,250 kg IBC totes and road tankers.
What is the shelf life?
24 months in sealed original containers, stored dry and ventilated at 5–40 °C.
What PPE is needed?
Chemical splash goggles, nitrile gloves and PVC workwear. Flush any contact with water.
Do you provide COA and MSDS with every batch?
Yes. Every ZEELCHEM™ 2000 consignment ships with a batch Certificate of Analysis, and the TDS and 16-section GHS Safety Data Sheet are available on request.
