MA/AA Copolymer 50%
Low molecular weight Copolymer of Maleic and Acrylic Acid engineered for extreme thermal stability (up to 300°C), superior calcium carbonate scale threshold inhibition, and iron oxide dispersion in high-pressure boilers and cooling water.
Technical Specification Target
Thermal Stability & High-Pressure Boiler Protection
Standard homopolymers degrade above 160°C. ZEELCHEM™ 2000 incorporates rigid maleic repeating units into the acrylic backbone, providing thermal resistance up to 300°C without chain scission or decarboxylation.
It exhibits dual crystal distortion and threshold dispersion, rendering hard scale precipitants into fluffy, free-flowing sludges easily evacuated via boiler bottom blowdown.

Frequently Asked Questions: MA/AA Copolymer 50%
Expert technical answers on dosing, chemistry, handling, and application performance.
Q1. What is MA/AA Copolymer 50% and how does it prevent boiler scale?
MA/AA Copolymer (CAS 26677-99-6) is a low molecular weight acrylic-maleic copolymer offering thermal stability up to 300°C and superior dispersion of calcium carbonate and phosphate in high-pressure boilers.
Q2. What is the recommended dosing of MA/AA Copolymer?
In high-pressure steam boilers (<65 bar), dosing is 10.0 to 30.0 ppm active. In industrial cooling towers, 4.0 to 12.0 ppm active is applied.
Q3. What is the molecular weight distribution of ZEELCHEM™ 2000?
ZEELCHEM™ 2000 is synthesized with an optimal molecular weight of 4,000 to 6,000 g/mol for maximum crystal distortion and thermal resilience.
