What is a Silicone Defoamer? Complete Guide for Industrial Foam Control
Learn what a silicone defoamer is, how it works, its benefits, industrial applications, dosage, and how to choose the right foam …
The best dispersant polymer depends on the application – cooling water, RO membranes, boilers, oil and gas or mining. Here are ten widely used options.
1. Polyacrylic Acid
Main application: cooling towers, boilers. Keeps minerals suspended to prevent scale and fouling; dosed with standard metering pumps. View ZEELCHEM™ 1000 →
2. Polymaleic Acid
Main application: boilers, cooling systems. Inhibits scaling and disperses silt and clay in high-hardness, high-alkalinity water. View ZEELCHEM™ 200 →
3. Acrylic Acid–Maleic Acid Copolymer (AA/MA)
Main application: cooling water. Controls CaCO₃ and CaSO₄ scale, thermally stable up to 300 °C, disperses phosphates. View ZEELCHEM™ 3000 →
4. Acrylic Acid–AMPS Copolymer
Main application: high-hardness water. Sulfonic groups tolerate high calcium; keeps silt and inorganic particles dispersed. View ZEELCHEM™ 3100 →
5. AA/HPS Copolymer
Main application: industrial cooling. High thermal stability and fouling resistance.
6. Polyaspartic Acid (PASP)
Main application: green water treatment. Biodegradable polymer for scale and corrosion control and agricultural uses.
7. Polyepoxysuccinic Acid (PESA)
Main application: cooling towers, RO. 38–41% active, phosphorus- and nitrogen-free; typical continuous dose 1–30 mg/L.
8. Sulfonated Styrene–Maleic Anhydride Copolymer (SSMA)
Main application: high-temperature systems. Disperses iron oxide and suspended solids; clay deflocculant in petroleum.
9. Terpolymer (AA/AMPS/SSS)
Main application: power plants, refineries. Prevents CaCO₃ and calcium phosphate scale and disperses iron and zinc. View ZEELCHEM™ 7000 →
10. Sodium Polyacrylate
Main application: general industrial water. Cost-effective dispersant for suspended solids.
