Scale Inhibitors

scale inhibitors

AA/AMPS Copolymer Scale Inhibitor

Acrylic acid / AMPS copolymer for scale inhibition and iron oxide dispersion. Excellent performance in high-temperature, high-TDS systems where phosphonates alone are insufficient.

scale inhibitors

ATMP (Amino Trimethylene Phosphonic Acid)

CAS: 6419-19-8

Nitrogen-containing phosphonic acid with excellent CaCO3 and CaSO4 scale inhibition. Better calcium tolerance than HEDP in high-hardness systems.

scale inhibitors

DTPMP (Diethylenetriamine Penta Methylene Phosphonic Acid)

CAS: 15827-60-8

High-performance phosphonic acid with 5 phosphonate groups for maximum scale inhibition. The strongest organophosphonate for BaSO4 and SrSO4 scale in oilfield applications.

scale inhibitors

EDTMPS (Ethylene Diamine Tetra Methylene Phosphonic Acid Sodium)

CAS: 1429-50-1

Sodium salt of EDTMP with good solubility and chelation properties. Effective scale inhibitor and chelating agent for circulating cooling water systems.

scale inhibitors

HEDP (1-Hydroxyethylidene-1,1-Diphosphonic Acid)

CAS: 2809-21-4

Organophosphonic acid scale and corrosion inhibitor for cooling water, boiler water and oilfield systems. Effective against CaCO3 and BaSO4 scale at low dosage.

scale inhibitors

HPMA (Hydrolyzed Polymaleic Anhydride)

CAS: 26099-09-2

Phosphorus-free polymer scale inhibitor and dispersant. Environmentally preferred alternative to phosphonate-based inhibitors in discharge-sensitive applications.

scale inhibitors

PBTCA (2-Phosphonobutane-1,2,4-Tricarboxylic Acid)

CAS: 37971-36-1

Chlorine-stable phosphonate scale inhibitor that maintains performance in chlorinated cooling water systems. Unlike HEDP/ATMP, PBTCA is not degraded by oxidizing biocides.

scale inhibitors

RO Membrane Antiscalant — General Purpose

Broad-spectrum antiscalant for RO/NF membrane systems. Prevents CaCO3, CaSO4, BaSO4 and silica scale at recovery rates up to 85%.

scale inhibitors

Sodium Hexametaphosphate (SHMP)

CAS: 10124-56-8

Inorganic polyphosphate for scale prevention in drinking water systems and food processing. Also used as a sequestrant for iron and manganese in water treatment.

scale inhibitors

Zinc Phosphate Corrosion & Scale Inhibitor

Combined zinc-phosphate formulation for simultaneous corrosion and scale control in open recirculating cooling water systems. Forms protective film on metal surfaces.
