Product Name: Phosphino Carboxylic Acid Copolymer (PCA/POCA)
CAS Number: 71050-62-9
Synonyms: Phosphino Carboxylic Acid; PCA; POCA; Phosphono Carboxylic Acid Copolymer
Phosphino Carboxylic Acid Copolymer (PCA/POCA) is an advanced water treatment polymer that integrates phosphonic acid groups into a carboxylic acid backbone. This innovative molecular structure delivers exceptional scale inhibition and dispersion properties, making it particularly effective against calcium carbonate, calcium phosphate, barium sulfate, strontium sulfate, and silica scales. With outstanding chlorine resistance and chemical stability across a broad range of water conditions, PCA/POCA represents a next-generation solution for industrial water treatment challenges.
Superior Scale Inhibition: Demonstrates excellent dispersion and inhibition properties against carbonate, phosphate, sulfate, and silica scales
Enhanced Compatibility: Shows remarkable synergies when combined with organic phosphonates, copolymers, zinc salts, and benzotriazole (BTA)
Excellent Chlorine Resistance: Maintains performance stability in chlorinated systems
Broad Application Range: Effective across wide pH and water hardness conditions
Environmentally Adaptable: Suitable for various water quality conditions and treatment scenarios

PCA/POCA is widely employed in various industrial water treatment scenarios:
Industrial Cooling Water Systems: Effective scale and corrosion inhibitor for heat exchangers, pipelines, and equipment
Oilfield Water Injection Systems: Prevents inorganic salt deposition in reinjection water systems
Membrane Protection: Used in reverse osmosis pre-treatment systems for scale prevention
Wastewater Treatment: Provides scale control in industrial wastewater treatment processes
PCA/POCA can be used as a standalone treatment at recommended dosages of 5-20 mg/L, or in combination with organic phosphonates, copolymers, zinc salts, or benzotriazole (BTA) for enhanced performance in specific applications.
Packaging: Available in 25 kg and 250 kg plastic drums, or 1000 L IBC containers. Custom packaging solutions available upon request.
Storage: Store in a cool, dry, well-ventilated area in original sealed containers. Protect from freezing and direct sunlight. Shelf life: 12 months from production date when stored under recommended conditions.
PCA/POCA is an acidic substance. Always wear appropriate personal protective equipment (PPE) including chemical-resistant gloves and safety glasses during handling. Avoid contact with skin, eyes, and clothing. In case of contact, immediately flush with plenty of water. For detailed safety information, refer to the Safety Data Sheet (SDS).
