Description

Poly(Itaconic Acid) is a high-purity, water-soluble polymer derived from itaconic acid, a bio-based platform chemical. This versatile polymer is valued for its excellent chelating, dispersing, and water-absorbing properties, making it a sustainable alternative to petrochemical-based polycarboxylates. It is essential for manufacturers in the water treatment, personal care, and specialty chemical industries seeking effective and environmentally friendly functional additives.

Application

• Scale & Corrosion Inhibitor: A key component in industrial water treatment formulations for boilers and cooling systems.
• Dispersing Agent: Used in pigment slurries, ceramic processing, and cement admixtures to prevent particle agglomeration.
• Chelating Agent: Binds metal ions in detergent formulations, textile processing, and pulp & paper applications.
• Superabsorbent Polymers (SAPs): Serves as a co-monomer in the production of bio-based SAPs for hygiene products.
• Personal Care: Functions as a stabilizer and viscosity modifier in creams, lotions, and hair care products.
• Coating & Adhesive Additive: Improves adhesion and film-forming properties in latex paints and adhesives.
• Soil Conditioner: Used in agriculture to improve water retention and nutrient delivery in soils.

Quality Control

Our Poly(Itaconic Acid) is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including assay, viscosity, and residual monomer content. Certificates of Analysis (COA) documenting full specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture, which may affect product performance.
