Description

Boric Acid (H3BO3), Complex With Polyvinyl Alcohol is a specialized coordination compound formed between boric acid and the polymer polyvinyl alcohol (PVA). This complex is engineered to leverage the flame-retardant and antiseptic properties of boric acid within a stable, polymeric matrix, offering controlled release and enhanced material compatibility. It is a critical functional additive for industries requiring modified material properties, such as improved flame resistance, barrier performance, or controlled biocidal action. Key sectors utilizing this advanced material include specialty adhesives, coatings, textile finishing, and polymer processing.

Application

• Flame Retardant Additive: Used in coatings, adhesives, and polymer formulations to impart fire resistance.
• Crosslinking Agent: Functions in polyvinyl alcohol-based systems to modify film properties, enhance water resistance, and improve mechanical strength.
• Textile Finishing: Applied to fabrics to provide flame-retardant and anti-microbial finishes.
• Adhesive Formulation: Serves as a modifier in PVA-based adhesives to control viscosity, set time, and bond performance.
• Barrier Coatings: Incorporated into packaging or paper coatings to enhance barrier properties against moisture and gases.
• Controlled-Release Matrix: Utilized in agricultural or industrial applications for the slow release of boric acid.

Quality Control

Our Boric Acid-Polyvinyl Alcohol Complex is manufactured under a strict quality management system. Each batch is tested to ensure consistent composition, purity, and performance characteristics relevant to its application. Key parameters monitored include boron content, complexation efficiency, and polymer characteristics. A Certificate of Analysis (COA) detailing batch-specific results is provided with every shipment to guarantee traceability and compliance with your specifications.

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); the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect performance. Keep away from incompatible materials.
