Description

Tetrakis(Hydroxymethyl)Phosphonium Chloride Urea Polymer is a high-performance, water-soluble cationic polymer widely used as a durable flame retardant and finishing agent. This compound matters for its ability to impart durable, wash-resistant flame retardancy to cellulosic textiles like cotton, meeting stringent safety standards. Industries that need it include textile manufacturing, paper production, and specialty chemical synthesis for creating fire-safe materials.

Application

• Primary application as a durable flame retardant finish for cotton and other cellulosic fabrics in apparel, home furnishings, and industrial textiles.
• Key component in the production of flame-retardant paper and paperboard for packaging and specialty applications.
• Used as a cross-linking agent and resin intermediate in thermosetting polymer formulations.
• Acts as a cationic fixative and mordant in dyeing processes to improve color fastness.
• Employed in the synthesis of specialty chemicals, including phosphonium-based biocides and surfactants.
• Application in wood treatment formulations to enhance fire resistance.
• Utilized in adhesive and coating systems requiring enhanced fire safety properties.

Quality Control

Our Tetrakis(Hydroxymethyl)Phosphonium Chloride Urea Polymer is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent performance as a flame retardant, including assay, pH, viscosity, and solids content. Certificates of Analysis (COA) documenting all key parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are kept tightly sealed when not in use to prevent absorption of atmospheric moisture. Keep away from strong oxidizing agents.
