Guanidine Phosphate

Guanidine Phosphate is a multifunctional organic guanidine salt compound whose unique molecular structure makes it a key functional additive across multiple industrial sectors. This product appears as a white to off-white crystalline powder with stable physical properties and a density ranging from approximately 1.48 to 1.52 g/cm³. Its solubility characteristics are distinct: it dissolves readily in water to form stable alkaline solutions; it is slightly soluble in alcohol-based solvents such as ethanol; and it is insoluble in most common non-polar organic solvents. This solubility profile offers flexibility and selectivity for application across diverse formulation systems.

The compound's core value stems from its ingenious molecular design: a phosphate group bonded to two highly reactive guanidino groups. This structure delivers multiple synergistic advantages: first, the reactive guanidino groups provide abundant reaction sites and alkalinity; second, the phosphate group confers excellent thermal stability and potential acid-donor properties; most critically, their combination generates a significant "nitrogen-phosphorus synergy effect." This synergy transcends simple performance addition. When heated or exposed to flame, it efficiently catalyzes dehydration and carbonization, forming a dense, continuous expanded carbon layer. This layer simultaneously delivers highly effective barrier and smothering effects in both the gas and condensed phases.

In the textile chemical industry, guanidine phosphate has emerged as the core component of highly efficient, eco-friendly flame-retardant finishes precisely due to this exceptional nitrogen-phosphorus synergistic mechanism. Compared to traditional halogenated flame retardants, it offers significant advantages: low smoke generation, non-toxicity, and no production of corrosive gases. When applied to cellulose fibers (such as cotton, linen, and viscose), it catalyzes the formation of a robust carbonized protective layer on and within the fiber surface. This layer effectively isolates heat and oxygen, significantly elevating the fabric's limiting oxygen index and imparting enduring flame-retardant properties. Simultaneously, it maximizes the preservation of the fabric's original soft handfeel and mechanical strength, meeting the dual demands for safety and comfort in high-end home textiles, workwear, and public-use textiles. In the papermaking industry, guanidine phosphate serves a dual role.

As a pulp flame retardant additive, it distributes uniformly within paper fibers, imparting excellent flame retardancy to paper and cardboard. This makes it suitable for producing fire-resistant packaging, decorative papers, and specialty industrial papers. Simultaneously, multiple polar groups in its molecules form strong interactions with cellulose molecules, acting as a wet strength agent to enhance the physical strength of paper in humid conditions. In the field of polymer materials, its application value extends further. Within thermosetting systems like epoxy resins and polyurethanes, guanidine phosphate not only functions as an efficient synergistic flame retardant-enhancing the effectiveness of primary flame retardants (such as aluminum hydroxide and expanded graphite) to significantly reduce total additive quantities and mitigate negative impacts on substrate mechanical properties- Its basic guanidino group also functions as a curing accelerator in certain systems, hastening resin curing reactions and boosting production efficiency.

Furthermore, in biochemistry and pharmaceuticals, its aqueous solution exhibits broad-range, highly stable pH buffering capacity, making it suitable for pH-sensitive enzymatic reaction systems or as a component of biological buffers, thereby supporting life science research. In summary, guanidine phosphate has evolved from a basic chemical raw material into a multifunctional molecular platform bridging multiple cutting-edge fields including textile safety, material flame retardancy, and biochemistry. Its eco-friendly properties and high performance perfectly align with modern industry's demand for green, sustainable, and high-performance additives. Our guanidine phosphate products undergo rigorous purification to ensure high purity and stable performance, making them the ideal choice for developing next-generation safety materials and green formulations.
