Guanylurea Phosphate (GUP) is a compound whose efficacy as a flame retardant and material enhancer is rooted in its specific chemical structure and reaction mechanisms. NINGBO INNO PHARMCHEM CO.,LTD. provides insights into the molecular underpinnings of GUP's performance, highlighting its importance in various industrial applications.

The chemical formula for Guanylurea Phosphate is C2H9N4O5P, with a molecular weight of approximately 200.09 g/mol. Its structure combines the nitrogen-rich guanylurea moiety with a phosphate group. This unique combination is key to its functionality, particularly in fire retardancy. When exposed to heat, GUP undergoes decomposition. This process is complex, involving the breakdown into intermediate compounds like polyguanidine (GPP) and the release of gases such as carbon dioxide (CO2) and ammonia (NH3).

The critical phase of GUP's flame-retardant action occurs at higher temperatures. As the temperature rises further, the intermediate polyguanidine decomposes and reacts with the phosphate component to form polyphosphoric acid (PPA). PPA is a powerful dehydrating agent and acts as a catalyst for the carbonization of the substrate material. In materials like wood or bamboo filament, this catalytic action promotes the formation of a stable, insulating char layer. This char layer serves multiple protective functions: it limits heat transfer to the underlying material, restricts the flow of flammable volatile gases, and acts as a physical barrier against oxygen.

The presence of nitrogen in the Guanylurea moiety also contributes to flame inhibition through gas-phase mechanisms. During decomposition, nitrogen-containing gases can dilute the flammable gases and interfere with the radical chain reactions that propagate flames.

Furthermore, the physical form and deposition of GUP within porous materials like bamboo filament are crucial. Research shows that GUP effectively enters and lodges within the cellular structures, such as parenchyma and vessel cells. This internal deposition ensures that the flame-retardant is integral to the material, offering persistent protection.
