Description

Guanylurea Phosphate is an organophosphorus compound that serves as a highly effective and versatile intermediate. Its primary commercial value lies in its role as a key precursor for synthesizing halogen-free, nitrogen-phosphorus intumescent flame retardants, which are increasingly demanded for safer materials. This product is essential for manufacturers in the polymer, textile, and construction industries seeking to enhance the fire safety of their products while meeting stringent environmental regulations.

Application

• Primary use as a flame retardant precursor for the synthesis of guanidine phosphate and melamine polyphosphate-based systems.
• Formulation of intumescent fire-retardant coatings for steel structures, wood, and plastics.
• Production of flame-retardant polyurethane foams, engineering plastics, and epoxy resins.
• Use in flame-retardant treatments for textiles and fabrics.
• Potential application as a corrosion inhibitor in certain functional fluid formulations.
• Intermediate in organic synthesis for pharmaceutical and agrochemical research.

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 material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
