Description

Guanidine Phosphate is an important inorganic salt of guanidine, widely recognized for its role as a high-efficiency flame retardant and a key intermediate in specialty chemical synthesis. Its value lies in its ability to impart significant fire resistance to materials while maintaining good thermal stability. This makes it a critical component for manufacturers in the polymer, textile, and construction material industries seeking to enhance product safety and meet stringent regulatory standards for flame retardancy.

Application

• Flame Retardant for Polymers & Plastics: A primary application is as an additive in engineering plastics, polyurethane foams, and epoxy resins to significantly improve fire resistance and meet safety regulations (e.g., UL 94).
• Textile Treatment Agent: Used in the formulation of durable flame-retardant finishes for fabrics, including those used in protective clothing, upholstery, and curtains.
• Wood & Paper Product Treatment: Acts as an effective fireproofing agent for wood composites, paperboard, and other cellulose-based materials.
• Chemical Synthesis Intermediate: Serves as a key building block in the production of more complex guanidine derivatives, pharmaceuticals, and specialty surfactants.
• Laboratory Reagent: Utilized in biochemical and pharmaceutical research as a protein denaturant and in buffer solutions.
• Adhesive & Coating Additive: Incorporated into certain adhesive and coating formulations to modify properties and enhance fire safety performance.

Quality Control

Our Guanidine Phosphate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and physical properties. Certificates of Analysis (COA) documenting key parameters such as assay, loss on drying, and heavy metal content are provided to guarantee consistent quality and traceability for our global B2B customers.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking and degradation.
