For professionals in the chemical and manufacturing industries, a deep understanding of raw material properties, production processes, and reliable sourcing channels is crucial for success. Triphenyl Phosphate (TPP), a vital chemical compound, exemplifies this need. With its significant roles as both a flame retardant and a plasticizer, TPP demands careful consideration regarding its characteristics, how it's made, and where to procure it effectively. As a leading manufacturer and supplier of TPP in China, we aim to provide comprehensive insights into this essential material.

Triphenyl Phosphate (C18H15O4P, CAS: 115-86-6) is characterized by its appearance as a white flaky crystal. Key specifications often include a high assay (≥99%), low moisture content (≤0.1%), minimal free phenol (≤0.1%), and a low acid value (≤0.1 mgKOH/g). Its melting point typically falls within the range of 48-50°C, and it exhibits good thermal stability with a high flash point (around 435°F). TPP is insoluble in water but soluble in many organic solvents like benzene and chloroform, making it compatible with a wide array of industrial formulations. These properties collectively define its efficacy as a flame retardant and plasticizer.

The production of TPP generally involves two main methods: the direct thermal method using Phosphorus Oxychloride and the indirect cold method using Phosphorus Trichloride. In the thermal method, phenol is reacted with Phosphorus Oxychloride in the presence of a solvent and catalyst, followed by purification. The cold method involves reacting phenol and Phosphorus Trichloride to form triphenyl phosphite, which is then chlorinated and hydrolyzed to yield TPP. Both methods require precise control of reaction conditions, temperature, and purification steps to achieve the desired high purity. As a dedicated manufacturer, we employ advanced production technologies to ensure the consistent quality of our TPP.

For businesses looking to buy Triphenyl Phosphate, especially in bulk, sourcing from China offers significant advantages, particularly in terms of cost-effectiveness and scalability. Our company operates with a substantial annual output, ensuring that we can meet the demands of large-scale industrial operations. When inquiring about TPP price, it is important to consider the purity, production capacity, and reliability of the supplier. We pride ourselves on transparent pricing and a commitment to quality, making us a preferred Triphenyl Phosphate supplier for clients worldwide.

The applications of TPP are diverse, ranging from flame retardant plasticizer for cellulose resins, vinyl resins, natural rubber, and synthetic rubber, to its use in acetate films, rigid polyurethane foams, and engineering plastics like PPO. Its environmentally friendly, halogen-free nature makes it a preferred choice for industries aiming to comply with stricter regulations and environmental standards. Understanding these applications and the technical specifications of TPP is key for R&D scientists and formulators to optimize their product development.

In essence, a thorough understanding of Triphenyl Phosphate's properties and production is vital for its effective utilization. By partnering with a reputable China manufacturer like ourselves, you gain access to high-quality TPP, competitive pricing, and a reliable supply chain, ensuring your manufacturing processes are both efficient and sustainable.
