Hexaphenoxycyclotriphosphazene (HPCTP) is a flame retardant compound that has been developed to improve the fire safety of various materials. It is a white powder with the chemical formula (C6H5O)6P3N3 and is also known as phenoxycyclophosphazene.
HPCTP has excellent thermal stability, high char yield, and low toxic gas emissions during combustion. It can be used as a flame retardant in many applications, including plastics, textiles, and coatings. It has been widely used in electronic devices, construction materials, and transportation industries.
Ningbo Inno Pharmchem Co., Ltd., a leading chemical manufacturer and supplier in China, produces high-quality HPCTP. The company has a state-of-the-art production facility and a team of experienced professionals who ensure that the product meets the highest quality standards.
Manufacturing Process
The manufacturing process for HPCTP involves several steps, including the reaction between hexachlorocyclotriphosphazene and phenol. The reaction is carried out in the presence of a catalyst, such as sodium carbonate.
The resulting product is then purified to remove any impurities and ensure that the final product meets the required specifications. Ningbo Inno Pharmchem Co., Ltd. has developed a proprietary purification process that ensures the highest purity and quality of HPCTP.
Chemical Properties
HPCTP has a molecular weight of 1059.8 g/mol and a melting point of 238-240°C. It is insoluble in water and most organic solvents, but can be dissolved in some polar solvents, such as dimethylformamide and N-methylpyrrolidone.
HPCTP has a high phosphorus content, which contributes to its flame retardant properties. When exposed to high temperatures, it decomposes to form a protective char layer that prevents the material from burning.
Applications
HPCTP is widely used as a flame retardant in various applications, including plastics, textiles, and coatings. It has been shown to significantly improve the fire safety of these materials without compromising their mechanical properties.
In the electronics industry, HPCTP is used as a flame retardant in printed circuit boards, cables, and connectors. It has also been used in the production of mobile phones, laptops, and other electronic devices.
In the construction industry, HPCTP is used to improve the fire safety of building materials, such as insulation, roofing, and flooring. It can also be used in the production of transportation materials, such as aircraft interiors and automotive parts.
Conclusion
Hexaphenoxycyclotriphosphazene is a highly effective flame retardant that has been widely used in various industries to improve the fire safety of materials. Ningbo Inno Pharmchem Co., Ltd. is a leading manufacturer and supplier of high-quality HPCTP.
The company has a state-of-the-art production facility and a team of experienced professionals who ensure that the product meets the highest quality standards.
