2-(2-Hydroxy-3,5-di-tert-butylphenyl)-5-chlorobenzotriazole: The Ultimate UV Stabilizer

UV radiation is a major concern for many industries, including plastics, coatings, and textiles. Exposure to UV rays can cause materials to degrade, fade, or discolor over time. To protect against these effects, manufacturers often incorporate UV stabilizers in their products. Among the many options available, 2-(2-Hydroxy-3,5-di-tert-butylphenyl)-5-chlorobenzotriazole, also known as UV-327, stands out as a highly effective and versatile UV stabilizer.

UV-327 is a member of the benzotriazole family, which is widely used in the production of plastics, coatings, and fibers. Its chemical structure includes a chlorinated benzotriazole ring and two tert-butylphenol groups, which provide excellent UV absorption and stability. UV-327 is a light yellow powder with a melting point of 145-150°C and a boiling point of 500°C. It is insoluble in water but soluble in many organic solvents, such as ethanol, acetone, and chloroform.

UV-327 is primarily used as a UV absorber and light stabilizer in plastics and coatings. It can effectively absorb UV radiation in the 290-400 nm range and convert it into harmless heat energy. This prevents the degradation of polymers and maintains the color and appearance of the finished product. UV-327 is particularly useful in applications that require high UV protection, such as outdoor furniture, automotive parts, and electronic devices.

UV-327 also has several advantages over other UV stabilizers. Its high thermal stability and low volatility make it suitable for use in high-temperature processes, such as injection molding and extrusion. It is also compatible with a wide range of polymers, including polyolefins, PVC, PET, and polycarbonate. UV-327 can be used alone or in combination with other UV stabilizers, such as hindered amine light stabilizers (HALS) and UV absorbers.

UV-327 is produced by INNO Specialty Chemicals, a leading manufacturer and supplier of specialty chemicals in China. INNO Specialty Chemicals has a strong focus on research and development, and has developed a wide range of UV stabilizers, antioxidants, and flame retardants for various industries. Its UV-327 product is of high quality and purity, and has been certified by many international standards, such as REACH, RoHS, and FDA.

In conclusion, UV-327 is an excellent choice for UV stabilization in many applications. Its unique chemical structure, high UV absorption, and versatility make it a preferred UV stabilizer for many manufacturers. With its superior performance and reliability, UV-327 is sure to continue to play a vital role in the protection of materials against UV radiation.
