Ningbo Inno Pharmchem Co., Ltd. has developed a promising alternative to BASF Tinuvin 328, 2-(2-Hydroxy-3,5-di-pentylphenyl)benzotriazole, which has superior properties compared to its predecessor. This advanced UV absorber has a higher solubility and better compatibility with various polymer matrices, making it easier to use in different polymer applications.

2-(2-Hydroxy-3,5-di-pentylphenyl)benzotriazole, also known as Light Stabilizer UV-328, has a low volatility, excellent thermal stability, and outstanding absorption properties in both the UV-A and UV-B regions. Its broad absorption spectrum and high extinction coefficient make it an excellent UV absorber for use in outdoor applications, especially in polymers that are exposed to sunlight and weathering.

The chemical structure of 2-(2-Hydroxy-3,5-di-pentylphenyl)benzotriazole is 2-[2-Hydroxy-3,5-bis(1,1-dimethylpropylphenyl)]-2H-benzotriazole. It is also known as 2-(3,5-Di-tert-pentyl-2-hydroxyphenyl)benzotriazole, 2-(2-Hydroxy-3,5-di-tert-amylphenyl)benzotriazole, 2-(2H-benzotriazol-2-yl)-4,6-di-tert-pentylphenol, and 2-(2H-benzotriazol-2-yl)-4,6-bis(1,1-dimethylpropyl)-phenol. It is a white to light yellow crystalline powder that is soluble in organic solvents such as acetone, chloroform, and toluene.

2-(2-Hydroxy-3,5-di-pentylphenyl)benzotriazole is a versatile UV absorber that can be used in various polymer applications, including polyolefins, PVC, styrenics, engineering thermoplastics, and elastomers. It is particularly suitable for use in outdoor applications, such as automotive parts, building materials, and agricultural films, where polymers are exposed to sunlight and weathering.

Ningbo Inno Pharmchem Co., Ltd. is a reliable manufacturer of 2-(2-Hydroxy-3,5-di-pentylphenyl)benzotriazole.
