Ningbo Inno Pharmchem Co., Ltd is a leading manufacturer of specialty chemicals, and they have recently introduced a new product into their portfolio that has been making waves in the industry. Their 2-(2-Hydroxy-5-tert-octylphenyl)benzotriazole, which is also known as UV-329, is a highly effective light stabilizer that offers a range of benefits to numerous applications.

What is 2-(2-Hydroxy-5-tert-octylphenyl)benzotriazole?

2-(2-Hydroxy-5-tert-octylphenyl)benzotriazole, or UV-329, is a highly effective ultraviolet absorber that is used to protect polymers and plastics from UV radiation. It is a white or light yellow powder with a molecular weight of 323.4 g/mol and a melting point of 102-105°C. It is soluble in organic solvents and shows good compatibility with most polymers.

What are the benefits of using UV-329?

UV-329 offers a range of benefits that make it an excellent choice for use in various applications. Firstly, it provides excellent UV stability to polymers, which helps to prevent color fading, embrittlement, and other forms of degradation caused by UV radiation. This makes it an ideal choice for use in outdoor applications such as automotive parts, building materials, and agricultural films.

Secondly, UV-329 is highly effective at absorbing UV light in the range of 270-380 nm, which is the range most harmful to polymers. This means that it offers superior protection compared to other UV absorbers that may only be effective in a narrower range of wavelengths.

Finally, UV-329 is highly stable and does not degrade or migrate over time, which means that it provides long-lasting protection to polymers and plastics.

How does UV-329 compare to other UV absorbers?

There are several other UV absorbers on the market, such as BASF light stabilizer Tinuvin 329, BASF Tinuvin 329, Cytec Light Stabilizer CYASORB UV-5411, American Cytec UV-5411, and Cyasorb UV-5411. However, UV-329 offers several advantages over these products.

Firstly, UV-329 is more effective at absorbing UV light in the range of 270-380 nm, which is the most damaging range to polymers. This means that it offers superior protection compared to other UV absorbers that may only be effective in a narrower range of wavelengths.

Secondly, UV-329 is highly stable and does not degrade or migrate over time, which means that it provides long-lasting protection to polymers and plastics. Other UV absorbers may degrade or migrate over time, which can reduce their effectiveness.

Finally, UV-329 is more cost-effective than other UV absorbers, which makes it an ideal choice for applications where cost is a factor.

Is UV-329 safe to use?

UV-329 has been extensively tested for safety and has been found to be safe for use in a wide range of applications. It is not classified as hazardous according to the European Union's Classification, Labelling, and Packaging (CLP) regulation, and it does not pose any significant risks to human health or the environment when used as intended.

In conclusion, Ningbo Inno Pharmchem Co., Ltd is a leading manufacturer and supplier of 2-(2-Hydroxy-5-tert-octylphenyl)benzotriazole, or UV-329, which is a highly effective ultraviolet absorber that offers a range of benefits to numerous applications. It provides excellent UV stability to polymers, is highly effective at absorbing UV light in the range of 270-380 nm, and is highly stable and does not degrade or migrate over time. It is also safe for use in a wide range of applications, making it an ideal choice for a variety of industries.
