2-[2-Hydroxy-3,5-bis(1,1-dimethylpropylphenyl)]-2H-benzotriazole: A Powerful UV Stabilizer for Plastics

Plastics are ubiquitous in modern society, used in everything from packaging to construction to electronics. However, exposure to ultraviolet (UV) radiation can cause significant degradation and discoloration of plastic materials over time, leading to reduced functionality and aesthetic appeal. To combat this problem, UV stabilizers are often added to plastic formulations to absorb and dissipate UV radiation, protecting the material from degradation. One highly effective UV stabilizer is 2-[2-Hydroxy-3,5-bis(1,1-dimethylpropylphenyl)]-2H-benzotriazole, also known as BASF light stabilizer Tinuvin 328 or simply UV-328.

UV-328 is a member of the benzotriazole family of UV stabilizers, which are widely used in the plastics industry due to their high efficiency, low volatility, and compatibility with a wide range of polymers. In particular, UV-328 has been shown to be highly effective in polyolefin and PVC applications, as well as in coatings and adhesives. Its excellent performance is due to its ability to absorb UV radiation in the range of 270-340 nm, which is the most damaging range for plastics. When irradiated, UV-328 undergoes a reversible photochemical reaction, dissipating the absorbed energy as heat and preventing it from reaching the polymer matrix.

UV-328 is produced by INNO SPECIALTY CHEMICALS, a leading manufacturer and supplier of specialty chemicals based in China. The company has established a reputation for quality and reliability, with a focus on research and development to meet the evolving needs of the global market. Their UV-328 product is available in both powder and granular form, making it easy to incorporate into a variety of plastic formulations.

One of the key advantages of UV-328 is its versatility in different polymer systems. It has been shown to be effective in polyolefins such as polyethylene and polypropylene, as well as in PVC, polystyrene, and acrylics. This makes it a valuable tool for formulators seeking to improve the UV stability of their products. Additionally, UV-328 is compatible with other stabilizers such as hindered amine light stabilizers (HALS), allowing for synergistic effects and enhanced performance.

In addition to its UV stabilizing properties, UV-328 has other benefits for plastic materials. It has been shown to improve thermal stability, reducing the likelihood of thermal degradation and extending the lifespan of the material. It also has a low color contribution, meaning it does not significantly affect the color of the final product. This is important for applications where color accuracy is critical, such as in automotive or consumer electronics.

Overall, UV-328 is a highly effective and versatile UV stabilizer for plastics, offering excellent protection against UV radiation and improving the durability and longevity of plastic materials. Its compatibility with a wide range of polymers and other stabilizers makes it a valuable tool for formulators seeking to improve the performance of their products. With its proven track record of quality and reliability, UV-328 from INNO SPECIALTY CHEMICALS is a trusted choice for UV stabilization in the plastics industry.
