2,4-Di-tert-butylphenyl 3,5-di-tert-butyl-4-hydroxybenzoate: A Reliable UV Absorber for Polymer Applications

In the world of polymers, the role of UV absorbers is crucial to maintaining the material's stability and preventing degradation caused by UV radiation exposure. One such UV absorber that has gained popularity in recent years is 2,4-di-tert-butylphenyl 3,5-di-tert-butyl-4-hydroxybenzoate, also known as BASF Tinuvin 120 or UV-120. This article will explore the properties, benefits, and applications of this versatile UV absorber.

INNO SPECIALTY CHEMICALS from China is the manufacturer and supplier of this product. It is a white to off-white powder with a molecular weight of 530.8 g/mol. The chemical formula of this UV absorber is C30H44O3. It has a melting point of 141-144°C and a boiling point of 617.6°C at 760 mmHg. The solubility of this compound in water is low, but it is highly soluble in organic solvents.

One of the key properties of 2,4-di-tert-butylphenyl 3,5-di-tert-butyl-4-hydroxybenzoate is its excellent UV absorption properties. It has a high molar extinction coefficient, which means it can effectively absorb UV radiation in the range of 290-400 nm. This makes it an ideal candidate for use in a wide range of polymer applications, including plastics, coatings, adhesives, and fibers.

In addition to its UV absorption properties, this UV absorber also has excellent thermal stability. It can withstand high temperatures without degrading, making it ideal for use in applications where high-temperature processing is required, such as in the production of automotive parts or electronic devices.

2,4-di-tert-butylphenyl 3,5-di-tert-butyl-4-hydroxybenzoate also has good compatibility with a wide range of polymers, including polyolefins, polystyrenes, polyesters, and polyamides. It can be easily incorporated into these materials during the production process, providing long-lasting protection against UV radiation.

One of the main benefits of this UV absorber is its ability to improve the longevity and durability of polymer materials. UV radiation can cause polymer materials to degrade over time, leading to discoloration, cracking, and brittleness. By incorporating 2,4-di-tert-butylphenyl 3,5-di-tert-butyl-4-hydroxybenzoate into polymer materials, manufacturers can extend the lifespan of their products and ensure they remain in good condition for longer.

Another benefit of this UV absorber is its low volatility. It does not easily evaporate from polymer materials, even at high temperatures, which means it can provide long-lasting protection against UV radiation.

2,4-di-tert-butylphenyl 3,5-di-tert-butyl-4-hydroxybenzoate has a wide range of applications in the polymer industry. It is commonly used in the production of automotive parts, such as bumpers and dashboards, as well as in the production of electronic devices, such as computer cases and cell phone housings. It is also used in the production of outdoor furniture, sports equipment, and other products that are exposed to UV radiation.

In conclusion, 2,4-di-tert-butylphenyl 3,5-di-tert-butyl-4-hydroxybenzoate is a reliable UV absorber that provides excellent UV protection, thermal stability, and compatibility with a wide range of polymers. Its ability to improve the longevity and durability of polymer materials makes it a valuable addition to the polymer industry. With its low volatility and versatility, it is an ideal choice for manufacturers looking to protect their products against the harmful effects of UV radiation.
