UV Absorber 234 is primarily designed to efficiently absorb ultraviolet radiation within the 290–400 nm wavelength range. Upon absorbing UV light, it ingeniously converts this photonic energy into harmless thermal energy, which is then dissipated, thereby preventing UV-induced degradation of polymer materials. Compared to conventional benzotriazole-based products, UV Absorber 234 features a deeply optimized molecular structure that results in exceptionally low volatility. This low volatility ensures that the product remains highly stable even in processing environments exceeding 150°C—such as injection molding, extrusion, and blow molding—significantly minimizing thermal loss during the manufacturing process.

Function

In automotive component manufacturing—specifically for parts requiring high-temperature molding, such as lamp covers and interior trim—UV Absorber 234 plays a pivotal role. It effectively blocks ultraviolet radiation, preventing lamp covers from aging or yellowing in a way that would compromise lighting performance, while simultaneously preserving the color and texture of interior trim to enhance the vehicle’s overall aesthetics and comfort.

The housings of electronic and electrical appliances are prone to discoloration and embrittlement resulting from prolonged exposure to ultraviolet light. The incorporation of UV Absorber 234 significantly bolsters the housing’s resistance to UV radiation, thereby extending the product’s service life and safeguarding internal electronic components against external environmental interference.

Photovoltaic backsheets are constantly exposed to the outdoors, where they endure intense ultraviolet radiation. UV Absorber 234 provides reliable protection for these backsheets, preventing material degradation, ensuring the stable operation of photovoltaic equipment, and enhancing power generation efficiency.

For thin-walled products or materials with a high specific surface area—such as films and fibers—conventional UV absorbers often suffer from high volatility, making it difficult to maintain an effective concentration. Thanks to its low volatility, UV Absorber 234 is able to maintain a high effective concentration within these material forms, ensuring uniform protection and enhancing product durability.

Architectural membranes and outdoor furniture coatings are constantly subjected to the rigors of wind and sunlight; UV Absorber 234 serves as a guardian for these materials, preventing aging and fading to preserve both the aesthetic appeal and functional integrity of buildings and furniture.
