The relentless exposure to ultraviolet (UV) radiation from sunlight poses a significant threat to the integrity and appearance of polymer-based products. Over time, UV exposure can initiate complex chemical reactions within the polymer matrix, leading to a cascade of detrimental effects. This process, known as photodegradation, manifests as fading colors, chalking surfaces, cracking, and a loss of crucial mechanical properties such as tensile strength and flexibility.

To combat these effects and significantly extend the useful life of polymers, the incorporation of UV absorbers is indispensable. These additives function by preferentially absorbing harmful UV radiation and dissipating the energy harmlessly, typically as heat. Among the various classes of UV absorbers available, triazine derivatives have emerged as highly effective solutions, particularly for demanding applications.

A standout example in this category is the UV absorber identified by CAS number 1820-28-6. This chemical is specifically engineered to offer robust protection against UV-induced damage. Its molecular structure is optimized to efficiently absorb a broad spectrum of UV light, thereby shielding the polymer from the most damaging wavelengths. What sets this particular UV absorber apart, according to industry professionals and chemical suppliers, are its superior performance characteristics. These include a notably low volatility, meaning it remains within the polymer during high-temperature processing and throughout the product's service life. Furthermore, its excellent extraction resistance ensures that the protective agent is not leached out when the product encounters solvents or cleaning agents.

This makes the triazine UV absorber with CAS 1820-28-6 an ideal additive for a wide array of polymers, including Polypropylene (PP), Polyethylene (PE), Polycarbonate (PC), Polystyrene (PS), ABS resins, PVC, Nylon, and Polyurethane (PU). Its inclusion can dramatically improve the weatherability of plastic components used in automotive exteriors, construction materials, agricultural films, and outdoor furniture. Moreover, a key aesthetic advantage is its light yellow appearance, which generally does not impart undesirable color or affect the transparency of the base polymer, preserving the product’s intended look and feel.
