OMNISTAB® UV3529 – Builds a Solid Barrier to Guard Polyolefins from Photoaging

Hindered amine light stabilizers (HALS) are a core additive in the protection of polymer materials, offering outstanding inhibition of photo-oxidative degradation. They are widely used in plastics, synthetic fibers, coatings, and a variety of other applications, serving as an essential protective component that ensures long-term stability of materials.

However, traditional low-molecular-weight HALS are gradually falling short of the increasingly demanding requirements in real-world applications. This has driven a significant trend toward high-molecular-weight HALS, which offer clear advantages: substantially lower volatility and reduced migration, allowing them to remain within the material for extended periods and provide lasting protection. They also exhibit better compatibility with polymers and various additives, broadening their range of applicability. In addition, their improved resistance to discoloration and gas fading helps maintain both the appearance and performance stability of materials, laying a solid foundation for the development and application of high-end materials. 

OMNISTAB® UV3529 is a high‑molecular‑weight light stabilizer that incorporates both triazine and hindered amine groups in its structure. It offers excellent high‑temperature resistance, resistance to extraction, and high light‑stabilizing efficiency, delivering a comprehensive upgrade in protection performance.

OMNISTAB® UV3529 offers the following core advantages

As a polymeric high-molecular-weight HALS additive, it provides long-lasting UV and thermal protection for polyolefin materials, significantly extending their service life.

With its low-basicity HALS chemistry, it exhibits excellent acid resistance.

It features low color contribution, with minimal impact on material color, making it suitable for light-colored or transparent products. It also offers outstanding resistance to discoloration and gas fading, meeting the high aesthetic standards required for premium applications.

Thanks to its extremely low volatility, it can be widely used in various polyolefin products, including fibers, tapes, films, sheets, pipes, and molded parts, effectively enhancing the long‑term performance of polyolefin materials.
