OMNISTAB® LS3346 – High-performance, long-lasting light stabilization for superior weatherability.

Polymer materials are being used in an increasingly wide range of applications, making weatherability one of the key indicators of material quality. As a critical additive for improving the weatherability of polymer materials, the performance of light stabilizers has a direct impact on the service life and long-term stability of the material. Among the various types of light stabilizers, Hindered Amine Light Stabilizers (HALS) are recognized for their outstanding light stabilization efficiency and have become one of the most widely used classes. However, conventional low-molecular-weight HALS are prone to migration, volatilization, and extraction, making them unable to meet the requirements of high-temperature processing conditions and applications demanding superior weather resistance.

    OMNISTAB® LS3346 is a high-molecular-weight Hindered Amine Light Stabilizer (HALS) that delivers highly efficient light stabilization. It effectively overcomes the limitations of conventional low-molecular-weight HALS, providing long-lasting and reliable light stabilization for a wide range of polymeric materials.

1.Precise Control of Molecular Weight

OMNISTAB® LS3346 has a relative molecular weight ranging from 1,500 to 3,000 g/mol, achieving an ideal balance between migration resistance and light stabilization performance. It effectively reduces volatilization, migration, and extraction loss while avoiding the poor dispersion and limited replenishment capability typically associated with products of excessively high molecular weight.

2.Bifunctional group

The combination of hindered amine and triazine functional groups provides excellent thermal stability, low plate-out, and minimal weight loss, ensuring reliable performance even under demanding processing conditions.

3. Excellent Processing Performance

OMNISTAB® LS3346 features low color contamination, low volatility, and uniform, well-rounded granules. These characteristics facilitate storage, transportation, and incorporation during processing, while ensuring excellent dispersion throughout the polymer matrix.

LS3346 is particularly suitable for weather-resistant polyolefin applications, including films, raffia tapes, fibers, sheets, and injection-molded products, providing long-lasting and reliable protection against UV-induced degradation in outdoor applications.
