Light Stabilizer 622 (LS 622) is a highly effective UV stabilizer, available as a white to slightly yellowish powder. With high purity and fineness, this additive is readily soluble in common organic solvents. Its molecular structure enables it to absorb UV radiation and convert it into harmless heat energy. As a result, it protects plastics and other materials from the harmful effects of UV radiation, such as color changes, embrittlement, and degradation of mechanical properties.

Applications of Light Stabilizer 622

In the plastic industry, LS 622 is commonly used as an additive in various polymers, including polyethylene, polypropylene, PVC, and polyurethane. By adding this stabilizer, plastic products remain colorfast for longer periods and retain their mechanical strength even under prolonged sunlight exposure. This makes them ideal for outdoor use, such as in garden furniture, plastic claddings, and profiles

In the construction industry, LS 622 is employed in a variety of building products, including roofing materials, facade claddings, window profiles, and pipes. By adding this stabilizer, materials remain stable and resistant to UV radiation even under extreme weather conditions, extending their lifespan and reducing maintenance costs.

In the automotive industry, LS 622 is often used in plastic components installed in the vehicle interior or on the body. This stabilization technology protects plastics from fading and embrittlement due to sunlight exposure, preserving the appearance of the vehicle and extending the lifespan of the components.

In the packaging industry, LS 622 is employed to enhance the durability and attractiveness of plastic packaging. By adding this stabilizer, packaging remains colorfast and resistant to UV radiation for longer periods, protecting the quality of the packaged products and increasing their shelf life.

Light Stabilizer 622 is an indispensable additive for the long-term stabilization of materials, particularly in industries exposed to intense sunlight. Its ability to absorb UV radiation and protect materials from harmful effects makes it a crucial component of many products requiring longevity and quality.
