2,2,6,6-Tetramethyl-4-piperidine stearate: A Comprehensive Guide
2,2,6,6-Tetramethyl-4-piperidine stearate, also known as Solvay Light Stabilizer CYASORB UV-3808PP5, is a compound light stabilizer produced and supplied by INNO Specialty Chemicals from China. It is widely used in the plastics industry for its excellent UV absorption capacity, high thermal stability, and long-lasting performance.
UV radiation is a major cause of plastic degradation, leading to discoloration, cracking, and ultimately, failure of the material. To counteract this, various additives such as UV stabilizers, antioxidants, and light absorbers are incorporated into plastic formulations. Among these, 2,2,6,6-Tetramethyl-4-piperidine stearate is an effective UV absorber that can efficiently absorb UV radiation in the 290-400 nm region, which is the main cause of plastic degradation.
The chemical structure of 2,2,6,6-Tetramethyl-4-piperidine stearate consists of a hindered amine light stabilizer (HALS) group and an oligopolypropylene group. The HALS group acts as a free-radical scavenger, inhibiting the degradation of plastic caused by UV radiation. The oligopolypropylene group, on the other hand, provides compatibility and dispersibility in plastic formulations, ensuring that the additive is evenly distributed throughout the material.
2,2,6,6-Tetramethyl-4-piperidine stearate is suitable for use in a wide range of plastics, including polyolefins, PVC, ABS, and polyurethane. It is particularly useful in applications where long-term exposure to UV radiation is expected, such as outdoor furniture, automotive parts, and building materials.
One of the main advantages of 2,2,6,6-Tetramethyl-4-piperidine stearate is its thermal stability. It can withstand temperatures up to 300°C without significant degradation, making it suitable for use in high-temperature processing methods such as injection molding and extrusion.
Another advantage is its compatibility with other plastic additives. 2,2,6,6-Tetramethyl-4-piperidine stearate can be blended with other stabilizers, antioxidants, and processing aids to create customized formulations that meet specific performance requirements.
INNO Specialty Chemicals, the manufacturer and supplier of 2,2,6,6-Tetramethyl-4-piperidine stearate, is committed to delivering high-quality additives that meet the needs of the plastics industry. The company has a strong focus on research and development, continually improving its products to meet changing market demands.
In conclusion, 2,2,6,6-Tetramethyl-4-piperidine stearate is a highly effective UV stabilizer and light absorber that provides long-lasting protection against plastic degradation. Its thermal stability, compatibility with other additives, and versatility in a wide range of plastics make it a valuable component in plastic formulations. As the plastics industry continues to grow, the demand for high-quality additives such as 2,2,6,6-Tetramethyl-4-piperidine stearate is expected to increase, making it an essential component for manufacturers and processors alike.
