In the demanding world of polymer science and manufacturing, ensuring the longevity and performance of plastic materials under various environmental conditions is paramount. Ultraviolet (UV) radiation is a primary culprit behind material degradation, leading to issues like discoloration, embrittlement, and loss of mechanical properties. This is where advanced additives, particularly Hindered Amine Light Stabilizers (HALS), play a crucial role. Among these, Bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate, commonly known as UV-770 or HALS 770, stands out for its effectiveness and versatility.

As a leading manufacturer and supplier based in China, NINGBO INNO PHARMCHEM CO.,LTD. specializes in providing high-quality functional material additives. Our Bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate (CAS 52829-07-9) is a low molecular weight HALS renowned for its ability to significantly enhance the UV stability of a broad spectrum of polymers. This makes it an indispensable component for product developers, procurement managers, and formulation scientists across various industries.

The efficacy of UV-770 stems from its unique chemical structure, which allows it to function as a radical scavenger. When polymers are exposed to UV light, free radicals are generated, initiating a chain reaction of degradation. UV-770 effectively intercepts these radicals, terminating the degradation process and thereby preserving the polymer's integrity and aesthetic appeal. This radical trapping mechanism provides a more durable and long-lasting protection compared to conventional UV absorbers, which can be depleted over time.

One of the significant advantages of our UV-770 is its excellent compatibility with a wide array of polymers. This includes polyolefins such as polypropylene (PP) and polyethylene (PE), styrenic polymers like polystyrene (PS) and ABS, as well as polyurethanes (PU) and polyamides (PA). Its low volatility and good migration resistance also ensure that it remains within the polymer matrix, providing consistent protection even under demanding processing conditions or prolonged use. For R&D scientists looking to buy UV-770 for their formulations, understanding this broad applicability is key to optimizing material performance.

Furthermore, UV-770 exhibits a synergistic effect when combined with other additives, particularly antioxidants. This dual action significantly boosts the material's overall resistance to degradation, offering enhanced thermal stability alongside UV protection. This makes it an ideal choice for applications requiring robust performance in challenging environments. When seeking a reliable supplier for such synergistic additive packages, considering manufacturers with a strong track record in China can provide a cost-effective solution without compromising on quality.

The recommended dosage for UV-770 typically ranges from 0.1% to 1.0%, depending on the specific polymer, the severity of UV exposure, and the desired level of protection. As a professional supplier, we are equipped to provide detailed technical guidance and support to help you determine the optimal concentration for your application. Whether you are looking to improve the outdoor durability of automotive components, extend the service life of construction materials, or maintain the clarity of packaging films, our UV-770 is a proven solution.
