Polymers are ubiquitous in modern manufacturing, but their susceptibility to degradation from UV radiation presents a significant challenge. UV exposure initiates photochemical reactions that break down polymer chains, leading to embrittlement, discoloration, and loss of mechanical properties. To combat this, UV stabilizers are essential additives, and among the most effective are Hindered Amine Light Stabilizers (HALS). UV Stabilizer 123, identified by CAS number 129757-67-1, is a prominent example of a highly efficient HALS widely used in polymer stabilization.

UV Stabilizer 123 is characterized by its liquid form and low alkalinity, which are key attributes contributing to its versatility and performance. Its low basicity makes it particularly advantageous for applications where acidic components are present, such as in certain coating formulations or polymer systems. This characteristic prevents unwanted interactions that could neutralize the stabilizer's effectiveness or interfere with other additives.

The primary function of UV Stabilizer 123 is to protect polymers from degradation caused by UV light and thermal oxidation. It achieves this by acting as a radical scavenger. When UV radiation interacts with a polymer, it can generate highly reactive free radicals. HALS molecules intercept these radicals, preventing them from initiating chain reactions that lead to material breakdown. This regenerative mechanism allows HALS to offer long-term protection even at low concentrations.

As a leading supplier of polymer additives in China, we offer UV Stabilizer 123 for a wide range of applications. It is commonly used in plastics such as polypropylene (PP), high-density polyethylene (HDPE), polystyrene (PS), and acrylonitrile butadiene styrene (ABS) resins. Its incorporation enhances the weatherability and service life of these polymers, making them suitable for outdoor applications or products exposed to sunlight. For instance, when you buy UV stabilizer for PP, this HALS can significantly improve its resistance to yellowing and brittleness.

Beyond plastics, UV Stabilizer 123 is highly valued in the coatings industry. Its compatibility with various resin systems, including acrylics and polyurethanes, makes it an excellent choice for automotive finishes, industrial coatings, and wood coatings. By preventing gloss reduction, cracking, and chalking, it helps maintain the aesthetic and protective functions of these coatings. Companies looking to purchase polymer stabilizers for enhanced product performance will find this HALS to be a valuable addition to their formulations.
