In the competitive world of polymer manufacturing, ensuring the longevity and performance of plastic products is paramount. One of the primary culprits behind material degradation is exposure to ultraviolet (UV) radiation, which can lead to discoloration, embrittlement, and loss of mechanical strength. This is where UV absorbers, such as our high-efficiency UV Absorber 326, play a critical role. As a premier manufacturer and supplier based in China, we understand the challenges faced by product formulators and are dedicated to providing solutions that enhance product durability and marketability. If you are looking to buy UV absorber 326 for your plastic applications, understanding its benefits is key.

UV Absorber 326, chemically known as 2-(2'-hydroxy-3'-t-butyl-5'-methylphenyl)-5-chlorobenzotriazole (CAS No. 3896-11-5), is a highly effective light stabilizer from the hydroxyphenylbenzotriazole class. Its primary function is to absorb harmful UV radiation, particularly in the 300-400nm wavelength range, and dissipate it as harmless thermal energy. This absorption mechanism prevents the UV light from initiating degradation processes within the polymer matrix.

One of the standout features of UV Absorber 326 is its excellent compatibility with a wide array of polymers, including polyolefins (like polyethylene and polypropylene), polyvinyl chloride (PVC), polycarbonate, and notably, cold-cured polyesters. Its effectiveness in these materials makes it a go-to choice for applications requiring extended outdoor exposure. For instance, using UV Absorber 326 in automotive parts, outdoor furniture, or agricultural films significantly extends their service life and maintains their aesthetic appeal. When considering the price and performance, purchasing from a reliable manufacturer ensures you receive a product that meets stringent quality standards.

Furthermore, UV Absorber 326 boasts low volatility and high resistance to thermal degradation. This means it can withstand the high temperatures often encountered during plastic processing, such as extrusion and injection molding, without significant loss or decomposition. This attribute is vital for manufacturers who rely on consistent additive performance throughout their production cycles. As a dedicated supplier, we ensure that our UV absorber 326 is readily available to meet your production schedules.

The recommended addition levels for UV Absorber 326 typically range from 0.1% to 0.5%, depending on the specific polymer, application, and desired level of protection. This efficient usage further contributes to its cost-effectiveness. For businesses seeking to improve their product's resilience against UV damage and reduce warranty claims or product failures, investing in high-quality UV Absorber 326 from a trusted manufacturer is a strategic decision. It's not just about buying a chemical; it's about securing a vital component that guarantees long-term product integrity.
