How to identify the pros and cons of plastic UV absorbers

Plastic products are closely related to our daily lives, and their quality has also attracted much attention. Especially in outdoor use, the longer the durability, the more popular it is with customers. This requirement involves the issue of UV absorbers.

We all know that plastics are produced and processed from polymer materials, but they are often exposed to ultraviolet light outdoors, causing the molecular chain structure to be damaged, resulting in yellowing. , fading, brittleness and other appearance phenomena. In order to prolong the service life of their products, many manufacturers choose UV absorbers with different properties to protect their products as new for a long time.

There are many types of anti-aging additives on the market, with different performance characteristics and quality. If you want to choose a suitable UV absorber, you must have a clear understanding of the principles of many types of anti-aging additives. As the saying goes, “You can win every battle only if you know yourself and the enemy.” Ultraviolet absorbers belong to a category of anti-aging agents and are divided according to their chemical structures: salicylates, benzophenones, benzotrines, etc. Different types or models of UV absorbers have different absorption wavelengths and absorption peaks, and the absorption wavelength and absorption peak represent the anti-aging effect of the product.

If you choose different types and add different amounts, the effect will be completely different. Often in actual use, composite UV absorbers can improve the anti-aging level of products and slow down the aging rate in complex situations.

Currently, a well-matched UV absorber 284 meets the needs of customers. It has three-in-one effects of anti-oxidation, anti-ultraviolet, and light stability, protecting tens of millions of plastic product customers.
