What is the protection mechanism of the compound anti-aging masterbatch? Are there any disadvantages?

 protection mechanism of ultraviolet absorbers is to absorb harmful ultraviolet radiation (light within 400nm is ultraviolet light) and dissipate the energy as heat. The absorption peaks of different ultraviolet absorbers are different. 

A major drawback of ultraviolet absorbers is that a certain absorption depth (product thickness) is required for them to play a protective role. Therefore, for thin filaments, films, etc., it is not advisable to use this kind of additive. 

In response to this, the experts from Hangzhou Hefu have carefully selected a variety of materials to compound an anti-aging masterbatch, which has effectively solved this problem. It can not only be used for sunshade nets but also address the aging problem of greenhouse films.
