How long can the sunshade nets in the Linyi area maintain their performance after adding the anti-aging masterbatch?

The sunshade net is made of high-density polyethylene (HDPE) as the raw material. After being treated with ultraviolet stabilizers and anti-oxidation agents, it has the characteristics of strong tensile resistance, aging resistance, corrosion resistance, radiation resistance, lightness, etc. And the Lin yi area is relatively located in a high-latitude region, where the ultraviolet rays are relatively strong, which puts forward the highest requirements for the anti-aging master batch.
