How to make the aging life of the sun - shading net longer?

We all know that polyethylene plastic is a kind of polymer. During the production of polyethylene plastic, some catalysts are added to connect ethylene molecules together to polymerize and form ethylene plastic. It can be understood in this way that the polyethylene plastic we see is not actually a single piece, but is polymerized by many, many connected ethylene molecules. The role of the catalyst that polymerizes ethylene molecules is limited, and it will gradually lose its effectiveness in the process of maintaining the polymerization of ethylene molecules. During the use of polyethylene plastic products, environmental factors are often the main reasons for the failure of the catalyst and the aging of the plastic. Factors such as light and rain will cause the products to age. 

So, how to make the aging life of artificial plants longer? On the one hand, manufacturers should add anti - aging agents during production to delay the aging of products. On the other hand, attention should be paid to daily use and maintenance.
