Do plastic shading nets require anti-aging and anti-ultraviolet additives?

Shading nets are generally made of PE material, and their anti-aging effect is average. Therefore, anti-aging agents need to be added during the manufacturing process. Those shading nets advertised as being anti-ultraviolet and sun-resistant all contain anti-ultraviolet additives. Generally, products without added ultraviolet absorbers will fade within about one year. However, if ultraviolet absorbers are added, they usually won't fade for about 3 to 5 years. Ultraviolet absorbers have the functions of absorbing ultraviolet rays and have good thermal stability. 

From the above explanation, even those friends who are not familiar with artificial plants should understand now. All the plastic shading nets you have seen require anti-aging and anti-ultraviolet additives!
