"PE material" usually refers to polyethylene (Polyethylene) material, which is widely used in the manufacture of tarpaulins. Polyethylene has certain weather resistance and UV resistance, but the specific resistance to sunlight depends on factors such as the type of material, density, additives, and manufacturing process.

In general, high-density polyethylene (HDPE) has better weather resistance and UV resistance than low-density polyethylene (LDPE). When making tarpaulins, additives such as antioxidants and UV absorbers are usually added to improve the durability and UV resistance of the material.

If you are considering buying or using a PE material tarpaulin, it is recommended that you check the product description before purchasing to understand the material specifications and performance. Also, you can refer to other users' reviews and experiences to get more information on how the tarpaulin performed in actual use.
