Can window PE sun shades resist rain erosion?

The window PE sun shades can resist rainwater erosion to a certain extent, as shown below:
1. Good waterproof performance: PE (polyethylene) material itself has strong waterproof ability, which can effectively block rainwater infiltration and is not easy to absorb water. Therefore, when used on rainy days, sunshades will not absorb moisture and deform like fabrics.
2. Strong corrosion resistance: PE material has good corrosion resistance to most neutral or weakly acidic rainwater, and is not easily chemically degraded or corroded by long-term rainwater erosion. It is suitable for long-term use outdoors or near windows.
3. Easy to clean and dry: Due to its smooth surface, it is easy for rainwater to fall off and leaves little residue; Even if it is contaminated with dust or mud, cleaning is relatively convenient, the drying speed is fast, and it is not easy to breed mold.
4. Weather resistance and service life: Although PE has a certain degree of waterproofing, its material may gradually age, become brittle, and lose flexibility under long-term repeated exposure to sunlight, rain, especially the combined effects of ultraviolet radiation and acid rain. Therefore, regular inspection and replacement are necessary.
5. Suitable for short-term or moderate rainfall environment: PE sunshade performs well in ordinary rainy weather, but it may still be damaged due to mechanical stress or aging if it is exposed to extreme weather such as strong storm rain and hail for a long time.
