The durability of polycarbonate sunshades is mainly reflected in the following aspects:

Anti aging: polycarbonate has good weather resistance, and is not susceptible to aging caused by natural factors such as ultraviolet ray, temperature change, humidity, etc. Its molecular structure is stable, and it can maintain the stability of physical and mechanical properties when exposed to outdoor environments for a long time, reducing problems such as discoloration, brittleness, and cracking caused by aging, thereby extending its service life.

Impact resistance: Polycarbonate has high strength and excellent impact resistance, and can withstand large external impacts. As mentioned earlier, it is 300 times larger than ordinary glass and 20-30 times larger than acrylic sheet. Therefore, when facing harsh weather conditions such as hail and strong winds, polycarbonate sunshades are not easily broken or damaged, effectively protecting people and items below.

Wear resistance: Although the surface of polycarbonate is relatively soft, its wear resistance can be improved by adding special wear-resistant additives or surface hardening treatment. In daily use, it is not easy to show obvious wear marks due to frequent wiping, friction from wind blown gravel, etc., maintaining good appearance and transparency.

Waterproof and moisture-proof: Polycarbonate itself does not absorb water and has good waterproof performance. At the same time, sunshades are usually sealed during installation to effectively prevent rainwater infiltration and avoid long-term moisture affecting their performance and service life.

High temperature and low temperature resistance: Polycarbonate can maintain stable performance over a wide temperature range and can be used for a long time in temperature environments ranging from -40 ℃ to+120 ℃. Whether in the cold northern winter or the hot southern summer, it can function normally as a sunshade, protector, and will not deform or crack due to extreme temperature changes.
