1. The membrane structure shed has weather resistance: there is a co extrusion layer with UV protection on the surface, which can prevent the resin from fatigue yellowing caused by solar UV. The surface coextruded layer has chemical absorption of ultraviolet light and conversion into visible light. It has a good stabilizing effect on plant photosynthesis (extremely suitable for protecting all kinds of cars, precious works of art and exhibits from UV damage).

2. Impact resistance: The impact strength of building film is 250-300 times that of ordinary glass, 20-30 times that of acrylic plate, and twice that of tempered glass. There is almost no risk of fracture, and it has the reputation of "unbreakable glass" and "sound steel".

3. Flame retardancy: according to the national GB8624-97 test, it belongs to Class B1 flame retardancy, without fire drops and toxic gas.

4. Temperature resistance: it will not cause deformation and other quality deterioration within the temperature range of - 40 ℃ to+120 ℃
