① Light transmission: good light transmission performance (Hengli Electric this electric canopy roof light transmission rate of 88%). Exposure to the sun will not produce yellowing, fogging, poor light transmission.
② Weather resistance: the surface has a co-extruded layer of UV protection, which can prevent the fatigue of resin yellowing caused by the sun's UV rays. The surface co-extruded layer can chemically absorb UV light and convert it into visible light. It has a good stabilizing effect on plant photosynthesis.
③ Impact resistance: the impact strength of polycarbonate sheet is 250-300 times that of ordinary glass, twice that of tempered glass, almost without the risk of fracture, with the reputation of "unbreakable glass" and "ringing steel".
④Temperature resistance: It will not cause deformation and other quality deterioration in the temperature range of -40℃ to +120℃.
⑤ Sound insulation: good sound insulation effect.
