Corrugated Polycarbonatesheet 1. Light transmission: up to 85%--89% 2. Weather resistance: it has 50 micron UV protective layer. It can prevent the sheet from harmful ultraviolet ray and absorb more than 99% ultraviolet ray to provide a stable effect on the photosynthesis of plants 3. Impact resistance: it is hardly broken, its impact strength is 10 times of the ordinary and 2 times if toughened glass. 4. Temperature property: In the temperature from -40∼+120,the product will not deform 5. Light weight: it is light, easy to handle and drill, convenient for construction and procession. The density is 1.2g/cm3 Notes: 1. Never contact the surfaces of wet cement, acid or alkali materials 2. Never contact the organic solution or glue and paint consisting of the organic solution
