Zestha Polycarbonate Hollow Sheet is a new type of construction material with high strength, heat insulation, and good light-transmission. This product is a unique engineering thermo plastic, which combines a high level of physical, mechanical, electrical, and thermal properties. Therefore, it has a beautiful name as the 'King of the Engineering Plastic'. Thanks to their excellent advantages of high impact resistance, good heat insulation, sound insulation, light weight, flame resistance, anti-ultraviolet radiation and good machining capability and strong randomness. The Polycarbonate Hollow Sheets are widely used in public and private construction and applicable for industrial roofs and sidewalls, sunroom, swimming pool and conservatory rooting, shopping centre roofing, railway station, football stadium roofing, sound insulation board, agricultural greenhouse and display of advertisement, etc. Polycarbonate Hollow Sheet is an optical canopy material in the world at present and widely canonized and in favor of modern construction and decoration group.
Advantages and Features :

• Light – Transmission : Excellent light transmission. The light-transmission rate is from 12“to82% depending upon thickness
• Impact Resistant : Impact-resistance of` PC hollow sheets is 80 times of glass. When the dart of weight 2kg falls from height of lm the sheet surface shows no cracks
• Light Weight : Weight of PC hollow sheet is only l/l2 of that of glass in the same thickness
• D. Weather Resistant : Super weather resistance. All physical characteristics keep stable at —40^oC - l2D^oC
• Ultraviolet Resistance : The surface of PC hollow sheet is extruded with anti-UV layer that keeps the sheet from wearing out, fading and can lengthens the service time to more than l0 years
• Flame Resistance : PC hollow sheet has fine flame-resistance rated class Bl and can only ignite itself an 630^oC. The fire will not spread and will extinguish automatically when keep away from fire

• During transportation and store. Please do not put sheets under sunshine or the places where can be drenched. Do not place PC sheets on the cement floor or against cement wall directly
• Before installation, do not damage or tear protective films
• While cutting, do not tear protective films, and seal both ends of the sheet with dust proof sticky tape in time
• In order to allow the displacement caused by sheet's thermal expansion, the hole's diameter should be 20% greater than that of screw
• Before installation, uncover about 5cm protective films of the sheet's four sides
• While needing cold bending, the bending direction cannot be perpendicular to the sheet's ribs, otherwise some fracture will be caused. The cold bending radius of PC hollow sheet must be 175 times of` sheet's thickness
• While installing the sheet, enough flexible space must be reserved according to local temperature difference
• After finishing installation, protective films cannot exceed one day under sunshine and rain, so please tear the protective films in time
• Please choose suitable silicon gel and liner materials, do not use such materials as PVC
• It the sheet is dirtied by caulk, oil, etc., be sure to clean it with Soti cloth and alcohol before hardening
• Do not wash the sheet with such chemical solvents as benzene, petrol, carbon of Tetra chloride, etc.
• To the dust and dirt on sheet's surface, please wipe with Soti cloth or sponge dipped with neutral sanitizer at first, then wash with warm water completely and finally dry with soft cloth
