Specification of crystal polycarbonate sheet:

crystal polycarbonate sheet application
1-Day lighting for building roofing/wall;
2-Decorating,advertising, Display Design;
3-Sound insulation wall for expressway, environment;
4-Roofing/wall for agricultrure greenhouse,garden, plant and cultivate;
5-Part of machine,electron, household electrical appliances equipment.

Polycarbonate solid sheet properties
Light transmission: Fine light transmitting rate approve to 30~ 85%.
Weather resistance: With anti-UV weather treatment on the surface, it can prevent the resin from fatigue and yellowing caused by UV. The anti-UV agent on the surface can change the UV absorbed by chemical bond into visible light, and finely stabilize the photosynthesis of plants.
Impact resistance: With the strength as 250 times of the ordinary glass,30 times as the PMMA sheet, it has less risk of breakage
Fire retardant: Fire retardency is up to B2 level(based on National GB8625-88 testing, without flame or toxic gas).
Temperature toleration: Without deformation within the temperature range from-40°C to +120°C.
Sound insulation: It is the best transparent materials for sound insulation engineerings as expressways,factories,etc..
Portability: Easy for handling and drilling,wo't be breakage whencutting, simple and easy be treated in using.

Notice When transporting, storing,installation:
· Keep PC panels away from wet cement surface or any alkaline/acid base materials.
· Keep frame clean and jointing groove flat and smooth.
· Use neutral glass cement and right gasket. Never use gasket of PVC material.
· Use electrical tools(tungsten carbide saw)to cut,stabilize PC panels to prevent their vibration.
· Choose right thickness of PC panels,allow flexure radius.
· Remain space for expanding,pay attention to inserting depth.
· In case that marks have to be made before cutting,try to mark on protective film;If the marks must be made directly on PC panels,use wax crayon instead of any sharp tool to mark.
· Never pill off protective films until installation is completed.
· Drilling and fixed:
If use self –drilling screws for fixing,the hole must be pre-drilled,the aperture should be 1,5 times larger than the diamenter of the screw,it is suggested to use roof hook for fixing.Do not tighten the screw strongly,otherwise stress will arise,and local crack on the sheet surface will appear.
· About purline span:
For the sheet 1.0mmthick,the span of purline is suggested to be less 1000mm.
For the sheet 1.2mmthick,the span of purline is suggested to be less 1200mm.
For the sheet 1.5mmthick,the span of purline is suggested to be  less  1500mm.
