In recent years, polycarbonate roofing panels have been widely used due to their long service life, good thermal insulation performance, high impact resistance and reasonable price. As a result, there are many inferior polycarbonate panels, which confuse people's choice. Let's take a look at how to choose the polycarbonate roofing sheets.
1. Watch burning. Select a piece of PC solid sheet for combustion test, and a good quality PC solid sheet will extinguish itself after it is far away from the fire source.
2. Look at the light transmittance of the sheet. The PC solid sheet produced by imported new materials such as Lexan Makrolon has the best light transmittance, no points on the surface, and no impurities and pits inside the sheet. Several samples of PC solid sheets can also be placed on a white On the paper, the PC solid sheet produced from recycled materials is dark and has pitting on the surface, while the imported new material produced has good light transmittance, is transparent and shiny, and has no pitting on the surface.
3. The anti-fog layer of the UV layer is a key factor that causes the aging of the panels. Therefore, more and more manufacturers are now choosing to co-extruded UV protection layers. the UV layer of a good quality polycarbonate panel cannot be measured only by the thickness, but also to see the uniformity of its co-extrusion. It is necessary to choose a PC roofing sheet with a good UV layer thickness and uniformity. The identification of anti-fog polycarbonate is actually very simple. Take a cup of hot water and put it under the panel. If the condensed water forms fog or water droplets on the lower surface of the panel, it means that the anti-fog effect is not good.
4. The installation and construction are not been neglected. Choosing a good-quality polycarbonate is only the first critical step. Installation is a more critical step. Edge sealing and punching are the key factors that determine the quality of the polycarbonate roofing installation technology. If it is not installed well during the installation process, then It will damage the service life of the polycarbonate panel, so the installation process must not be taken lightly.
I hope that you will not be misled in the process of purchasing polycarbonate sheets. As a professional polycarbonate manufacturer, UNIQUE always uses 100% new raw material to ensure high quality.
