Multiwall Sun Polycarbonate Roofing Sheets

Sunlight board (English: sunlight, abbreviation: hollow Sheet), is a new type of high-strength, waterproof, light-transmitting and energy-saving roofing material, mainly made of PC raw materials. PC sunshine board is made of polycarbonate as the main raw material. Sunshine board quickly entered the building decoration industry in the mid-1980s.
There are also good and bad PC boards. At present, there are many PC boards (recycled boards) made of recycled PC monomers on the market. Compared with PC boards (new boards) made of pure new material PC, the performance difference is obvious.

Pure new material transparent PC board has excellent UV resistance, no yellowing for at least 5 years, no fading and loss of light, light transmittance greater than 91%, transparent and colorless at the section, excellent crack resistance and chemical resistance, high quality and protection The membrane provides adequate protection.

The recycled transparent PC board has very poor UV resistance. It will turn yellow at most half a year, the light transmittance is less than 86%, the cross section is yellow, easy to crack, and the quality of the protective film is poor.
