What is Polycarbonate Sheet?
Polycarbonate Sheet (PC Sheet) is a high polymer with excellent impact resistance, transparency and light transmission. The PC sheets are widely used in factories, buildings(corridors and windows, etc.), rain-shields, garages, greenhouses and orchid gardens, and etc.

By using UV-absorbing agent (benzotriazoles), the plastic products has been stabilized so as not to become yellowish, particularly in the range of UV wavelength of 290nm-400nm. Thus the PC sheet always remains fresh and is capable of screening off the UV ray within 400nm harmful to human health. Records have proved that almost 99.5% of UV ray can be blocked.
LIHYANG UV PC corrugated sheets are the UV-proof products utilizing high density 12% UV-absorbing agent in thickness of 0.04mm which is evenly coated on the surface of the sheets via co-extrusion process.
With less than 2.4% UV-ray penetrability within wave length 300nm, LIHYANG PC sheets shall not become yellowish and whitening and are virtually unbreakable. For long-term consideration, LIHYANG UV PC Weather-Proof corrugated sheets, which meet international CNS quality standard, are your best choice. While in installing, the UV-coated sides of the sheets printed with "UV-Proof" should face the sun.
