our pc sheets have high impact strength (approximately 250 times that of glass and 3-5 times that of ordinary corrugated sheets) that makes them virtually unbreakable.
TRANSPARENCY AND LIGHT TRANSMISSION
excellent light transmission .its transparency is remarkably comparable to that of glass.
as sheet's surface have been treated with anti-UV ray agent to resist resin's fatigue caused by the sun, yellowing on sheets' surface would not occur. The protective UV coatelayer can maintain excellent light transmission of the sheets and prevent the sheets from becoming yellowing.10 years' quality warranty is provided.
compared with fiberglass (frp), pc sheets have remarkable characteristics of flame resistance and extinguishment to inflammability.
Heat and Cold Resistance no deterioration or deformation from-20 to 135 centigrade.
Installation and Processing
characteristic of light weight makes the sheets easy for transportation, handling and installation, with good processing performance in drilling, cutting and installing without having risks of breakage.
