covered 23 um dupont anti-aging film FRP lighting corrugated roofing sheet

Features of the product:
Light transmission
The light transmission of  covered 23 um dupont anti-aging film FRP lighting roofing sheet is  between 60-85%. Light through FRP roofing Sheet scatters and is mild. It will not form a light band so as to make the indoor brighter.
Weather resistance
The 23μm anti-aging film from Dupont covering on the surface of FRP roofing sheet improves its property of weather resistance. The anti- ultraviolet adsorbing agent mixing in the raw materials absorbs 99.9% of ultraviolet ray of the visible light transmitted through the FRP sheets.This UV protection will help to prevent the dissolution and discoloration of the materials. The unique technology used in FRP roofing Sheet  makes the life span of the sheet up to over 15 years, probably 20 years ( a ten-year warranty is supplied).
Impact resistance
The strengthening fiber-glass materials criss-cross the structure of the products,which  helps to improve the  impact resistance of FRP roofing sheet. When impacted by spalls or hails, they are hardly broken.
Corrosion resistance
The products resist various acids, alkalis and peroxides, especially suitable for  application in the coastal areas and corrosive places.
Temperature performance
FRP roofing Sheet is a kind of hot solid high polymer materials. It is designed for normal use in temperatures from - 40°C to120°C.
Temperature insulation
The coefficient of heat-conduction of  FRP roofing Sheet is 0.18kcat / mhr°C , only 1/4 of the glass. That is why it has a good property of temperature insulation.
Fire-retardant
Fire-retardant  the fire-retardant of FRP roofing Sheet is divided into ordinary gradeⅠ and gradeⅡ. The oxygen index of the gradeⅠof fire retardant is ≥32, the grade retardant is ≥26. It meets the standards of the fire brigade department.
Heat stability
  FRP roofing Sheet is a kind strengthening plastic of hot solid fiber-glass . Its coefficient of heat expansion is 2.2 x 10-5mm/mm/°C, only 2 times of metal materials. For this reason, when it matches with a metal sheet, the displacement is relatively small, not easy to leak.
