Part 1 Introduction:
This pc hollow sheet extrusion line realizes continuous production of PC hollow grid sheet, which is applicable to construction decoration, advertisement collocation, and noise insulation of highway as well as packaging. It is characterized by light weight, high intensity,high transparency dampproof, and anticorrosion.
The technology of hollow sheet die with co-extrusion feed block to get UV+PC+UV, UV+PC hollow sheet can save 30% UV on the surface.

introduction
polycarbonate is best known for its very high impact resistance, fine optical clarity and excellen fire performance.hollow polycarboante is also often named as strutural polycarbonate, cellular polycarbonate, channel polycarbonate or multiwall polycarbonate.polycarbonate hollow sheets offer the higher level of glazing performance where transparency along with high impact strength is of vital importance. They have excellent physical, mechnical, electric as well as hot property which explains their high reputation in buildings and decoration industry. They are sold all over the world, making great contribution to customer's beautiful life.
UV protection
solar radiation has a harmful component by UV rays which initiate degradation of many polymetric material including polycarbonate.This depends on geographic locations, seasons etc. Polycarbonate sheets feature a specifically co-extruded UV absorption and protection layer, which provides long-lasting high stability against demanaging UV radiation, protects againts outdoor weathering and retains its original color and light transmission.
Material:
PC pellets (germany Baier brand )
UV material (germany Baier brand )
