upvc roof tiles vs pvc roof tiles
The difference between UPVC roof tiles and PVC roof tiles lies in the material, performance and production method.
1. Materials
UPVC roof tile is made of polyvinyl chloride (PVC) as the basic raw material or additive, adding silicone (CAS), sulfophenol (BPO) copolymer, anti-ultraviolet synergist and stable preservative, and mixed by mechanical stirring After foaming and molding pressure treatment, in order to achieve the good effect of anti-ultraviolet and anti-mold.

PVC roof tiles are made of polyvinyl chloride (PVC) as the base material, added with stabilized preservatives, stirred and mixed, and then extruded to form roof panels.
2. Performance
UPVC roof tiles have good air tightness, corrosion resistance and UV resistance, and can significantly reduce water leakage and ensure the smoothness of the roof surface.
PVC roof tile has the characteristics of anti-oxidation, aging resistance, good weather resistance, good water resistance, high temperature resistance, small size and light weight.
3. Production method
UPVC roof tiles are usually made by extrusion/injection molding/compression molding processes, which have the advantages of simplicity and novelty, rich variety, beautiful shape, rich color, fine texture, stable performance, energy saving and environmental protection, etc.
The PVC roof tile is injection molded, with moderate hardness and smooth surface.
