PF-1 PVDF film be made by our company's patent(China patent no. 201110048732.4), it is the PVDF base nanocomposite, white color and opaque, with high mechanical strength, good thermal stability, low gas/liquids permeability, fire retardant, our PVDF film can effectively separate and absorb ultraviolet, completely sunlight degradation resistance, with excellent chemical resistance and outdoor weather durability.
PF type PVDF film mainly used as surface substrate material in the solar back sheet of coating composite technology.
