Fluorine Film Laminating Fabric
PVDF-FL (Fluorine Film Laminated Fabric) Weldable!
Newly developed product, PVDF-FL series have a high quality thicker fluorine layer onto the PVC coated fabric.
It provides durable protection to maintain an attractive appearance.
PVDF-FL series are suitable fabrics for structures that require a high quality appearance.
Difference of PVDF-FL and PVDF coating
PVDF-FL has a high quality fluorine top layer which is more than 5 times thicker than PVDF-coating.
This top layer brings superior dirt resistance and durability of surface.
PVDF-FL is a suitable product for projects that require superior long-term dirt resistance, and is a well-balanced product than laminating fabric.

PVDF-FL - Proven dirt resistance
A below picture shows that the outer appearance of a 15-year-old warehouse had been clean condition.
Dirt adhered initially had been disappearing year by year.
The dirt resistance of PVDF-FL fabric has been proven successful for our warehouse.
PVDF-FL - Durability of surface
