Superior to other thermoplastics in chemical resistance, abrasion resistance and dielectric properties.

No other solid thermoplastic piping components can approach the combination of strength, chemical resistance and working temperature.  Impact strength 3 times that of PVC.  PVDF is non-toxic and imparts no odours or tastes to fluids.   The material can be extruded.  Gas permeability is extremely low.

Excellent chemical resistance to halogens such as chlorine and bromine, strong acids, such as hydrofluoric and nitric acids, organic solvents and oils.

PVDF is joined by the thermo-seal fusion process, threading or flanging.

General

• Gaskets
• Pipe liners

Sulphuric Acid Plants

• Liners for pipes and equipment
• Free sulphur trioxide (SO₃) will attack PVDF.  Therefore, 98% H₂SO₄ should be considered the absolute maximum concentration to be handled  by PVDF.  Other circumstances where free SO₃ may be present should be avoided.
