PVDF has outstanding barrier properties which allows a better protection of the environment. The construction of chemical process equipment makes use of a multitude of materials to cope with specific corrosion problems. PVDF has the advantage of absolute suppression of corrosion, even under varying process conditions, when compared to other materials.TECHNICAL INFORMATIONWhen compared with non-fluorinated thermoplastics, PVDF gives maximum reliance in chemical resistance, such as resistance to strong oxidising agents and concentrated mineral acids.
