Tailor made technical and service solution
The technical knowledge and expertise at NEXA allows to develop close relationship with its customers, offering necessary support and valued consultancy.
More than 10 years’ experience in the perfluoroelastomer field are at NEXA customers’ disposal, even for projects involving small quantities but requiring special compounds developed for focused applications.
Performance with high temperature
NEXA Perfluoroelastomer products can resist temperatures up to 334 degrees C whilst at the same time maintaining their elasticity. They are widely recommended for use in water, steam and other wet applications. Tests performed after steam exposure for 168h @ 300 degrees C + dry-out 4h 120 degrees C, showed excellent steam resistance far higher than Triazine cured materials. The compression sets (test method in hot air) of NEXA compounds are considered the best values available for extreme applications, the bench mark for Perfluoroelastomer products.
Chemical Resistance
NEXA Perfluoroelastomer products have a wide spectrum of chemical resistance, withstanding aggression from numerous types of solvents, chemicals, plasmas and having a consistent low swell %.
Long Life
Thanks to their unique properties, NEXA seals present very low values of brittle deterioration and swelling, this being the key indication of premature failure in all types of seals static or dynamic. Due to this behaviour, NEXA products can ensure long life whilst at the same time reducing maintenance costs and risks of failure. The Seal performances have been enhanced so much, that in comparison to sealing elements lasting only 45 hours, NEXA products have continuously operated for more than 4300 hours in extreme conditions.
