Outstanding chemical resistance at elevated temperatures
- Virtually inert to most organics, acids and bases
- Usable up to 260°C / 500°F and tougher than PTFE
- Excellent electrical insulator
- High purity for sensitive pharmaceutical and food type applications
- PFA material datasheet
PFA nuts made from perfluoroalkoxy alkanes (PFAs) are fluoropolymers with properties similar to polytetrafluoroethylene (PTFE). PFA's are known for being exceptionally corrosion resistant and inert at elevated temperatures. PFA nuts are inert to most chemical environments including organics, acids, bases, mixed chemicals and hyrdofluoric acid. Additionally PFA nuts are bio-inert and will not leach into or contaminate sensitive pharmaceuticals or food based products.
Compared to other high performance polymer nuts like PEEK or PVDF, PFA nuts offer the best all-around corrosion resistance especially at elevated temperatures. However the trade-off for its extraordinary corrosion resistance is its lower tensile strength compared to PVDF or PEEK nuts.
