Outstanding chemical resistance at elevated temperatures
- Virtually inert to most organics, acids and bases
- Usable up to 260°C / 500°F but weakens significantly
- Excellent electrical insulator
- High purity for sensitive pharmaceutical and food type applications
- PTFE material datasheet
PTFE nuts are made from the fluoropolymer polytetrafluoroethylene and are known for being exceptionally corrosion resistant and inert at elevated temperatures. PTFE nuts are inert to most chemical environments including organics, acids, bases, mixed chemicals and hyrdofluoric acid. Additionally PTFE 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, PTFE nuts offer the best all-around corrosion resistance especially at elevated temperatures. However the trade-off for its extraordinary corrosion resistance is the lower tensile strength compared to PVDF or PEEK nuts.
