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 fasteners & flanges are made from the fluoropolymer polytetrafluoroethylene and are known for being exceptionally corrosion resistant and inert at elevated temperatures. PTFE fasteners & flanges are inert to most chemical environments including organics, acids, bases, mixed chemicals and hyrdofluoric acid. Additionally PTFE fasteners & flanges are bio-inert and will not leach into or contaminate sensitive pharmaceuticals or food based products.
Compared to other high performance polymer fasteners & flanges like PEEK or PVDF, PTFE fasteners & flanges 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 fasteners & flanges.
