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 screws are made from the fluoropolymer polytetrafluoroethylene and are known for being exceptionally corrosion resistant and inert at elevated temperatures. PTFE screws are inert to most chemical environments including organics, acids, bases, mixed chemicals and hyrdofluoric acid. Additionally PTFE screws are bio-inert and will not leach into or contaminate sensitive pharmaceuticals or food based products.

Compared to other high performance polymer screws like PEEK or PVDF, PTFE screws 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 screws.

Screw Types: Flat Head Screws, Hex Cap Screws, Pan Head Screws, Set Screws, Socket Head Cap Screws
