Overview
PTFE (Polytetrafluoroethylene) is an exceptional high-performance fluoropolymer known for its unparalleled chemical resistance, extremely low friction coefficient and non-stick properties. It performs reliably across a wide temperature range, making it suitable for demanding industrial applications involving extreme heat, cold or exposure to aggressive chemicals. PTFE is biologically inert and resistant to virtually all chemicals and solvents, which makes it a preferred material in the food, medical, chemical and electrical industries. Its self-lubricating nature and excellent dielectric properties make it ideal for dynamic and insulating components.
Key Features
- Outstanding chemical resistance to virtually all substances
- Very low coefficient of friction (non-stick surface)
- Extremely wide operating temperature range (-200°C to +260°C)
- Non-toxic and biologically inert
- Excellent electrical insulation properties
- High resistance to weathering, UV and moisture
- Non-flammable (meets UL 94 V-0 standard)
- Low surface energy (repels water, oils and most substances)
Applications
- Seals, gaskets and O-rings
- Valve seats and pump parts
- Electrical insulators and bushings
- Bearings and low-friction wear parts
- Chemical processing equipment linings
- Food-grade components
- Medical and pharmaceutical applications
- Laboratory tubing and containers
Weaknesses
- Poor mechanical strength compared to other engineering plastics
- Difficult to machine due to softness and creep
- Not suitable for load-bearing applications
- Very low wear resistance (unless filled or blended)
- Difficult to bond or weld without special treatment
