Why PTFE is Preferred in Demanding Applications
PTFE (Polytetrafluoroethylene) offers an exceptional property profile unmatched by most engineering plastics:
- Chemical inertness — Resistant to virtually all chemicals
- Temperature range — -180°C to +260°C continuous service
- Low friction — Lowest coefficient of any solid material
- Non-stick — Nothing sticks to PTFE surfaces
- Electrical insulation — Excellent dielectric properties
- UV resistance — Outdoor applications without degradation
Chemical Processing
PTFE components are essential in chemical plants where corrosive media destroy metal parts:
- Linings — Tank linings, pipe liners
- Seals and gaskets — For aggressive acid/alkali service
- Pump components — Impellers, shafts, bearings
- Valve seats — PTFE handles chemicals that destroy metal valves
"PTFE is the material of choice when we need to handle HF acid and other highly corrosive chemicals." — Chemical plant engineer
