PTFE Sheets
Virgin and filled Polytetrafluoroethylene (PTFE) sheeting engineered for extreme chemical inertness across the entire 0-14 pH spectrum, ultra-low friction (0.04), and continuous temperature capability from -200°C up to +260°C.
Types & Configurations of PTFE Sheets
Virgin Grade Skived PTFE Sheets
Ultra-clean high-dielectric continuous rolls from 0.25mm to 3.0mm thickness for gasket cutting.
Moulded Compression PTFE Plates
Thick 5.0mm to 100mm heavy plates for chemical pump bases and structural bridge slide bearings.
Glass-Filled PTFE Sheeting (15% & 25%)
Engineered compound significantly reducing cold flow creep under heavy compressive flange bolting.
Carbon & Graphite Filled PTFE Sheets
Electrically dissipative and high thermal conductivity sheets for flammable solvent tanks.
Bronze-Filled PTFE Wear Plates
60% bronze powder filled plates delivering maximum compressive strength for machine tool slideways.

Material Selection & Properties
We offer specialized compound formulations tailored to chemical media, thermal extremes, static deflection, and dynamic fatigue requirements. The best material depends on your operating environment and required service life.
| Material / Polymer | Key Engineering Properties | Recommended Applications & Considerations |
|---|---|---|
| Virgin PTFE (Teflon™) | Universal chemical inertness (pH 0-14), temp up to +260°C | Pharmaceutical seals, cryogenic valve seats, gaskets |
| 15% / 25% Glass-Filled PTFE | Reduced creep/cold flow under compressive mechanical load | Hydraulic backup rings, cylinder piston wear bands |
| Carbon / Graphite Filled PTFE | Low friction, high thermal conductivity, dry running | Compressor rider rings, dynamic rotary shaft lip seals |
| Bronze-Filled PTFE (40% / 60%) | Maximum compressive strength & thermal dissipation | Heavy hydraulic guide rings, high-pressure piston cups |
| Modified / TFM PTFE | Lower permeation, smoother surface finish, higher fatigue | Semiconductor ultra-pure valves, diaphragm pumps |
