Description
Flat bar in white PTFE (Teflon), already cut to width and length: machine it directly into guides, slide pads and flat parts. It is the material with the lowest coefficient of friction of any solid and the broadest chemical resistance of all: very few substances attack it and it works from -200 to +260 °C.
- Thicknessesfrom 6 to 40 mm
- Widthsfrom 20 to 150 mm
- Lengths1200 mm
- Operating temperature*-200 / +260 °C
- Density*2.20 g/cm³
The material
PTFE is non-stick, non-wettable and an excellent insulator; it can be machined but is soft, so tight tolerances require care. It is chosen for chemistry and temperature, not for mechanical strength: under constant load it "cold-flows".
Typical applications
Operating conditions
| Service temperature* | -200 / +260 °C continuous |
|---|---|
| Resists | Practically all chemicals, including concentrated acids and alkalis, solvents and oxidisers |
| Avoid | High static loads (it cold-flows), structural applications, gluing without surface treatment |
| Water absorption* | < 0.01 % — nil for practical purposes |
| Hardness* | 55-60 Shore D |
| Tensile strength* | 20-30 MPa |
| Density* | 2.20 g/cm³ |
| Food contact | Yes, listed by the shop for food use |
Advantages
- The lowest coefficient of friction of all
- Inert to almost all chemicals
- Very wide temperature range, from -200 to +260 °C
- Non-stick, non-wettable
Limitations
- Cold-flows under constant load (creep)
- Mechanically soft, not suitable for structural functions
- Cannot be glued without surface treatment
- High cost compared with other engineering plastics

Technician's tipIt is chosen for chemistry and temperature, never for mechanical strength. If the part must carry a constant load, you need grades filled with glass, carbon or bronze.
* Typical values from technical literature for this material, indicative and not measured on the individual batch: for critical uses ask us for the manufacturer's data sheet. The full technical data sheet for the material, in Italian, can be downloaded with the "Datasheet" button at the top.
