PTFE tubing
Benetech delivers a wide range of PTFE tubing (and modified PTFE). Smooth or convoluted (spiral or parallel), in metric, inch and AWG sizes.
PTFE tubing can be delivered on straight lengths, coils or spools, cut lengths and pre-formed parts. The natural colour of PTFE tubing is milky white until slight transparent.
In our program we supply thinwall PTFE tubing clear and spaghetti tubing in many colors. Thinwall PTFE tubing in diameters from 0.25 till 25mm and spaghetti tubing between 0.25 and 8.25mm.
Key properties of PTFE tubing
- Excellent chemical resistance
- Working temperature -190°C to +260°C
- Greatest resistance to fatigue (Wöhler curve)
- FDA approved
- Flame resistant - UL94V0
- No stick
- Low coefficient of friction
- UV-resistant (does not age)
- Not hygroscopic (water absorption < 0,01%)
- Very good dielectric insulation properties Properties of PTFE can be improved by adding additives as carbon, graphite, glass etc.
