Datasheet PTFE Tubing

PTFE is the most chemically resistant plastic known. Its mechanical

properties are low compared to other engineered plastics, but it can be

improved by adding fillers such as glass fiber, carbon, graphite and similar

materials. PTFE has almost ideal dielectric properties. Its dielectric

constant (2.1) and power-loss factor (0.0002) are low and remain so over a

wide range of temperatures and frequencies. In certain applications, such

as fuel hoses, some electrical conductivity is required to dissipate static

charges. When exposed to flame, PTFE decomposes leaving just a little

residue. PTFE is extremely inert and stable up to a temperature of 260 °C.

PTFE is also virtually unaffected by oxygen, ozone and UV light.
