PTFE (Polytetrafluoroethylene) The combination of chemical and physical properties of PTFE is a consequence of its true fluorocarbon structure. This unusual structure leads to a material which has an almost universal chemical inertness; complete insolubility in all known solvents below 300°C; excellent thermal stability; and unsurpassed electrical properties, including low dielectric loss, low dielectric constant and high dielectric strength. Furthermore, PTFE does not embrittle at very high or at very low temperatures.
ADVANTAGES
- High Performance from -200°C to 260°C (Peak 300°C)
- Unaffected at soldering temperatures; Autoclavable
- Suitable for High-Density wiring
- Smooth Internals allow closer fit
- Superior Tape-Wrapping-Sintering (TWS) Method provides good mechanical stability, high burst pressure and long flex-life
- High Dielectric Strength
- Resistant to UV Radiation
- Fire non-propagating
- Inert to almost all chemicals (few exceptions), solvents, fluxes, oils; Zero extractables
- Freedom from Ageing, Fungus and Water Absorption
- Biocompatible
