PTFE Sleeves/Tubing

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
