PTFE SLEEVES

PTFE Sleeve
PolyTetraFluoroEthylene (PTFE) Sleevings and Tubings are intended for applications involving High Frequencies, High Temperature or both. PTFE have excellent electrical properties, which does not change over a wide range of frequencies, temperatures and humidity. These sleevings and tubings are manufactured by Tape Wrapping Sintering (TWS) process that enables these high flexibility and excellent mechanical stability.

Few advantages of PTFE Insulation are as follows:

  • Extremely stable at high temperatures and can be used continuously at –65°C to +250°C
  • Non-Flammable
  • High Dielectric strength
  • Virtually inert to almost known chemicals, UV radiation, oils, solvents and fluxes
  • Excellent anti-stick properties prevents the build up of sediments, and fungus
  • RoHS compliance
