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
• Biocompatible
• Extremely hydro-phobic and sheds water almost totally

Applications of PTFE Sleevings and Tubings:

1. Radars, Satellites and other defense electronics equipments
2. Due to high temperature proximity widely used for heater interconnections
3. Insulating cover for electrical joints, Motor winding leads and Transformer winding leads
4. Protective cover over electrical leads in Air-conditioning sealed units
5. RF Signal transmission, antennas
6. For branching leads in harness/cable assembly
7. In communications, control Instruments and professional electronics
8. As carriers for corrosive, high viscosity chemicals or fluids, also under high pressure and temperature
9. As protective cover over hoses for injection moulding machines
10. Hoses (with or without stainless steel wire braid) for hydraulic/pneumatic applications
11. As capillaries for medical application
12. Temperature sensors, Automobiles etc.
