PTFE
PTFE (Poly tetra fluoro ethylene) is a high performance engineering specialty polymer having exceptional properties with regard to chemical inertness, heat resistant, frictional properties & excellent electrical insulation characteristics etc. PTFE is a polymer that is mostly used in chemical, mechanical, electronics & electrical industries due to its unique properties:
- Chemical inertness to all known chemicals however attacked by molten alkalis, metal, chlorine, fluorine, related fluorine complexes at elevated temperature and pressure
- Wide operating temperature range - 250 C to + 260 V at atmospheric pressure
- Non-toxic & antis tick properties
- Resistance to solvents, insoluble in all solvents up to 260 C certain high fluorinated oils swells & dissolve PTFE at temperature close to crystalline melting point.
- Negligible water absorption
- Excellent weathering resistance
- Outstanding electrical/insulating properties over wide frequency range
- Non-flammable
- Resistance to radiation: electrical properties remain practically unchanged during & after irradiation, both in air & vacuum
- Virgin PTFE
- Soft PTFE (Expanded PTFE)
- Glass filled PTFE
- Carbon filled PTFE
- Graphite filled PTFE
- Bronze filled PTFE
