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
