Few notable properties are as under:
1. Non-Flamability:
The Insulation is fire (Flame) proof i.e. non-flamable.

2. Flexibility:
P.T.F.E. wires are manufactured with best available stranded copper wires, giving better flexibility for comfortable use in the wiring.

3. Working Temp.:
It's working Temperature range is (-) 60° C to (+) 260° C.

4. Weather Resistance:
The insulation have not shown any notable changes in it's electrical, mechanical or chemical properties even after out door exposure for over 20 years. It is also unaffected by exposure to ultraviolet rays.

5. Chemical Resistance:
Insulation is inert to virtually all known Acids, chemicals and solids.

6. Electrical Stability:
Insulation electrical properties do not change even after long-term heat aging. Insulation has low dielectric constant and dissipation factor, it's high dielectric strength and insulation resistance shows minimum changes over wide temperature, frequency and voltage fluctuations.

7. Space Saving:
P.T.F.E. wires is of less O.D. for the same current carrying capacity of PVC Insulated wires, thus saves space to facilitate more no. of insulated wires in the same conduit. It's smooth surface also facilitates easy conduit pull.
We defined few properties as above, but PTFE Insulated wires have more unique properties such as antistic, non-contaminating, non-toxic, resistant to fungus, non-wet, resistant to impact, tearing, abrasion, cut-through and cold-flow etc.
