Insulation
Okonite-FMR is Okonite's trade name for its heat, moisture, flame and chemical resistant,
mechanically rugged ethylene-propylene insulating compound.
The properties of Okonite-FMR insulation substantially enhance the well known features
of ethylene-propylene rubber insulations.
Overall Jacket
The Okoseal (PVC) jacket is mechanically rugged and has excellent resistance to most
chemicals.
