PVC
is the lowest cost of all the insulations. Mostly used with
extension grade wire with the exception of ripcord, code
3, construction, which is T/C grade. Very easy to strip. |
Silicone
rubber is a soft, flexible and tough insulation. Moderate
in cost, it retains flexibility at lower temperatures and
has higher upper utilization temperature than PVC. Outstanding
fuel and solvent resistance. |
Teflon
FEP is not affected by most corrosives, lubricants or weather.
Moderate in cost, FEP will not crack or embrittle with heat
aging. Good for cryogenic use if not flexed. |
Teflon
PFA is higher in cost than FEP but has higher upper utilization
temperature. Resistant to most corrosives, lubricants and
weather. Good for cryogenic use if not flexed. |
Teflon
TFE is higher in cost than FEP but has higher upper utilization
temperature. Tape is helically applied and cured. Difficult
to strip. |
Kapton
is a high cost insulation. It is resistant to radiation. The
tape is helically applied and cured with FEP binder. Difficult
to strip. |
