Thermocouple Wire - Insulations - Plastic

Type
 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.
