Guide to Wire and Cable Insulation and Coverings

Which insulation Material?usable temperature rangeApplication Note
PVC-10°C to 105°CGood general-purpose insulation for "light" environments. Waterproof and very flexible.
PFA
(extruded)
-75°C to 250°CResistant to oils, acids other adverse agents and fluids. Good mechanical strength and flexibility. PTFE better for steam/elevated pressure environments
PTFE
(taped & wrapped)
-75°C to 250/300°CResistant to oils, acids other adverse agents and fluids. Good mechanical strength and flexibility.
Glassfibre (varnished)-60°C to 350/400°CGood temperature range but will not prevent ingress of fluids. Fairly flexible but does not provide good mechanical protection.
High temperature glass fibre-60°C to 700°CWill withstand temperature up to 700°C but will not prevent ingress of fluids. Fairly flexible, not good protection against physical disturbance.
Ceramic Fibre0 to 1000°CWill withstand high temperature, up to 1000°C. Will not protect against fluids or physical disturbance.
Glassfibre
(varnished)
stainless steel
overbraid
-60°C to 350/400°CGood resistance to physical disturbance and high temperature (up to 400°C). Will not prevent ingress of fluids.

For maximum accuracy extension cables should be used and terminals and connectors should be of thermocouple materials to maintain continuity.
