Which insulation Material?

usable temperature range

Application Note

PVC

-10°C to 105°C

Good general-purpose insulation for “light” environments. Waterproof and very flexible.

PFA

(extruded)

-75°C to 250°C

Resistant 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°C

Resistant to oils, acids other adverse agents and fluids. Good mechanical strength and flexibility.

Glassfibre (varnished)

-60°C to 350/400°C

Good 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°C

Will withstand temperature up to 700°C but will not prevent ingress of fluids. Fairly flexible, not good protection against physical disturbance.

Ceramic Fibre

0 to 1000°C

Will 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°C

Good 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.
