Thermocouple thermal insulation

I saw many UM with insulated hot end with Kapton tape.

Wha is that ? Are they having some problems or there are good reason to do that ?

Insulating the hot end with woven fiber glass, silicone, or (in my case) silicone foam helps the heater and the PiD to maintain the temperature a bit better, and it helps in cases when the fan is blowing onto the head where it shouldn't, it helps keeping the printed piece cooler (less radiant heat from the head) and it saves some energy. insulation is optional, the UM works fine without.

the kapton tape (polyimide) is just a heat resistant tape used to hold the insulation. the tape in itself has zero insulation properties. it is also used as a printing surface.

Ceramic Fiber, Aluminium Foil Tape and other thermal insulation material are very effective to Insulating the hot end. It keep hot end hot and not let the heat out.
