Thermally insulating tape at high temperature (350C)

Click For Summary
SUMMARY

The discussion centers on the search for a thermally insulating tape or gel capable of withstanding temperatures between 100°C and 350°C for use on a glass slide in thermal measurements. The user emphasizes the need for low thermal conductivity and a thickness of approximately 1mm. Most conventional tapes fail to endure temperatures above 200°C, prompting suggestions such as using aluminum foil as an alternative solution. The focus is on finding materials that maintain adhesive properties while providing effective thermal insulation.

PREREQUISITES
  • Understanding of thermal conductivity and its measurement
  • Familiarity with high-temperature adhesive materials
  • Knowledge of thermal insulation techniques
  • Experience with materials suitable for laboratory environments
NEXT STEPS
  • Research high-temperature adhesive tapes rated for 350°C
  • Explore thermal insulation materials such as aerogels and silicone-based products
  • Investigate the thermal properties of aluminum foil as an insulating layer
  • Learn about the impact of thickness on thermal insulation performance
USEFUL FOR

Researchers, engineers, and technicians involved in thermal measurement applications, particularly those working with high-temperature environments and requiring effective thermal insulation solutions.

Hi all,
I am looking for a tape or gel that is very thermally insulating and apply that on my glass slide to serve as a thermally insulating material. The work temperature is 100C to 350C and it should be able to work with clean water. Any recommendations?

"Glass slide" suggests microscope, implies very limited dimensions, or a requirement for low thermal conductivity. Do you have some "rough" idea of thickness, heat transfer rate, the like?

Although that is a microscope glass slide, I don't use it for microscope...I use it for my thermal measurement. My rough idea is that this tape should be sticky and can endure high temperature (350C). Most tapes I found cannot endure more than 200C. For the thickness, I suppose not too thick? like around 1mm? heat transfer rate needs to be low, since that is the most important requirement...

How about wrapping it in aluminum foil. Hoping transparency is not a whole surface requirement, in which case a small hole should do.
