At NEDC, we cut thermal pads like it’s our job- cause guess what.. It is. Oftentimes, when we are talking to customers- they may not know exactly how thermal pads work because it may not be obvious what a good insulator air is in an application. A few weeks ago, right before Thanksgiving, we had an Omelet day at NEDC. The eggs are set in the pan through heat. They cook relatively quickly- but we were thinking- I think they’d cook a little better with a thermal pad.

 Setup of Experiment:

With that said, we thought we would do something a little bit more fun, and show how thermal pads work by cooking an egg through it. I asked our team for some constructive criticism of our comparison because as they all know, I’m somewhat of a “study snob” meaning, I ask if it was a double blind placebo- I ask how many people were in the study..amd sp pm.  So I wanted to make sure that we were being impartial here. Below are images of two things:

Egg 1:

No thermal pad

Egg 2: 

Gap Pad 5000S35 .020’’ thick between the saucer pan and the griddle.


The egg with the thermal pad cooked about 20% quicker, and maintained a temperature about 10 degrees lower on average after several measurements with our temperature gun. I ran this study twice to confirm the results.

How it Works:

A thermal pad is a much better conductor of heat than air. Air is a FANTASTIC insulator.. Almost anything is better than air- however, the thermal pad does two things:

  1. It wets out onto the saucer meaning the surface contact is better- helping conduct the heat to the egg to cook it quicker.
  2. The thermally conductive material implanted in the material- fillers such as ceramic, or diamonds will help conduct the heat to the egg quicker.
