Thermal property testing is an essential part of ensuring the safe working limits of a material are met. It is also used to assess the materials’ general properties and likely lifespan. The ability to conduct heat transfer efficiently is a fundamental property of any material.
Thermal Conductivity
Thermal conductivity is one of the most important thermal properties that determine how heat is absorbed or released in different materials. It is essential to the proper functioning of a variety of devices and products in a wide range of industries, including electronics, automobiles, construction, and more.
The thermal conductivity of a material can vary greatly from one material to another. It is dependent on a number of factors, including its structure and the direction in which heat can travel within it. It is also important to note that some materials have anisotropic properties, which means they are more easily able to conduct heat in certain directions.
There are a variety of methods for determining the thermal conductivity of a material. Two of the most common are steady-state techniques and transient or non-steady-state techniques.
Steady-state techniques measure the temperature of a material during an extended period of time. The advantage of steady-state techniques is that they can provide more accurate results, since the signal remains constant over a wide range of temperatures.
Thermal Insulation
Thermal insulation is an important part of reducing energy consumption, as well as associated greenhouse gas emissions in buildings, process industries and in thermal appliances. Insulation helps to prevent heat loss from radiation, conduction and convection, which means that it reduces heating and cooling costs.
The primary limitation is that they take much longer to measure conductivity than transient methods. This is due to the fact that a heat flow meter must sample the material for an extended period of time in order to accurately determine its thermal conductivity.
C-Therm has designed a robust, easy to use HFM that offers industry a reliable, high-precision method for conducting thermal conductivity tests in a short period of time. This is a great solution for those looking to save time and expense on their thermal conductivity characterizations.
For many years, industry has standardized around characterizing the thermal conductivity of materials using steady state methods.
A number of cellular plastic insulation materials are available that offer both a low thermal conductivity and an excellent mechanical strength.
In addition, a number of advanced insulation materials such as vacuum insulation panels and microporous insulations are now available in the market. These innovative insulations have the ability to deliver significant energy savings while offering a wide range of advantages over traditional building envelope materials, including a lower energy footprint, higher durability and better fire safety. However, these products are only available at specific sizes and may require special consideration in the design phase.
Thermal Stability
Thermal stability is a critical property that influences the quality of a substance or product. It varies with storage conditions and environmental factors, such as temperature, light and humidity, and may also affect formulation and packaging.
Stability testing is necessary in many industries, including pharmaceuticals and consumer products. This requires that manufacturers know the thermal properties of their materials.
These processes can cause degradation of the materials, as well as other physical and chemical changes. These effects can impact the final product and could lead to failure of the materials during production.

Thermal Resistance
Thermal resistance is a measurement of the ability of materials to oppose the flow of heat. It is a valuable measurement for designers of electronics circuits as it helps to ensure that the circuit operates within its temperature limits and does not overheat.
This type of testing is also critical to industries that make use of metals and alloys. This thermal property testing is provided on a datasheet to help engineers operating the device ensure that they are maximizing their efficiency and longevity while limiting their risk of overheating.
It is important to understand that the heat resistance of a material depends on its thickness and thermal conductivity. For example, if we are looking at the thermal resistance of a piece of steel and we want to calculate its temperature difference to a surrounding object (in this case, the ground), we need to consider the thickness of the steel as well as the amount of heat that will be carried through it by convection and radiation.
