Phase change materials are used to deal with the thermodynamic phenomenon of phase changes. This means that they are capable of melting or subliming at a specific range of temperatures. They are used in refrigerators, insulation, cooling pads, and even some clothing. If you’re looking for a material with a specific thermal property, it is likely there is a phase change material for you. Explore the different types of phase change material suitable for many applications below!
The benefits of using phase change materials
Phase change materials have a variety of different uses. They can be used as insulation, for cooling pads, and even in some types of clothing. But they also offer a variety of other benefits. For instance, if you’re looking for a material with a specific thermal property (i.e., high or low heat conductivity), there is likely a phase change material for you. And if you’re looking to keep your product cool without too much additional cost, phase change materials are the way to go; it is only necessary to use one ounce per every ton of insulating material.
Types of phase change materials
There are many different types of phase change materials.
-Gel Phase Change Materials: These are the most common type of phase change material. They are usually made with a mixture of water and ethylene glycol, which is why they are sometimes called ‘water in oil’ materials. They have a low thermal conductivity which makes them ideal for insulation.
-Solid Phase Change Materials: These materials are also called ‘solid state’ materials because they never melt or sublimate completely. Instead, these materials go through a process called heterogeneous nucleation, where the solid becomes liquid over time. One example of this type is calcium chloride pellets, which often used in refrigerators and freezers to keep food cold with little or no electricity.
-Liquid Phase Change Materials: These materials behave like ordinary liquids when they reach their melting point (i.e., 100°C). Once they reach their melting point, they can cool things down by absorbing heat, then release it once it is below its melting temperature again (i.e., 20°C). This is what makes them perfect for cooling pads or clothing that utilizes evaporative cooling.
Solid-solid phase change material
Solid-solid phase change materials are the most common type. This means that they are able to change from solid to liquid or liquid to solid. These are ideal for thermal storage, insulation, and cooling pads. One example of a solid-solid material is paraffin wax.

Solid-liquid phase change material
A solid-liquid phase change material can be used for everything from food storage to insulation. It is capable of storing heat, which means that it will absorb heat when the temperature increases. This means that it can also release heat when the temperature decreases, making it a great choice for insulation.
Phase change material types
There are four different types of phase change materials:
Solid to liquid: This type of material changes from a solid to liquid state when heated. This is the most common type of phase change material and can be found in refrigerators, insulation, cooling pads, and even some clothing.
Examples: Salt, ice, water
Solid to gas: This type of material changes from a solid to gas state when heated. The resulting gas is often harmless but can be corrosive or toxic if it contains nitrogen oxides. Examples: Propane, butane
Liquid to solid: This type of material changes from liquid to solid state when cooled. It is often used for insulation purposes in buildings because the layers are thin enough that they don’t hamper airflow too much. Examples: Styrofoam
Liquid to gas or vapor: This type of material changes from liquid to gas or vapor state when cooled down. Liquid-to-gas materials are usually ozone-friendly while liquid-to-vapor materials are not always ozone friendly depending on what they contain

Phase change materials work by absorbing heat and releasing it at a lower temperature. The most common type of phase change material is water, which absorbs heat and releases it as vapor. This process is called phase change, and it happens at a specific cooling point called the “triple point”. When the temperature falls below the “triple point”, water will turn into ice and release heat. This process is also reversible—when water reaches higher than the triple point temperature, it will turn into gas and release heat.
