What is Thermal Gel
GALLOP INNOTEK thermal gel, also known as thermal gel or heat sink gel, is a paste with high thermal conductivity. It is used as a thermal interface material to fill in between the heat sink and the heat source. GALLOP INNOTEK thermal gel helps the heat source achieve effective heat dissipation, improving the stability and safety of your equipment.
Thermal Gel Properties
Good thermal conductivity: GALLOP INNOTEK Thermal gel is a polymer with highly thermally conductive fillers, giving it excellent thermal conductivity.
Low thermal impedance: GALLOP INNOTEK Thermal gel is thin and has a low thermal impedance for good heat dissipation.
Good insulation: Most of the fillers added to GALLOP INNOTEK Thermal gel are non-conductive, such as Aluminium Oxide and Aluminium Nitride. Only some of the metal-containing thermal gels are conductive.
Fully cured: GALLOP INNOTEK Thermal gel has a short curing time and is very durable when fully cured.
Ultra-low compression force: GALLOP INNOTEK Thermal gel is very fluid and virtually non-hard, and can be compressed into a wide range of shapes and thicknesses, and completely fill small voids.
Reworkable: GALLOP INNOTEK thermal gel has a certain viscosity, but does not bond to the component like thermal grease. So it can be easily peeled off without damaging the surface of your components.
Cost-saving solutions: GALLOP INNOTEK’s thermal gel offers excellent performance for your project without straining your budget.
Resistant to Temperature Changes: GALLOP INNOTEK offers thermal gel that can withstand both high and low temperatures; you can use it in environments ranging from -50 to 150 degrees Celsius without any reduction in its performance.
Automated production: GALLOP INNOTEK’s thermal gel is flexible enough to be applied to a wide range of surfaces without the need for customised controls, allowing for efficient automated production using dispensing machines.
Wettability: Thermally conductive gels are flexible, even when fully cured, and neither greasy nor dry, with the ability to adhere.
Function of Thermally Gels
Filling Gaps
The surface of the element is difficult to achieve complete flatness. It has tiny voids that prevent the heating element and heat sink from making full contact. Small gaps can also be filled with air, which is a non-thermal conductor. GALLOP INNOTEK thermal gels are fluid and soft enough to fill the small gaps in complex surfaces, replacing air.
Improve Heat Transfer Efficiency
GALLOP INNOTEK thermal gels not only replace non-thermally conductive air but also increase the contact area between the heating element and the heat sink. This significantly enhances the efficiency of heat transfer, leading to improved heat dissipation for your electronic devices.
Enhance Equipment Reliability
Your electronic equipment generates a significant amount of heat when in operation, and if you don’t take measures to dissipate the heat in a timely manner, it will easily cause the heat to accumulate. Long-term exposure to high temperatures can lead to reduced performance or even damage. GALLOP INNOTEK thermal gels control the operating temperature of your electronic devices to enhance their stability.
Extend Equipment Life
If you use electronic equipment at high temperatures for extended periods, it can significantly reduce its lifespan. Repairing and replacing them will cost you more. The use of high-performance GALLOP INNOTEK thermal gels reduces the impact of temperature on the service life of your equipment.
Lower Noise
For high-performance electronic devices, the operation and heat dissipation of the device can generate noise that affects the experience of using your product. GALLOP INNOTEK thermal gels reduce the noise generated by the operation of your product while maintaining better heat dissipation。
Thermal Gel Types
- One-component thermally gel: The one-component thermally conductive gels are applied directly at the point of application and require curing at room temperature or under heat, for example. Due to the simplicity of the operation, large-scale production can be automated.
- Two-component thermally gel: The two-component thermally conductive gel consists of an A component and a B component, which need to be mixed evenly in proportion when used. They are cured by a chemical reaction immediately after mixing.
Applications of Thermal Gels
- Electronic devices: Use GALLOP INNOTEK thermal gels in mobile phones, tablets, and computers for fast heat dissipation. It is also lightweight and does not affect the portability of electronic devices.
- LED lighting: The heat generated by the operation of high-power LEDs affects their brightness and lifetime. GALLOP INNOTEK thermal gels are used to dissipate heat quickly.
- Precision instruments, including medical equipment and precision measuring instruments, are highly sensitive to temperature variations. The use of GALLOP INNOTEK thermal gels enhances measurement accuracy.
- Industrial electrics: Equipment such as transformers, switching power supplies, and charging piles also requires thermally conductive gels to dissipate heat for their operation.

The thermal gel composition has no harmful substances. It is stable and reliable in high and low temperature environments. Additionally, it is electrically insulating, allowing for safe use in electrical circuits.
Thermally conductive gel and thermally conductive putty are both thermal interface materials, but they differ in their properties. Thermal putty also fills the space between the heating element and the heat sink, helping to conduct heat. However, it is less fluid and is typically used to fill larger voids and uneven surfaces, as well as to provide anti-vibration cushioning.
Both thermal gels and thermal adhesives conduct heat for heating elements. However, thermally conductive gels are highly adhesive and can be used to hold components and heat sinks in place. Whereas the viscosity of thermal gels only results in good adhesion and requires the screws to secure the element and heatsink.
