Heat Sink Thermal Paste
GALLOP INNOTEK thermal paste for heat sinks is a paste-like material that possesses high thermal conductivity and is generally used in heat sinks. The thermal paste is composed of a base compound, thermal conductive fillers, and other additives. Common base compounds include silicone grease and synthetic oil. Silicone grease has good stability, and it is difficult to volatilize. Different fillers have different thermal conductivities. You can choose the most suitable one according to your requirements.
Why Heat Sink Need Thermal Paste
Air Insulation
The air has a very low thermal conductivity. Although the heat sink appears smooth, it has numerous tiny gaps that allow air to pass through, potentially affecting heat conduction and decreasing heat dissipation efficiency. GALLOP INNOTEK thermal paste for heat sinks can fully fill these gaps, establishing a better thermal conduction process to help devices maintain a normal operating temperature.
Improve Thermal Conductivity
It is essential for the stable operation of heat sinks to dissipate heat efficiently in a timely manner. In a high-temperature environment, the working efficiency of equipment decreases, and electricity consumption increases, which in turn increases your costs. When the temperature of the equipment is too high to operate normally, it will cause overheating issues, and the component may be damaged. GALLOP INNOTEK thermal paste can significantly reduce the thermal resistance, making fast heat dissipation.
Extend Heat Sink Life
Electric products are sensitive to temperature; if they are exposed to high-temperature conditions for an extended period, the components will age, and their service life will be reduced. GALLOP INNOTEK thermal paste for the heat sink can efficiently control the work temperature of core components, and keep them in a normal condition. This not only avoids failures caused by heat dissipation issues but also improves your operational efficiency.

Types of Thermal Paste
Different types of thermal pastes exhibit distinct differences in performance, stability, or application scenarios. Choosing a proper one is beneficial for your project, as it improves heat dissipation efficiency and reduces maintenance costs. GALLOP INNOTEK thermal paste is classified into the following three types:
Low Volatile Thermal Grease
Low-volatility thermal grease is one of the most widely used conductors, and its primary advantage is that its composition is stable and does not easily volatilize. GALLOP INNOTEK low-volatility thermal grease has a low thermal resistance, and the outgassing is also low. It is designed for various applications, including GPUs, power transistors, and high-power density LED modules, among others, and has no corrosion or oxidation on any contact surface. If you pursue a cost-effective solution, GALLOP INNOTEK low-volatility thermal grease is a good choice.
Non-Silicone Thermal Grease
Traditional silicone thermal grease is easy to volatilize, leading to insulation failure or poor contact issues. GALLOP INNOTEK non-silicone thermal grease does not contain silicone grease to avoid damage from silicone grease volatilization. It also exhibits high thermal conductivity, allowing it to maintain stable performance even in harsh environments. The non-silicone thermal grease is commonly used in automotive electronic control units, power supplies, semiconductor cases and heat sinks, signal transmitters, and other products.
Premium Thermal Grease
Premium thermal grease is mainly used in such as military gadgets, laser equipment, routers, and wireless infrastructures. It consists of composite thermal conductive fillers, which give it high heat resistance and high heat conductivity. The premium thermal grease for the heat sinks of these products remains stable in high-temperature conditions and has a wet surface that is resistant to drying and cracking. Although the cost of GALLOP INNOTEK premium thermal grease is slightly higher, it significantly improves the efficiency and lifespan of the equipment, while also reducing your maintenance costs.
How to Choose Proper Thermal Paste
Thermal Conductivity
The thermal conductivity is one of the key factors to consider when choosing a suitable thermal paste, as it determines the speed and efficiency of heat sinks. Generally, GALLOP INNOTEK premium thermal grease has higher thermal conductivity than other products. However, when selecting the most suitable thermal paste, it is not just about pursuing high thermal conductivity; you should also consider evaluating it based on the actual power consumption and heat dissipation structure of the equipment.
Application Environment
Each type of GALLOP INNOTEK thermal paste for heat sink has a unique performance and a certain suitable application environment; you should analyze these factors comprehensively. For example, if you want to use the thermal paste in the electrical industry, it is best to avoid silicone grease.
Viscosity
Viscosity is also a crucial factor in selecting a suitable thermal paste. GALLOP INNOTEK low-volatility thermal grease possesses medium viscosity, while the other two have low viscosity. If the viscosity of the thermal paste is too low, it will flow easily and pollute the heat sink. While high viscosity makes it difficult to achieve uniform thickness. You should choose one type that is suitable for your process.
