What is Silicone-Free Thermal Grease
GALLOP INNOTEK silicone-free thermal grease usually relies on non-silicone polymers such as synthetic oils or ceramic fillers. This design helps you avoid common issues found in traditional greases, like oil bleeding, material migration, or circuit contamination during long-term use.
Features of Silicone-Free Thermal Grease
High Thermal Performance
One of the key strengths of GALLOP INNOTEK silicone-free thermal grease is its outstanding thermal performance. By using a non-silicone formula with engineered base oils and fillers such as aluminum oxide, boron nitride, or nano-scale conductive particles, it builds a stable and efficient heat transfer path.
At the same time, it maintains low thermal resistance, allowing heat to transfer more effectively from the chip to the heatsink, thereby ensuring the system’s long-term stable operation. Even under pressure, the grease maintains interface contact without drying out or hardening, giving you lasting and consistent thermal conductivity.
Avoid Silicone Migration
Thermal greases that rely on silicone often face migration issues. After long-term use, the oil may seep onto nearby components, leaving greasy deposits or even reaching electrical contacts. This will cause poor conductivity, short circuits, or reduced performance. Additionally, in high-end fields—such as optical lenses, precision sensors, or automotive electronics—silicone contamination poses a particular risk. It can lower insulation strength, damage optical parts, or interfere with sensor accuracy.
Fortunately, GALLOP INNOTEK silicone-free thermal grease avoids these problems entirely by eliminating silicone oil. The material remains stable even under harsh conditions, ensuring your equipment stays clean and reliable without the risk of oil spreading.
Furthermore, since it leaves no stubborn residue on device surfaces, it can significantly reduce your maintenance costs. As a result, if cleanliness and reliability are top priorities in your projects, silicone-free grease is the smart choice.
Wide Operating Temperature Range
Electronic devices are often exposed to extreme temperature conditions. Traditional silicone-based thermal grease will dry out, harden, or lose efficiency when temperatures fluctuate too much.
In contrast, GALLOP INNOTEK silicone-free thermal grease utilizes an optimized formulation that remains stable across a significantly wider temperature range, typically from -40°C to 180°C, with some advanced models capable of handling even more demanding limits. Therefore, whether your system runs in freezing cold or high heat, you don’t have to worry about cracking, evaporation, or sudden loss of performance.
With this capability, your products can be designed in various ways and deployed in complex environments without the risk of cooling failure caused by temperature swings. For example, in new-energy battery packs, silicone-free grease helps reduce the thermal gap between cells and the cooling system, extending battery life.
Low Outgassing
Silicone-based thermal grease releases low-molecular siloxanes at high temperatures. Once these compounds settle on optical parts or electronic contacts, they may reduce light transmission or cause poor electrical connections. Especially in vacuum equipment, optoelectronics, semiconductor production, and aerospace, low outgassing is not optional—it is a strict requirement.
GALLOP INNOTEK silicone-free thermal grease uses low-volatility organic bases, greatly reducing this risk. It maintains its composition stability even under heat and vacuum, thereby preventing performance loss after long-term use.
For you, low outgassing means higher reliability and fewer maintenance issues. It also helps you meet tougher environmental and safety regulations, making industry certification and audits much easier to pass.

Reasons for Choosing Silicone-Free Thermal Grease
Long Service Life
GALLOP INNOTEK silicone-free thermal grease is built with a low-volatility base and highly stable fillers. It remains steady across a range of temperatures, humidity levels, and thermal cycling, which significantly extends its service life. This can reduce the frequency of thermal conductive material replacements, minimize downtime, and lower maintenance costs.
For systems that must run nonstop—such as servers, power electronics, and new energy platforms—long-lasting, silicone-free grease provides more dependable cooling and keeps critical components stable for many years.
Suitable for Sensitive Devices
In industries such as medical, optical, and precision electronics, your equipment requires more than just efficient cooling. It also demands materials with exceptional cleanliness and long-term stability. For instance, take X-ray imaging devices—if the sensors aren’t kept clean and steady, diagnostic accuracy can suffer.
However, GALLOP INNOTEK silicone-free thermal grease keeps these applications contamination-free over time. After choosing silicone-free grease, you meet strict industry standards while shortening testing cycles and accelerating time to market. Meanwhile, it will give your products a clear edge in high-end sectors and help them stand out in a competitive field.
Environmental Friendly
GALLOP INNOTEK silicone-free thermal grease is formulated without silicone oil or other substances that may pose environmental risks, making it easier for you to meet international standards such as RoHS and REACH. Moreover, compared to conventional silicone-based products, it reduces its environmental impact throughout production, use, and disposal, while also providing a safer choice for your operators.
If you choose a silicone-free solution, your products can enter markets with strict environmental demands more smoothly, while also enhancing your brand image and aligning with the trend of sustainable development.
In most cases, high-quality silicone-free thermal grease won’t corrode common metals like copper or aluminum, nor plastics such as PC or ABS. Because its base is usually mineral oil or synthetic esters and very stable.
However, you should still make sure to select a grade compatible with your materials, especially under extreme temperatures or prolonged contact, to avoid any unwanted chemical reactions.
Silicone-free thermal grease can replace silicone-based types, but it depends on your application. It works especially well with electronics that are sensitive to silicone. But in extreme temperatures, its performance might be slightly below some premium silicone-based products.
Therefore, when switching, you should choose the right type based on your device’s cooling needs and material compatibility to get the best results.
