What is Silicone Free Gap Filler
Silicone-free gap filler is a thermal interface material free of silicone components, typically formulated from polyurethane or acrylic-based materials. You might find its appearance reminiscent of modeling clay, but it’s far more useful than that. It boasts exceptional thermal conductivity, requires no refrigeration at room temperature, and avoids settling issues common in thermal pastes—no stirring needed before use.
Additionally, GALLOP INNOTEK ‘s product features a syringe-style packaging for easy application, making it ideal for tight gaps.
What are the Advantages of Silicone Free Gap Filler you Should Know?
Excellent thermal conductivity: Silicone-free gap filler exhibits excellent thermal conductivity, with a thermal conductivity coefficient reaching 8.0 W/m·K. It effectively dissipates heat from electronic components, ensuring stable device operation.
Do not release Siloxanes: The formulation of silicone-free gap filler reduces the risk of volatile siloxane emissions, making it suitable for silicone-sensitive environments without causing equipment damage, while maintaining excellent performance during maintenance operations.
GALLOP INNOTEK ‘s GTP series silicone-free gap filler doesn’t release siloxanes, too. It also can cure rapidly to provide swift sealing for your equipment, shielding it from various corrosive elements.
Easy to store: Non-silicone gap filler has minimal storage requirements, it can be kept at room temperature at the range of 0-35℃ and boasts an extended shelf life. You needn’t worry about prolonged disuse will significantly affect its performance.

How does a Silicone Free Gap Filler Work?
Similar to other thermal interface materials, silicone-free gap fillers achieve efficient heat transfer by filling the air gap between heat-generating components and heat sinks. This promotes component cooling to maintain normal device operation.
Where is Silicone Free Gap Filler Used—-the Applications
Electronic Devices
Silicone-free gap filler can be applied to thermal management in gaps of LED lighting equipment, server racks, mobile phones, and other devices.
Optical Components
Moreover, silicone-free sealants prevent fogging when used in optical components like cameras and mobile phone screens, etc. This is particularly crucial for automotive displays, as every component in a vehicle directly impacts user safety.
Automotive Applications
Silicone-free gap filler is suitable for numerous automotive components, such as sensors, seats and so on. Compared to other thermal interface materials, this solution offers greater flexibility, enabling application in even the tightest corners and crevices within vehicle interiors.
How to use silicone free gap filler?
First, you should clean the surface where the gap filler will be applied, ensuring no oil or other contaminants remain, as these can reduce contact area and compromise thermal conductivity.
Then, you can apply the gap filler. The syringe-style packaging allows precise application into narrow gaps. In order to ensure the full contact between the gap filler and the surface, you need to apply it with even pressure, and allow sufficient time for curing.
The curing process typically takes approximately 24 hours. And you don’t need to do some additional actions during this, just leave it undisturbed at room temperature. If the gap is deep or the environment temperature is low, the curing time may need to be extended.
If you have any problems when using the silicone-free gap filler, GALLOP INNOTEK welcomes your call.
How to Choose Your Desired Silicone Free Gap Filler
You’ll find there are numerous manufacturers producing thermal conductive sealants on the market. The primary difference between sealants from different manufacturers lies in their varying specifications, which may be related to factors such as the density of the thermal conductive materials they contain. So how can you select the most suitable product in such a vast thermal conductive filler market? Here are some aspects to consider.
Observe The Thermal Conductivity
Typically, manufacturers will provide you with essential product specifications, and thermal conductivity is one such parameter. You can compare the thermal conductivity values of fillers produced by different manufacturers and select the most suitable option based on your budget.
GALLOP INNOTEK ‘s gap fillers feature thermal conductivity ranging from 1 to 8 W/m·K, offering multiple options to support your business.
Check Whether it is Within The Expiration Date.
Of course, just like choosing other products, you should ensure that the thermal interface material you select is within its shelf life and avoid purchasing expired items. This is key to ensuring they perform effectively.
Know About its Working Temperature
Generally speaking, non-silicone gap filler can operate at temperatures ranging from below freezing to over 100 degrees Celsius. The most important thing for you is to clearly define the applications and select the most suitable product based on the temperature range of the specific environment.
Traditional silicone gap filler present numerous limitations in practical applications. For instance, they may release silicone-containing gases during use, posing significant hazards in silicone-sensitive environments. Such emissions can cause electronic equipment malfunctions and weaken the adhesion of components on work surfaces. Furthermore, another shortcoming is that they dry out over time, leading to a deterioration in performance.
As we mentioned before, it is recommended for Electronic devices to use silicone-free gap filler because silicone-based thermal fillers can cause silicone oil volatilization and leakage. These phenomena damage electronic components, impair performance, and shorten device lifespan. Silicone-free sealants eliminate this risk by containing no silicone, making them suitable for all silicone oil-sensitive electronic components.
Moreover, silicone-free sealants offer superior electrical insulation and sealing properties, preventing current leakage or external electromagnetic interference. Most silicone-free sealants also feature rapid curing capabilities, forming a robust seal within a short time and significantly boosting production efficiency.
So if you are looking for silicone free gap filler for your own electrical equipment or business, you can take GALLOP INNOTEK ’s products into consideration.
