Euro Technologies offers a wide range of thermally conductive gap filler that represents one of the most common family of thermally conductive interface material.
As it’s possible to deduce from its name, this product is used to fill the air gap between the surfaces of the component and heat sink. Euro Technologies owns a wide and complete product portfolio that allows to find the best solution for most of the possible applications.
Euro Technologies’ gap filler family offers a large range of thermal conductivity, starting from 0,8 W/mK till 8 W/mK. Euro Technologies’ gap filler gives to engineers and designers the possibility to adapt their works to the most dimensional system tolerance thanks to a vast range of thicknesses (from 0.25mm to 12mm).
High-Performance Thermally Conductive Gap Fillers for Electronic Thermal Management
Euro Technologies offers a wide range of thermally conductive gap fillers, representing one of the most versatile and essential product families among thermal interface materials (TIMs). As the name suggests, these soft, highly compliant materials are specifically engineered to bridge and fill air gaps between hot electronic component surfaces (such as CPUs, GPUs, MOSFETs, and power modules) and heat sinks or metal enclosures. Because air is an extremely poor conductor of heat k ≈ 0.026 W/(m·K), trapped air pockets create significant thermal resistance, causing device operating temperatures to rise rapidly. By replacing insulating air with a high-performance gap filler pad, design engineers establish a continuous thermal bridge that drastically accelerates heat dissipation.
Broad Conductivity Spectrum and Dimensional Tolerance Adaptability
Euro Technologies’ gap filler portfolio features a broad range of thermal conductivity options, extending from 0.8 W/(m·K) up to 8.0 W/(m·K). This comprehensive lineup provides electronics design engineers and thermal specialists with maximum flexibility to adapt their hardware layouts to complex system dimensional tolerances. With an extensive selection of thickness options ranging from 0,25 mm fino a 12 mm, our gap filler pads effectively absorb mechanical shocks, compensate for surface roughness, and minimize stress on delicate surface-mount components, making them ideal for automotive, telecommunications, medical, defense, and industrial electronics applications.
Frequently Asked Questions about Gap Fillers
Why are thermally conductive gap fillers preferred over traditional thermal grease in high-tolerance assemblies?
Gap filler pads offer superior compliance over thick, uneven air gaps (up to 12mm) without drying out, pumping out, or migrating over time, providing both electrical isolation and consistent thermal performance across wide mechanical tolerances.
How do I select the right gap filler thickness for my electronic design?
Select a pad thickness slightly greater than the maximum expected physical gap (typically 10% to 25% compression) to ensure complete surface contact and low thermal impedance without exerting excessive mechanical stress on delicate PCB components.
What custom converting options does Euro Technologies supply for gap filler pads?
Euro Technologies supplies custom die-cut shapes based on customer CAD drawings, kiss-cut parts on roll sheets for rapid assembly, fiberglass-reinforced pads for tear resistance, and options with or without adhesive backings.
