Description
UniGap 1700US is an ultra soft gap filling material formulated to thermally connect sensitive components and devices to nearby metal work or a cold wall. UniGap 1700US delivers excellent vibration dampening properties that protect pressure sensitive heat generating components from dimensional changes. Its softness allows for varying component heights and sizes to conform to the surface texture of the material. UniGap 1700US delivers 1.7W/mK thermal conductivity and is ideal for applications that require a combination of good temperature stability, large temperature excursions and vibration dampening.
Benefits
- Superb elastic reverse properties and soft surfaces protects sensitive components from dimensional changes and pressure exertions during operation
- Interfacial thermal resistance is reduced to a minimum
- Compliant and easy to apply
Features
- Extremely compliant and electrically insulating
- Thermal conductivity = 1.7W/mK
- Naturally tacky, no need for adhesive
- Softness permits coupling of multiple height components to nearby metal work
Recommended Uses
- Any gap filling requirement where heat generating components are sensitive to pressure changes. Cooling power devices in AC-DC and DC-DC PSUs. Cooling digital signal processing (DSP) units.
