- Greater Than 50% Deflection at 50 psi
- 1.2 W/(m K) Thermal Conductivity
Product Description
Tflex™ 3130 is a 3.25 mm-thick configuration of the Tflex™ 300 Series, a ceramic-filled silicone thermal gap filler designed to conform around components and bridge gaps between heat-generating devices and adjacent cooling surfaces. The light-green thermal interface material provides typical thermal conductivity of 1.2 W/m·K and deflects by more than 50% of its original thickness at 50 psi. Its highly compliant construction and low compression set make it suitable for filling larger interface gaps while maintaining effective thermal contact between electronic components and cooling hardware.
Key features
- Highly compliant construction: Deflects by more than 50% of its original thickness at 50 psi, supporting conformity around component topography.
- Thermal gap-filling performance: Provides typical thermal conductivity of 1.2 W/m·K when tested according to ASTM D5470.
- Broad thickness availability: Offered from 0.50 mm (0.020 in) to 5.08 mm (0.200 in), with standard and custom-converted formats available.
Applications / Suitable for
- Automotive electronics, infotainment, ADAS, and powertrain or ECU assemblies
- Routers and wireless infrastructure
- Notebooks, tablets, portable devices, gaming systems, and smart-home devices
- Instrumentation and drone or satellite electronics
