Americas: +1.866.928.8181 Asia: +86.755.2714.1166 www.lairdtech.com PRODUCT DESCRIPTION Tflex™ HD700 thermal gap filler combines 5 W/mK thermal conductivity with superior pressure versus deflection characteristics. The combination will allow minimal stress on components while also yielding low thermal resistance. As a result, less mechanical and thermal stresses will be experienced within your device. Tflex™ HD700PI can be provided with an integrated polyimide film on one side. This liner provides numerous application benefits like electrical isolation, placement ease during assembly, and tear resistance for applications that require shear. Tflex™ HD700 and Tflex™ HD700PI are available in thickness from 0.5mm (0.020”) to 5mm (0.200”). The standard material Tflex™ HD700 material is a light pink color, but we do have the option to provide this in a grey color if a neutral color is desired (Tflex HD700,GR). Laird can provide material to meet your production needs in any region through our local production facilities. Please contact your local Laird sales or field engineering contact for samples or questions. FEATURES AND BENEFITS 5.0 W/mK thermal conductivity Low pressure versus deflection Excellent surface wetting for low contact resistance Minimizes board and component stress Option for additional electrical isolation and tear resistance Environmentally friendly solution that meets regulatory requirements including RoHS and REACH SPECIFICATIONS TYPICAL PROPERTIES VALUE TEST METHOD Construction & Composition Ceramic filled silicone sheet N/A Color Pink (*Option for Dark Grey) Visual Thickness Range 0.50mm (0.020”) 5.0mm (0.20”) N/A Thickness Tolerance +/- 10% N/A Thermal Conductivity (W/mK) 5.0 ASTM D5470 Density (g/cc) 3.3 Helium Pycnometer Hardness (Shore 00) 54 ASTM D2240 Outgassing TML (weight %) 0.23 ASTM E595 Outgassing CVCM (weight %) 0.07 ASTM E595 Temperature Range -50°C to 200°C Laird Test Method Rth@ 40 mils, 10 psi 0.287°C–in2/W ASTM D5470 (Modified) Dielectric Constant @ 1 MHz 5.01 ASTM D150 UL Flammability Rating V-0 UL 94 Volume Resistivity 1.4x 1014 ohm-cm ASTM D257
