TM Tflex HD400 Series Thermal Gap Filler Product Description Laird Tflex HD400 is a 4.0 W/mK gap filling material in our high deflection line of products. Tflex HD400 is an excellent choice when wide manufacturing tolerances occur. These variable gaps can be filled with Tflex HD400 while generating minimal board and component stress. Lairds unique manufacturing capabilities, filler and resin knowledge result in this advanced product designed with customer applications in mind. Tflex HD400 is provided in thickness from 0.5mm (.020) up to 5mm (0.200) in 0.25mm (.020) increments as standard. In addition, Laird can provide Tflex HD400 in multiple converted formats through approved converters and distribution networks. FEATURES AND BENEFITS 4.0 W/mK thermal conductivity Low pressure versus deflection Excellent surface wetting for low contact resistance Minimizes board and component stress Large tolerance applications RoHS and REACH compliant SPECIFICATIONS TYPICAL PROPERTIES VALUE TEST METHOD Construction & Composition Ceramic filled silicone sheet N/A Color Blue Visual Thickness Range 0.5 mm (0.020) - 5.0mm (0.20) N/A Thermal Conductivity (W/mK) 4.0 ASTM D5470 Density (g/cc) 3.0 Helium Pycnometer Hardness (Shore 00) 44 ASTM D2240 Outgassing TML (weight %) 0.22 ASTM E595 Outgassing CVCM (weight %) 0.04 ASTM E595 Temperature Range -40C to 200C Laird Test Method Rth 40 mils, 10 psi 0.36Cin2/W ASTM D5470 (Modified) Dielectric Constant 1 MHz 10.7 ASTM D150 UL Flammability Rating V-0 UL 94 14 Volume Resistivity 2.8 x 10 ASTM D257 Americas: +1.866.928.8181 Europe: +49.(0).8031.2460.0 Asia: +86.755.2714.1166 www.lairdtech.com TM Tflex HD400 Series Thermal Gap Filler Tflex HD400 Deflection vs Pressure 90% 80% 70% 60% 50% 40% 30% 20% 10% 0% 5 psi 10 psi 20 psi 30 psi 40 psi 50 psi 60 psi 70 psi 80 psi 90 psi 100 psi 40 mil 60 mil 140 mil 180 mil 200 mil Tflex HD400 Thermal Resistance vs. Pressure 0.70 C-in2/W 0.60 C-in2/W 0.50 C-in2/W 0.40 C-in2/W 0.30 C-in2/W 0.20 C-in2/W 0.10 C-in2/W 0.00 C-in2/W 0 psi 20 psi 40 psi 60 psi 80 psi 100 psi 40 mil 60 mil 80 mil 100 mil AVAILABILITY STANDARD THICKNESSES 0.5 mm (0.020) to 5.0mm (0.200) thick material available in 0.25mm (0.010) increments Available in standard sheet sizes of 18 x 18 and 9 x 9 or custom die cut parts OPTIONS DC1 eliminate tack from one side PART NUMBER SYSTEM Tflex indicates Laird elastomeric thermal gap filler product line.
