Tflex SF600

Silicone Free Thermal Gap Filler

Product Description

Compliant Silicone-Free 3.0 W/mK thermally conductive Gap Filler Tflex SF600 is a high performance silicone-free thermal gap filler with a conductivity of 3.0 W/mK. Tflex SF600 is designed for applications which are silicone sensitive. RoHS compliant. Standard Thickness Standard thickness is 0.010-inch (0.25 mm) through 0.140-inch (3.56 mm) and available in 0.010-inch (0.25 mm) increments. 0.010-inch is only available in custom cut parts (sheet material is not available). MATERIAL NAME AND THICKNESS Tflex indicates Laird Technologies brand thermally conductive elastomeric gap filler product. SF6xx indicates ˜SF600 series 3.0 W/mK material and xxx indicates thickness in mils (0.001-inches) Examples: Tflex SF620 = 0.020-inch thick material
