Silex Thermally Conductive Silicone Sponge Sheets SIL-X-600-FFF

Silex material SIL-X-600-FFF is a thermally conductive closed cell silicone rubber sponge. This material offers thermal conductivity along with electrical isolation. SIL-X-600-FFF is the superior choice for gasketing and cushioning applications requiring critical thermal transfer/sealing.

Recommended Uses:

SIL-X-600-FFF is offered to fill the needs of an unsupported thermal transfer material in applications requiring clean release, enhanced thermal performance by filling air gaps, electrical isolation and vibration cushioning.


SIL-X-600-FFF is available in both sheets 915mm x 915mm and 915mm wide off the roll. Material can be supplied with an aggressive acrylic pressure sensitive adhesive or high temperature silicone adhesive on one side. As with all of our silicone sheets, SIL-X-600-FFF can also be converted into strips, seals, washers, gaskets and fabricated articles.  SIL-X-600-FFF is available in the following thicknesses; 0.8mm, 1.6mm, 2.4mm, 3.2mm, 4.8mm and 6.35mm. Please note that the 6.35mm is only available 915mm x 915mm sheet format.
