These were purchased from an electronics liquidator earlier this year, and they were received brand new and clean in the original factory boxes. We repackaged them in 4-mil Ziplok bags for resale. Best we can determine, these are some kind of Boron Nitride material bound in a very soft silicone elastomer. The result is an amazing material which is not only an effective and pliable electrical insulator, but which also absorbs and diffuses heat like a heatsink.
The manufacturer describes the firmness as 25 Shore OO. Near as we can research, the Shore OO scale is used to rate the hardness of foam rubbers and other soft materials. In layman\'s terms, it is relatively heavy and very soft to the touch, but not exactly rubbery. It stays intact and holds its shape when handled and bent slightly, yet it can be easily cut or torn. It is somewhat tacky when you first peel off the protective plastic, and the more you handle it the tackier it seems to get. If you knead a piece with your fingers, it molds together almost like a stiff putty -- maybe a little stiffer and less sticky than biscuit dough. There is little to no odor, and the only handling precaution on the datasheet is not to get it in your eyes. Notwithstanding, I still wouldn\'t suggest feeding it to the kids. It feels cold and clammy to the touch due to its extreme heat absorption properties. Having said all that, it should be perfect for dissipating heat from densely populated circuit board components.

According to the manufacturer:
Item # Tflex 6100, Tflex™ 600 Series Gap Filler Material
Tflex 600 Series™ is an exceptionally soft, highly compressible gap filling interface pad with a thermal conductivity of 3.0 W/m-K. These outstanding properties are the result of a proprietary boron nitride filler in the composition.
The high conductivity, in combination with extreme softness, produces incredibly low thermal resistances. While extremely soft, Tflex 600 recovers to over 90% of its original thickness after compression under low pressure.
Tflex 600 is naturally tacky and requires no additional adhesive coating that can inhibit thermal performance. Tflex 600 is electrically insulating, stable from -45ºC to 200ºC and meets UL 94HB rating.
