This slide highlights some of the key parameters, such color which is black, one side tacky, thermal conductivity at 1 W/mK with shore hardness at 5 (on a 00 scale). The breakdown voltage for a 20mil product is at 1700 VAC (typical). Using ASTM D-5568 method with the waveguide testing, a signal at 2.4GHz has about 0.28 dB/mm absorption and at 5GHz, about 0.55 dB/mm absorption. Please note that in a customer application, part size and thickness will and can influence EMI performance. To give an idea of dB change, every 0.1dB is about a 2.8% reduction. This product is available in sheet or die-cut form.
