The company's ARclad(r) 90038 and Flexshield(r) 8269 are said to be highly conductive pressure-sensitive tapes designed for electromagnetic interference (EMI) shielding. The ARclad 90038 is a 2.4-mm acrylic-based tape, featuring a 1-oz, tin-plated, copper-foil backing. Its shielding effectiveness ranges from 95 to 80 dB in the 1 to 18 GHz frequency range. The tape's tin-plated backing can be soldered, and is reportedly resistant to corrosion and oxidation. The Flexshield 8269 is a 4-mm tape featuring an Electron(r) nickel copper-plated woven polyester fabric carrier. The tape's shielding effectiveness is 90 to 80 dB in the 1 to 18 GHz frequency range.
