Z-3250-CN EMI shielding fabric is a .004-inch-thick, woven Nickel over copper-plated polyester taffeta cloth that provides outstanding EMI shielding performance. The thin-woven polyester construction makes Z-3250-CN extremely flexible, yet very strong, and provides excellent corrosion resistance and resistance to environmental degradation. It is, without doubt, the most versatile of all Zippertubing's EMI shielding products and can be incorporated with almost all of our jacketing products to provide a thin, lightweight and very flexible shield. The cloth has an electrical resistance of less than 0.1 ohm/square, provides shield coverage of approximately 98% and averages 85 dB of attenuation from 10 MHz to 20 GHz. This is Zippertubing's most popular shielding material.
