The tape consisting a copper foil backing coated with acrylic pressure sensitive adhesive.copper tape has a conductive acrylic adhesive for grounding and RFI/EMI (radio-frequency interference/electromagnetic interference) shielding applications. Also known as EMI shielding tape, it provides a very low rate of electrical resistance for good conductivity. The tape is solderable, resists oxidation and discoloring, and withstands temperatures up to 120 degrees . It has a peel-off liner, which protects the adhesive from exposure to air until ready for use.Copper Foil Tape with Conductive Adhesive are also known as EMI Shielding Tape or RFI Shielding Tapes. They are made from thin copper foil with an acrylic conductive adhesive. These copper foil tapes are packaged on a paper liner on a 3 inch core for easy handling and cutting. The Copper Foil tapes provide a very low rate of electrical resistance and come with a conductive adhesive. The Bapna Copper Foil Tapes can also be used for building ground systems, static charge draining, cable wrapping and, surface contact to non-solderable material and point to point electrical contact. The Copper Foil Tapes are also RoHS & REACH Compliant. The Bapna Copper Foil Tapes can be used for many applications: ELECTRICAL REPAIRS: Bapna Copper Foil Tapes have high conductivity and low resistance which make them great for any electrical or do it yourself repairs. A great use for the Bapna Copper Foil Tape can be used to shield speaker wire from interference. Wrap the tape around wires that are too close together to stop a hum or buzz coming through your speaker system.
