Key Features
EMI / EMC shielding for EV electronics
The copper foil tape, coated with an electrically conductive, pressure sensitive acrylic adhesive, is used for EMI/EMC shielding. It is specially designed for EV application, with a thickness of 65–70 micron. It passes the 2 point test method and bear temperature range of T2.
Manufactured under an ISO 9001:2015-certified quality management system.
Copper Foil Tape from Mr.Bond® is a copper foil backing coated with an electrically conductive, pressure-sensitive acrylic adhesive, used for EMI and EMC shielding. It is specially designed for EV applications and is supplied at a thickness of 65 to 70 microns. The tape passes the 2-point test method and bears a temperature range of T2. Because the adhesive itself conducts, the joint between overlapping strips of foil conducts too, so a wrapped harness, enclosure seam or cable shield behaves as one continuous shield rather than as separate patches. Typical users are EV electronics and battery pack builders who need to contain electromagnetic interference around inverters, control boards and wiring. Copper Foil Tape is manufactured by Lalit Jain Industries Pvt. Ltd. (LJIPL), an ISO 9001:2015 certified tape manufacturer founded in 1987, from its units at Rai, Sonipat (Haryana) and Bawana, Delhi NCR, India. Share your width and roll length requirement for a quote.
Copper foil tape is used for EMI / EMC shielding. EMI is electromagnetic interference, unwanted electrical noise radiated by one circuit that upsets another. EMC is the discipline of making sure equipment neither emits too much of it nor is disturbed by it. A conductive foil wrapped around a cable, seam or enclosure gives that noise a path to follow instead of letting it radiate.
The Mr.Bond® product is coated with an electrically conductive, pressure-sensitive acrylic adhesive, which is the important detail. With a conductive adhesive, overlapping strips of foil are electrically joined through the glue line, so the shield stays continuous across a seam.
It is specially designed for EV application, at 65 to 70 micron thickness, and it passes the 2-point test method and bears a temperature range of T2. It is typically ordered with insulation materials from the wider group range at Lalit Jain Industries Pvt. Ltd. (LJIPL).
An ordinary acrylic adhesive is an insulator. If you shield with a foil tape that has a non-conductive adhesive, every overlap becomes an electrical break in the shield, and the shield is only as good as its worst joint.
The conductive, pressure-sensitive acrylic adhesive on this tape removes that break. Current can pass through the adhesive from one layer of foil to the next, so a spiral wrap on a harness or a taped seam on an enclosure works as a single shield.
Pressure-sensitive means the tape needs only firm hand or roller pressure to bond, no heat, no solvent, no curing time on the line. The corollary matters on a shielding job: a conductive adhesive pressed lightly onto an oxidised or anodised surface gives a poor electrical joint while looking well stuck, which is covered along with the rest of the specification checklist in copper foil tape for EMI shielding and grounding.
65 to 70 microns is the quoted thickness of the tape. A micron is one thousandth of a millimetre, so this is a thin, conformable foil that can be wrapped around cable bundles and pressed into corners without fighting back.
The tape passes the 2-point test method and bears a temperature range of T2, the two qualification figures quoted for this grade. When you enquire, send the substrate, the width and the temperature your assembly reaches so the right grade is confirmed for you.
Shielding is one of five jobs tape does inside a battery pack; the EV battery tapes hub sets out the others and the material used for each.
Power electronics in an electric vehicle switch hard and fast, and the noise they radiate has to be contained. This tape is specially designed for EV application and is used to shield enclosures and seams, with a conductive adhesive so overlapping strips stay electrically joined.
At 65 to 70 microns the foil is thin enough to wrap tight corners and to overlap itself neatly. Because the pressure-sensitive acrylic adhesive conducts, each overlap carries current rather than interrupting the shield, which is what makes a taped shield behave as one piece.
Pressure-sensitive application suits production work: position the foil, press it down, move on. No heat or curing step is needed. The tape passes the 2-point test method and bears a temperature range of T2, so it is qualified for continued use rather than temporary patching.
It is used for EMI and EMC shielding, wrapping cables, seams and enclosures in a conductive copper layer so electromagnetic interference is contained rather than radiated. This grade is specially designed for EV application and is coated with an electrically conductive, pressure-sensitive acrylic adhesive so overlapping strips remain electrically connected.
It is supplied at a thickness of 65 to 70 microns. A micron is one thousandth of a millimetre, so the foil is thin and conformable, which is what allows it to be wrapped around cable bundles and pressed into corners and seams without lifting at the edges.
Yes. The tape is coated with an electrically conductive, pressure-sensitive acrylic adhesive. That is essential for shielding work, because it lets current pass through the glue line where two layers of foil overlap, keeping the shield continuous instead of leaving an electrical break at every joint.
Yes. This grade is specially designed for EV application. It passes the 2-point test method and bears a temperature range of T2, and it is used for EMI / EMC shielding in electric vehicle electronics and battery pack work alongside the other Mr.Bond® insulation and thermal materials.
EMI stands for electromagnetic interference, the electrical noise one circuit radiates into another. EMC, electromagnetic compatibility, is the requirement that equipment neither emits excessive interference nor is upset by it. A conductive copper layer around a cable or enclosure gives that noise a controlled path and is one of the standard ways of meeting the requirement.
It is made by Lalit Jain Industries Pvt. Ltd. (LJIPL), an ISO 9001:2015 certified adhesive tape manufacturer founded in 1987 and led by directors Mr. Prateek Jain and Mr. Shikhar Jain. Production runs from two units, at Rai, Sonipat in Haryana and Bawana in Delhi, India.
