As consumer demand for thinner and lighter electronic devices continues to grow, products such as smartphones, laptops, and smart wearables (AR/VR) are moving toward higher levels of integration. While device sizes shrink, they must accommodate more functions, placing greater demands on circuit design compactness — which in turn increases the risk of electromagnetic interference (EMI). EMI can not only cause signal distortion, delay, or loss, but prolonged exposure to electromagnetic interference can also accelerate the aging of electronic components and even lead to permanent damage.
To address the growing challenge of electromagnetic interference (EMI) in consumer electronic devices, conductive tapes have emerged as an effective solution. They provide reliable EMI shielding and grounding functions, and can be flexibly applied in the later stages of design without requiring complex modifications to existing electrical systems.
CROWN New Materials’ EM Series conductive tapes combine multiple filler materials to deliver excellent conductivity and electromagnetic shielding performance, reducing EMI and ensuring stable device operation. They also feature anti-warping properties, enabling secure adhesion even on curved surfaces.
Applications:
- Electromagnetic shielding
- Grounding and conductive bonding
- Conductive foam wrapping
- CROWN New Materials EM Series — Substrate-Free Conductive Tape
- Formulated with modified acrylic adhesive, this tape delivers excellent bonding strength and conductivity. Paired with low surface resistance materials, it achieves effective EMI shielding. Suitable for bonding conductive fabrics, conductive foam, conductive nonwoven fabrics, copper foil, aluminum foil, and other conductive substrates, it is primarily used for EMI shielding, conductive bonding, and static discharge.
- CROWN New Materials EM Series — Woven Fabric Conductive Tape
- With low impedance, high conductivity, and excellent flexibility, this tape is ideal for conductive bonding and component fixing in smartphones, tablets, and other devices, and can also be used as a spacer.
- CROWN New Materials EM Series — Nonwoven Fabric Conductive Tape
- Anti-warping, lightweight, soft, and highly durable, this tape offers clean die-cutting without fiber fraying. It is suitable for both flat and irregular surfaces, adheres easily to curved surfaces, and is used in ferroelectric devices for bonding electrode plates to magnet crystals.
- CROWN New Materials EM Series — Aluminum Foil Conductive Tape
- Provides excellent static discharge performance after grounding. Applications include shielding and grounding components in smartphones, connecting fine wires to printed circuits, electroplated base plates, and ceramic substrates with metal layers or chassis; bonding wires to sockets; and attaching components to through-holes on printed circuits.
CROWN New Materials’ conductive tapes have been successfully applied in the consumer electronics industry, driving innovation and development. Beyond conductive tapes, the EM Series also offers advanced solutions for shielding and absorption in complex electromagnetic environments. Among them, wave-absorbing materials, as an important functional category, are widely used to address EMI and EMC issues. The company is actively advancing testing and validation of related products to deliver more reliable and efficient solutions to the industry.
