Waterproof Linerless Foil Tape for EMI & Heat Shielding
-- Steady & Reliable Manufacturer --
Multi-Functional Shielding and Sealing Tape with Efficiency Focus
This highly technical tape combines three critical functions—EMI Shielding, Heat Shielding/Reflection, and Waterproof Sealing—into an efficient linerless format. The product features an electrically conductive aluminum foil backing and a specialized high-performance adhesive system. The linerless design optimizes application speed, while the conductive foil ensures effective EMI/RFI suppression and static dissipation in electronic assemblies. The aluminum backing provides simultaneous heat reflection and forms a robust, waterproof seal against moisture ingress. This unique combination makes it a versatile, high-value component for electronic devices and assemblies exposed to environmental factors or requiring streamlined production.
- Triple Functionality: EMI shielding, heat reflection, and moisture barrier in one product.
- Linerless Efficiency: Faster application with zero liner waste.
- Electrical Conductivity: Ensures a reliable grounding path for sensitive components.
Why Choose Us
Integrated Technical Superiority and Process Optimization
- Verified Electrical Continuity: The adhesive system is either inherently conductive or formulated to ensure metal-to-metal continuity across the overlapping sections, providing a reliable, low-resistance path for grounding the shield.
- Extreme Waterproofing: The barrier properties are maintained even in the absence of a liner. The aggressive acrylic adhesive resists water and moisture intrusion at the bond line, protecting the electronics from environmental failure.
- Streamlined Assembly Process: The linerless design facilitates easy dispensing and cutting in fast-paced production environments, enabling the assembly line to achieve high output rates for multi-functional requirements.
- Minimized Material Footprint: By combining three critical functions into a single, thin material, this tape reduces the total bill of materials (BOM) complexity and inventory required for assembly.
Core Features
Integrated Shielding and Sealing Applications
- External Electronics Enclosures: Sealing seams and ports on outdoor or ruggedized electronic enclosures (e.g., 5G base stations, surveillance cameras) where environmental protection and EMI integrity are required.
- Cooling System Assembly: Fixing and sealing heat sinks to processors while simultaneously providing an EMI-safe grounding path.
- Appliance Control Panels: Shielding internal wires and circuit boards from external interference and providing a waterproof seal to the housing.
- Automotive Sensor Housings: Sealing and providing thermal/EMI shielding for sensors and control units exposed to engine heat and road spray.

Frequently Asked Questions
Frequently Asked Questions (FAQ)
- Q: What is the typical shielding effectiveness (dB) of this tape?
- A: The shielding effectiveness is generally high, often ranging from 60 dB to 80 dB across typical electronic operating frequencies, depending on the overlap and grounding integrity. Full test data is provided upon request.
- Q: How does the linerless feature affect the conductivity of the adhesive?
- A: The linerless feature is achieved through a backing treatment and does not interfere with the conductive properties of the adhesive (if applicable). If the adhesive is non-conductive, the tape relies on the foil-to-foil overlap to ensure conductivity.
- Q: Can this tape be used for long-term outdoor exposure where UV light is intense?
- A: Yes. The aluminum foil backing is highly UV-resistant and inert, ensuring the shielding and waterproof barrier integrity is maintained even after prolonged sun exposure, making it suitable for protected outdoor enclosure applications.
