Key advantages – engineered for EMI/RFI protection
🛡️
Four filler materials – precision-matched to your shielding requirements
From 130dB military-grade to >45dB industrial
Our conductive silicone EMI shielding strip is available in four distinct filler materials: Ag/Al delivers 130dB shielding with the best mechanical properties – ideal for military and medical applications; Ag offers the highest conductivity for telecom; Ni/C provides cost-effective 110dB shielding for industrial enclosures; Conductive Fabric Foam delivers<4Ω/inch surface resistance and UL94 V-0 flame rating – perfect for EV battery packs and large-tolerance applications. Surface resistance ranges from<4Ω/inch to <50Ω/inch, ensuring consistent electrical continuity.
→ The right material for your application
🔒
Low compression set – shielding that stays reliable
Conductive fabric foam<5% · Ag/Al/Ag/Ni/C ~9% (100°C/168h)
After millions of compression cycles and high-temperature aging, our silicone shielding strips maintain their shape and shielding effectiveness. Conductive fabric foam achieves <5% compression set; Ag/Al, Ag, and Ni/C achieve ~9%. Resistance remains stable after 100°C aging – preventing shielding failures caused by permanent deformation. Reduces warranty claims and field failures.
→ Long-term reliability · reduced maintenance
🌡️
Wide temperature range & salt spray resistance
-55°C to +160°C · coastal and outdoor ready
Our conductive EMI gasket performs reliably across a -55°C to +160°C temperature range. Salt spray resistant – suitable for coastal base stations, outdoor enclosures, and harsh environments including desert, arctic, and marine conditions. Proven in 5G base stations, EV battery packs, and outdoor cabinets.
→ Any climate · any environment
🏗️
Integrated shielding + sealing – one component, one installation
EMI/RFI protection + environmental sealing
Unlike conventional rubber seals that provide only environmental protection, or metal shields that cannot conform to complex geometries, our conductive silicone rubber strip combines both in a single component. Shielding effectiveness from >45dB to 130dB – blocks up to 99.9999% of electromagnetic emissions. One component, one installation step, one quality standard – reduced cost, simplified assembly, improved reliability.
→ Simpler assembly · lower cost
📐

Frequently asked questions – for EMI shielding buyers
What is the difference between Ag/Al, Ag, Ni/C, and conductive fabric foam?
Ag/Al offers the highest shielding (130dB) and best mechanical properties – ideal for military and medical. Ag offers highest conductivity – ideal for telecom. Ni/C offers best cost-performance – ideal for industrial. Conductive fabric foam offers lowest surface resistance (<4Ω/inch) and UL94 V-0 – ideal for battery packs and large-tolerance applications.
What does 130dB shielding effectiveness mean?
100dB = 99.999% electromagnetic wave shielding. 130dB = 99.9999%+ shielding. Ag/Al and Ag meet the most stringent military, aerospace, and high-end medical requirements.
Does the product meet military standards?
Yes. Our conductive silicone shielding strips are tested per MIL-G-83528 and ASTM D412 standards. Full test reports are available upon request.
What is the recommended compression for installation?
Recommended compression: 15% to 40% of original height. Maximum: 50%. Excessive compression may cause permanent deformation and reduce shielding effectiveness.
Do you offer adhesive backing and cutting services?
Yes. We offer 3M conductive adhesive backing, cutting to specified length, and complete kit supply. Custom packaging available.
What is the shelf life and storage requirement?
Sealed storage, protect from direct sunlight, avoid prolonged air exposure. Under dark, room temperature conditions: 1-year shelf life. We recommend just-in-time procurement.
What is the lead time for custom orders?
Samples: 3-5 days for standard profiles, 7-10 days for custom. Production: 5-7 days after sample approval. Expedited service available.
Can I get free samples and certification documentation?
Yes. We provide free samples of standard sizes for qualified buyers, along with COA test reports, MIL-G-83528 compliance documentation, and RoHS/REACH certificates.
