Nickel-Graphite Tubing: EMI
Achieving both airtight sealing and Electromagnetic Interference (EMI) shielding is a primary challenge in telecom enclosures. Nickel-Graphite Conductive Silicone Tubing, featuring a hollow extrusion design and high-conductivity fillers, provides exceptional elastic compensation and ultra-low grounding resistance after compression.
Physical Principles: Percolation Networks and Impedance Models The effectiveness of Nickel-Graphite Conductive Silicone Tubing tubing relies on the precise distribution of nickel-coated graphite particles:
Filler Synergy: Nickel provides superior conductivity and corrosion resistance, while the graphite core reduces weight and enhances matrix affinity.
Volume Resistivity (ρ) and Compression: Resistance decreases as the pressing force increases. The model is: R = ρ × (L / A) (Resistance = Volume Resistivity × Length / Compressed Area) Lixing maintains ρ < 0.05 ohm-cm, ensuring shielding effectiveness > 100 dB.
Compression Set Resistance: The high-grade silicone base ensures stable rebound stress under long-term load, eliminating interface voids and preventing EM leakage.
Industrial Applications: Telecom Cabinets and Outdoor Base Stations Lixing Composite Material offers conductive tubing with precise CFD and aging data:
Outdoor 5G Systems: Excellent salt spray resistance ensures consistent shielding in high-humidity environments.
Rework Efficiency: High tear strength prevents powdering or structural failure after repeated maintenance openings, meeting zero-residue standards.
