Aohong Conductive Graphite Mesh Sheets: The Smart Thermal Interface Material

Walk into any modern electronics lab in Shenzhen and you’ll see engineers working with our graphite-embedded wire mesh sheets – what industry professionals call “thermal bridging composites.” These innovative materials combine the best properties of expanded graphite and stainless steel mesh, creating what we at Aohong have trademarked as “ThermaGrid” technology.

Technical Advantages That Matter

• Thermal conductivity: 400-450 W/mK in-plane (x-y axis)
• Compressive strength: 1.2-1.8 MPa (30% better than standard graphite)
• Operating temperature: -200°C to 450°C continuous
• EMI shielding effectiveness: 60-80 dB across 1-10 GHz range

Why OEMs Choose Our Solution

1. Prevent Hot Spotsin 5G base stations using our patented z-axis heat spreading
2. Reduce Component Failurein EV battery packs with vibration-resistant design
3. Simplify Assemblythrough pre-applied adhesive options (available in 3M™ or Dow Corning® formulations)

The Aohong DifferenceOur graphite mesh sheets outperform competitors in three key areas:

1. Consistency– Batch-to-batch thermal variance <5%
2. Durability– 100,000 flex cycles without cracking
3. Support– Local technical teams in 12 countries

With the rising demand for compact thermal solutions in IoT devices, our conductive graphite mesh sheets are becoming the go-to choice for engineers who need reliable heat dissipation without adding unnecessary weight or complexity.
