Why Conductive Graphite Sheets Are Essential for Modern Thermal Management
Conductive graphite sheets have emerged as critical components in electronics, automotive, and aerospace industries due to their exceptional thermal conductivity (up to 1,500 W/m·K) and electrical resistance below 5 μΩ·cm. These sheets dissipate heat 40% more efficiently than traditional aluminum alloys while maintaining flexibility as thin as 0.1 mm. Global demand is projected to grow at 8.7% CAGR through 2030, driven by 5G infrastructure and electric vehicle adoption.
Superior Performance Metrics in Thermal Materials
Key technical differentiators include:
- Anisotropic thermal conductivity: 1,200-1,800 W/m·K in-plane vs. 10-20 W/m·K through-plane
- Compressive strength exceeding 50 MPa at 0.2 mm thickness
- Long-term stability across -200°C to 400°C operational ranges
