Graphene Thermal Sheets for Efficient Heat Spreading

T-Global graphene thermal sheets are designed for efficient lateral heat spreading in electronic assemblies. With in-plane (XY-axis) thermal conductivity of 1500–1800 W/m·K, these ultra-thin materials help distribute heat across component and enclosure surfaces where space and weight are important design considerations.

Our graphene thermal sheets are available in 50 µm and 90 µm thicknesses. TG-P10050 and TG-P10090 combine high in-plane thermal conductivity with low mass and flexible processing options, including die-cutting into different shapes for integration into compact electronic designs.

Graphene Thermal Sheet Thicknesses and Performance

T-Global offers two graphene thermal sheet options for different mechanical and thermal design requirements:

• TG-P10050. A 50 µm ultra-thin graphene thermal sheet with 1500–1800 W/m·K in-plane thermal conductivity and 12 W/m·K through-plane thermal conductivity.
• TG-P10090. A 90 µm graphene thermal sheet with 1500–1800 W/m·K in-plane thermal conductivity and 12 W/m·K through-plane thermal conductivity.

Both materials support an operating temperature range of −20°C to +120°C and are RoHS compliant. Their thin, lightweight construction makes them suitable for applications where traditional thermal management materials may add excessive thickness or mass.

Applications of Graphene Thermal Sheets

Graphene thermal sheets can be used in electronic systems that require efficient heat spreading across limited surface areas.

AI, Servers, and Datacom Equipment

AI systems, servers, and datacom equipment can generate concentrated heat within compact assemblies. Graphene thermal sheets help spread heat laterally across available surfaces, supporting more uniform thermal distribution within space-constrained electronic designs.

5G and Telecom Electronics

5G and telecom equipment often combines high-density electronic components with limited internal space. Ultra-thin graphene thermal sheets can be integrated into these assemblies to provide heat-spreading performance without significantly increasing overall system thickness.

Automotive and Electric Vehicle Electronics

Automotive and electric vehicle electronic systems require thermal materials that can be integrated into compact assemblies. T-Global graphene thermal sheets provide lightweight heat-spreading options for electronic components, power electronics, displays, and related systems.

Consumer and High-Performance Electronics

Consumer devices, displays, AR/VR systems, industrial electronics, lighting equipment, and other high-performance electronic products can benefit from thin thermal spreading materials where component density and available space limit conventional cooling approaches.

Flexible Integration for Electronic Thermal Management

TG-P10050 and TG-P10090 can be die-cut into different shapes to match component layouts and assembly requirements. Their ultra-thin construction supports integration into applications where additional mechanical thickness must be minimized.

For applications requiring different thermal characteristics, engineers can also explore T-Global graphite thermal sheets and other thermal management materials.
