Core Value and Product Advantages
- Excellent In‑Plane Thermal Conductivity and Temperature Uniformity
Leveraging the highly oriented crystal structure of graphite, the sheet achieves very high in‑plane thermal conductivity (up to 300–1500 W/(m·K)), rapidly spreading heat across the plane to eliminate local hotspots and enable efficient temperature equalization. This makes it an outstanding thermal interface material between chips and housings. - Good Flexibility and Compressive Resilience
The material is soft and pliable—it can be bent, wound, or stamped into complex shapes and can fill uneven interface gaps. Under certain compressive stress, it maintains good resilience, providing long‑term sealing contact force suitable for both dynamic and static sealing applications. - Outstanding Chemical and Thermal Stability
Inheriting graphite’s intrinsic properties, it operates stably across a wide temperature range from –200°C to 3000°C (in non‑oxidizing atmospheres) and resists corrosion from most acids, alkalis, and organic solvents, making it suitable for harsh operating conditions. - Multi‑Functional Lamination and Precision Processing
Beyond standard rolls and sheets, we offer advanced processing to meet integrated requirements:- Adhesive‑Back Lamination: Single‑ or double‑sided lamination with pressure‑sensitive adhesive (PSA), silicone, etc., for easy installation.
- Metal‑Composite Lamination: Combined with copper or aluminum foils to enhance mechanical strength or modify electromagnetic shielding performance.
- Precision Die‑Cutting: High‑precision punching, die‑cutting, and slitting based on your mounting‑surface drawings, providing custom shapes ready for immediate application.
- Surface Coatings: Special treatments such as oxidation‑resistant coatings.
Primary Application Scenarios
- Electronics Thermal Management
Used as thermal pads between CPUs/GPUs, power devices, LED modules and heat sinks/housings to fill gaps and efficiently transfer heat. - High‑Temperature Sealing and Gaskets
Applied as static sealing gaskets for engine cylinder heads, chemical‑pipeline flanges, high‑temperature valves, and vacuum‑furnace viewports—resistant to high temperatures and corrosion. - Fuel Cells and Energy Systems
Serves as a core substrate for gas diffusion layers (GDL) in proton‑exchange‑membrane fuel cells (PEMFC) or as sealing gaskets for solid‑oxide fuel cells (SOFC). - Industrial Heating and Insulation
Used as flexible insulation layers in high‑temperature furnaces, shielding layers for induction heating, or as base materials for heating elements.
