Flexible Graphite Foil

Semicorex Flexible Graphite Foil is a cutting-edge material derived from natural graphite flakes. Through a meticulous process involving chemical preparation with acids and oxidizing agents, the natural graphite undergoes an intense heat treatment that expands its structure. This results in self-bonded graphite particles that form a continuous, flexible strip without the need for additional binders. The outcome is a low-density, high-performance material available in rolled sheets, making it ideal for a variety of applications.

Exceptional Properties

Flexible Graphite Foil boasts a remarkable array of properties that make it a preferred choice for sealing and gasket applications. Here are some key features:

1. Chemical Resistance: It exhibits excellent resistance to a wide range of chemical agents, ensuring longevity and reliability in harsh environments.
2. Stability Over Time: The material remains unaffected by environmental changes, providing consistent performance without material alteration over time。
3. Wide Temperature Range: Flexible Graphite Foil can endure extreme temperatures ranging from -196 °C to 2,500 °C in inert atmospheres, and up to 450 °C/550 °C in air. This resilience makes it suitable for various industrial applications where temperature fluctuations are common.
4. High Compressibility: The foil's unique structure allows for high compressibility, ensuring effective sealing under pressure.
5. Elastic Recovery and Low Creep: Its exceptional elastic recovery and notably low creep within its working temperature range guarantee a proper seal, making it indispensable for applications requiring reliability and precision.

6. Ease of Transformation: The material is easy to cut and manipulate, allowing for the creation of flat seals tailored to specific requirements.
