Graphite Foil Roll

High-Temperature Resistance

Our Graphite Foil Roll is renowned for its exceptional high-temperature resistance. It can withstand temperatures up to 510°C in an oxidizing atmosphere and 850°C in steam. In a vacuum or reducing environment, its resilience extends to an impressive 3000°C. Furthermore, it retains its structural integrity at low temperatures, down to -200°C. This vast range of thermal tolerance makes it an ideal choice for applications where stability and performance at extreme temperatures are critical.

Minimal Weight Loss in Harsh Conditions

One of the standout features of the Graphite Foil Roll is its minimal weight loss in high-temperature environments. This characteristic is particularly crucial for long-term sealing applications, where performance degradation can lead to system failures. Semicorex’s Graphite Foil Roll has been tested to show a remarkably low weight loss rate of just 2% per hour under TGA tests at 670°C in the air, a stark contrast to conventional foils which can lose up to 40%. This low weight loss rate ensures longevity and reliability in demanding applications.

Ultra-Low Ash Content

The Graphite Foil Roll contains less than 0.15% ash, meeting the stringent requirements of high-purity applications. This low ash content is essential in processes where contamination can be a significant issue, such as in the semiconductor, solar, and ceramic industries. By minimizing impurities, Semicorex ensures that the Graphite Foil Roll delivers consistent, high-quality performance.

Chemical Inertness and Broad pH Range Compatibility

In addition to its thermal properties, the Graphite Foil Roll is chemically inert, making it resistant to most fluids across a wide pH range of 0 to 14. This includes acids and bases, though it should be noted that strong oxidizers like nitric or sulfuric acid might affect it. This chemical resistance makes it versatile for use in various environments, including those involving aggressive chemicals.

Anisotropic Electrical and Thermal Conductivity

Another notable property of the Graphite Foil Roll is its highly anisotropic nature. The electrical and thermal conductivity characteristics vary significantly in the direction parallel to and perpendicular to the graphite flakes. This makes it suitable for applications where directional conductivity is advantageous. The anisotropic properties can be leveraged in specialized thermal management and electrical applications, providing tailored solutions for complex engineering challenges.

Self-Lubricating with Low Friction Coefficient

Graphite Foil Roll’s low coefficient of friction and self-lubricating properties contribute to its efficiency in dynamic applications. This self-lubricating feature reduces wear and tear, extending the lifespan of components and systems where it is employed. It is particularly beneficial in sealing applications where consistent performance and durability are required.

Outstanding Oxidation Resistance

The unique structure of the Graphite Foil Roll provides remarkable oxidation resistance. This is a critical feature for maintaining the material’s integrity and performance over extended periods in oxidizing environments. The low oxidation rate ensures that the Graphite Foil Roll remains effective even under prolonged exposure to high temperatures, thereby maintaining its sealing and insulating properties.
