High Purity Graphite Sheet

High Purity Graphite Sheet or paper is produced by chemically treating and high-temperature expanding high-carbon flake graphite. This new material serves as the foundational material for manufacturing various graphite seals. Graphite paper possesses excellent thermal conductivity, but the thermal conductivity of different graphite paper products can vary due to differences in manufacturing processes and raw materials. Additionally, various factors can influence the thermal conductivity of graphite paper.VeTek Semiconductor high purity graphite sheet is stable over a wide temperature range (-200℃~3200℃ inert atmosphere).

Characteristics of Graphite Paper

1. Thermal Stability: Specially designed for conditions of rapid heating and cooling to ensure product quality reliability.

2. Corrosion Resistance: A uniformly dense matrix design delays the degree of corrosion.

3. Impact Resistance: Graphite can withstand extremely high thermal shock strength, ensuring safe processing.

4. Acid Resistance: The addition of special materials significantly improves acid resistance, extending its service life.

5. High Thermal Conductivity: A high fixed carbon content ensures excellent thermal conductivity, shortens melting time, and significantly reduces energy consumption.

6. Metal Contamination Control: Strict control of material composition ensures that graphite paper does not contaminate metals during the melting process.

7. Quality Stability: The production technology of high-pressure forming and the quality assurance system ensure the stability of the product.

With the rapid upgrade of electronic products and the growing demand for thermal management in miniaturized, highly integrated, and high-performance electronic devices, new graphite material cooling solutions have emerged. Graphite paper, with its efficient heat dissipation, compact size, and light weight, has become an ideal choice. It can conduct heat evenly in two directions, eliminate "hot spots," and shield heat sources from components, significantly improving the performance of consumer electronics.

High-purity graphite paper, with its outstanding performance, shows broad application prospects in various industries. It not only performs excellently in traditional industrial fields but also provides innovative solutions for the thermal management of modern electronic products.
