VeTek Semiconductor graphite soft felt has the following advantages:

1. Excellent insulation performance: It can effectively reduce heat loss, maintain a stable temperature environment inside the equipment, and reduce energy consumption.

2. Good high-temperature resistance: soft felt is able to maintain stable physical and chemical properties under high temperature conditions, and can withstand high temperature environments in photovoltaic and semiconductor production processes.

3. Low thermal conductivity: helps to achieve precise temperature control, improve process stability and product quality.

4. High chemical stability: It has good resistance to most chemical substances and is not easily corroded or contaminated.

5. High purity: reduces the interference of impurities on photovoltaic and semiconductor production processes, ensuring product performance and quality.

6. Good thermal shock resistance: able to withstand rapid temperature changes and not easily rupture or damage.

Application of VeTek Semiconductor graphite soft felt :

1. Thermal field components of single crystal furnace: In a Czochralski single crystal furnace, graphite soft felt can be used as insulation material to effectively maintain the temperature gradient inside the furnace, improve the quality and stability of crystal growth.

2. Polycrystalline ingot furnace: As a thermal insulation material, it reduces heat loss, optimizes thermal field distribution, and helps improve the quality and production efficiency of polycrystalline silicon ingots.

3. Diffusion furnace: used for insulation, ensuring temperature uniformity inside the furnace, and improving the accuracy and consistency of diffusion processes.

4. Epitaxial furnace: provides a stable thermal environment for the epitaxial growth process, reducing the impact of temperature fluctuations on the quality of semiconductor epitaxial layers.

5. Semiconductor packaging: In some high-end semiconductor packaging processes, it plays a role in insulation, buffering, and support, protecting chips from thermal and mechanical stress damage.

6. Photovoltaic cell manufacturing equipment: such as plasma enhanced chemical vapor deposition (PECVD) equipment, used to maintain temperature stability inside the equipment and ensure the quality of thin film deposition.

VeTek Semiconductor graphite soft felt including:

Rayon-based carbon/graphite felt It has properties such as high temperature resistance, corrosion resistance, high purity, low ash content, and no oil pollution. Small wire diameter, strong insulation performance. Mainly used in single crystal growth furnaces and high-end high-temperature equipment.
Pitch-based carbon/graphite felt Using German original silk weaving, its corrosion resistance, oxidation resistance, and purity are superior to Rayon-based materials, and it has better insulation performance. Mainly used in high-performance equipment in the photovoltaic single crystal industry.
PAN carbon/graphite felt It has properties such as high temperature resistance, corrosion resistance, high purity, low ash content, light and soft texture, and high shape retention. In high-temperature environments protected by vacuum or inert gas, its insulation performance is superior and stable. Widely used in high-temperature equipment such as single crystal growth furnaces, polycrystalline ingot furnaces, and medium frequency induction furnaces.
Pre oxidized graphite felt Through strict screening of high-quality raw materials and continuous improvement of production processes, a product with insulation performance similar to rayon-based graphite felt and a lifespan better than PAN based graphite felt has been obtained; It has the characteristics of good insulation, erosion resistance, high purity, low ash content, high strength, and long service life, and has an ultra-high cost performance ratio. It is widely used in single crystal growth furnaces, polycrystalline ingot furnaces, and medium-frequency induction high-temperature furnaces, and graphite resistance high-temperature furnaces."
Battery felt Made from high-quality German-imported PAN-based fibers, it boasts exceptional performance in parameters such as flatness, porosity, density, specific surface area, and conductivity. It is primarily used in applications such as fuel cells and flow batteries.
