VeTek Semiconductor is a company that specializes in manufacturing advanced semiconductor materials, including SiC coatings, tantalum carbide coatings, and high-purity carbon fiber. Our company has achieved numerous technological breakthroughs and holds several technology patents. The carbon fiber materials offered by VeTek Semiconductor, such as C/C composites, rigid felt, and soft felt, are widely used in the semiconductor thermal field. The main advantages are as follows:

VeTek Semiconductor's carbon-carbon composites are the ideal solution for photovoltaic and semiconductor pulling applications. These composites are made of high-quality carbon fibers and a carbon matrix, providing excellent mechanical strength, thermal stability, and high-temperature resistance of up to 3000℃. They exhibit exceptional resistance to thermal shocks, low thermal expansion, and high thermal conductivity, making them ideal for applications that require high precision and stability.

VeTek Semiconductor's graphite felt insulation material is a high-performance solution for high-temperature applications. It is made of high-purity carbon fibers and exhibits excellent heat resistance, thermal stability, and insulation properties. Our graphite felt has a low thermal conductivity and can withstand temperatures of up to 2200°C. It is widely used in various industrial applications such as semiconductor furnace insulation, thermal shields, and fire protection systems. Additionally, our graphite felt insulation material is lightweight, flexible, and easy to handle, making it an ideal choice for insulating complex shapes and confined spaces.
