PAN based Carbon Fiber

Semicorex PAN Based Carbon Fiber Graphite Soft Felt is an advanced insulation material designed for use in high-temperature environments. It is crafted through a meticulous production process that begins with precursor fibers such as polyacrylonitrile (PAN) and viscose. These fibers are first formed into a felt structure using a nonwoven process. For viscose-based materials, an impregnation step is incorporated to enhance performance. This is followed by pre-oxidation, carbonization, graphitization, and precise cutting to produce the final product. Each step is carefully controlled to ensure the material achieves the highest standards of quality and performance.

One of the most notable characteristics of this soft felt is its exceptionally low density, approximately 0.10 g/cm³. This makes it nearly one-tenth the density of water. Such a lightweight structure is achieved by combining the intrinsic properties of the graphite fibers, which are thin and light, with the microvoids formed between the interwoven fibers. The result is a material that is not only light but also highly efficient in thermal insulation, a key requirement for high-temperature industrial applications.

The thermal conductivity of the material is another critical feature. At 1150°C, it measures just 0.10–0.15 W/m·k, which is remarkably low. This minimal thermal conductivity ensures excellent insulation performance, allowing the material to retain heat effectively and reduce energy loss in high-temperature processes. The lower the thermal conductivity, the better the insulation capability, making this product an ideal solution for demanding thermal applications.

In addition to its insulation properties, the soft felt is highly pure, thanks to the advanced graphitization process. This purity ensures that it does not introduce contaminants into sensitive processes, making it suitable for applications requiring clean and controlled environments. Furthermore, the material’s inherent flexibility allows it to be tailored to specific dimensions and shapes, offering great adaptability for use in various industrial settings.

The applications of PAN Based Carbon Fiber Graphite Soft Felt are extensive. It is widely utilized in vacuum furnaces, where efficient thermal insulation is essential to maintain stable conditions. The material also plays a critical role in crystal growth furnaces used for manufacturing silicon and silicon carbide crystals, processes that demand precise thermal management to achieve high-quality results. In powder metallurgy, the soft felt provides insulation in furnaces, ensuring uniform temperature distribution and protecting materials and equipment from thermal shocks. Additionally, it is used in sintering and heat treatment equipment, where its lightweight and high-temperature resistance make it a preferred choice for insulation.

Compared to alternative insulation materials, PAN Based Carbon Fiber Graphite Soft Felt offers significant advantages. Its superior insulation efficiency translates to reduced energy consumption and lower operating costs. The material is also highly durable, maintaining its integrity even in extreme thermal conditions, which ensures a longer service life and minimizes the need for frequent replacements. Its high purity and stability make it particularly suitable for sensitive applications, reducing the risk of contamination and maintaining process quality. Moreover, its lightweight and flexible nature simplify handling and installation, even in complex or confined spaces, enhancing its usability.
