Pitch-based carbon fiber net felt is an advanced material engineered for applications requiring optimized thermal stability, superior electrical conductivity, and enhanced structural integrity. Manufactured through controlled carbonization and fiber processing, this net felt provides excellent flexibility, durability, and high porosity, making it suitable for thermal insulation, energy storage, filtration, and composite reinforcement applications.
Product Overview
Pitch-based carbon fiber net felt is a net-like material made from pitch-based carbon fibers processed through fine manufacturing techniques. This material, which uses aromatic hydrocarbons-rich substances (such as pitch) as raw materials, undergoes spinning, pre-oxidation, and carbonization processes. It is available in general-grade and high-performance-grade carbon fibers. The key features of this material include low density, high strength, high-temperature resistance, ablation resistance, chemical corrosion resistance, and a low coefficient of thermal expansion. It is widely used in the photovoltaic and semiconductor industries, particularly for monocrystalline and polycrystalline silicon furnaces, as well as high-temperature vacuum furnaces, serving as excellent insulation and heat-resistant material.
