Rigid Graphite Felt – Thermal Insulation Materials for Industrial Furnaces

Description

Rigid graphite felt has excellent ablative resistance, thermal shock resistance, airflow erosion resistance, good high temperature insulation effect and high temperature stability, etc. It is widely used in most high-end markets, including solar energy industry, semiconductor monocrystalline silicon industry, artificial crystal industry, optical fiber industry, high temperature vacuum sintering furnaces, heat treatment furnace, etc.

Rigid graphite felt is a thermal insulation material that is based on soft graphite felt and then formed by using a small amount of binder to composite any shape (for example, barrel, disk, cuboid) after high-temperature graphitization treatment. It can effectively improvs the original working environment and operability. Besides, it can also have different surface coating treatments upon request to meet the needs of various applications. Compared with soft felt, its fume forming rate is significantly reduced, thereby extending its service life.

Rigid graphite felt is generally divided into pitch-based rigid graphite felt, PAN-based rigid graphite felt and rayon-based rigid graphite felt.In addition to rigid felt based on soft graphite felt, we also have a new type of rigid graphite felt made from a laminated material composed of fiber filaments and binder, which is then graphitized at high temperatures to form a complete felt.

In addition, we provide comprehensive vacuum furnace hot zone maintenance solutions, including graphite groove plate, rigid graphite felt, soft graphite felt, carbon-carbon composites and other high performance parts to ensure efficient and reliable equipment operation under high temperature environments.
