This SiC substrate company secured hundreds of millions in Series D funding, with the third-generation semiconductor materials market on the verge of explosion!

SGL GFA soft felt is a flexible insulating material characterized by its light weight, good flexibility, high carbon content, high-temperature resistance, no volatilization at high temperatures, corrosion resistance, low thermal conductivity, and high shape retention. It is suitable for high-temperature vacuum resistance furnaces, particularly for high-temperature applications in inert or vacuum environments, and is entirely composed of carbon fibers.

Summary of its typical material properties:

Very low thermal conductivity at maximum temperatures

Low heat capacity

Suitable for very high temperatures

Pure carbon fiber

SGL MFA hard felt is a rigid insulating material based on carbon fibers with low thermal conductivity. It exhibits excellent performance in inert gas or vacuum furnaces at temperatures exceeding 800°C, with shape stability, thermal shock resistance, and erosion resistance.

Summary of its typical material properties:

Stable

Low thermal conductivity

Thermal shock resistance

Corrosion resistance

Our company long-term supplies SGL high-purity GFA soft felt and MFA hard felt, and can customize according to different customer needs.
