Carbon fiber hard composite felt (warm synthetic integral felt)
Product description:
Carbon fiber hard composite mat (mixed-molded integral mat) is a carbon fiber reinforced carbon-based composite material made by mixing and pressing chopped carbon fibers with resin. Due to its unique structure, it has attracted widespread attention in the field of third-generation semiconductors and is mainly used in high-end thermal field environments such as semiconductor crystal growth furnaces and epitaxial furnaces.
Product features:
- High relative mechanical strength
- Good density uniformity
- High purity, low ash
- Good processability
- Excellent thermal insulation performance
- High temperature oxidation and erosion resistance
