The hard felt barrel is specially designed for powder metallurgy vacuum furnaces/pressure furnaces. It has excellent thermal shock and oxidation resistance. It can work stably in a high temperature vacuum environment for a long time, greatly extending the service life of the furnace body...

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 makes...

Using PAN (polyacrylonitrile)-based carbon fiber felt and viscose-based carbon fiber felt as raw materials, the hard composite felt is made through a series of processes such as impregnation, bonding, curing, heat treatment, and machining...

Using high-quality viscose fiber, through further metal ion reduction pretreatment process, combined with needle punching structure optimization, high-quality graphite felt is produced, with high purity, good product uniformity, high temperature...

Imported high-quality viscose fiber short filaments are used to optimize the needle-punched structure, and then high-quality graphite felt is made through impregnation catalysis, pre-oxidation, carbonization and graphitization processes. Its appearance rules, thickness and width...

Impurity content is one of the key concerns in the thermal field environment of the third-generation semiconductor crystal growth furnace. In order to effectively ensure the normal growth and development of SIC crystals, the production of high-purity rubber-based carbon fiber insulation felt takes into account the protection of...

Using PAN (polyacrylonitrile)-based carbon fiber felt and viscose-based carbon fiber felt as raw materials, the hard composite felt is made through a series of processes such as impregnation, bonding, curing, heat treatment, and machining...

It is made of polyacrylonitrile fiber or viscose-based fiber as raw material and is widely used in photovoltaics, semiconductors, and high-temperature furnace heat fields.
