Hard composite carbon fiber felt(High purity product)

Short Description:

Hard composite carbon fiber felt is processed by special technology of solidification and setting, and secondary high-temperature purification treatment with graphite foil, polyacrylonitrile base carbon felt and polyacrylonitrile base carbon cloth as the raw materials. Its ablative resistance, thermal shock resistance, airflow resistance, thermal insulation performances are very good, so it is mainly used in vacuum metallurgy industrial furnaces (high pressure gas quenching furnace, low pressure sintering furnace, pressure vacuum sintering furnace).

Hard composite carbon fiber felt is processed by special technology of solidification and setting, and secondary high-temperature purification treatment with graphite foil, polyacrylonitrile base carbon felt and polyacrylonitrile base carbon cloth as the raw materials

Description

Its ablative resistance, thermal shock resistance, airflow resistance, thermal insulation performances are very good, so it is mainly used in vacuum metallurgy industrial furnaces (high pressure gas quenching furnace, low pressure sintering furnace, pressure vacuum sintering furnace).

Features

1.High purity, high carbon content.

2. Anti-ablative performance and thermal shock resistance.

3.The performance is superior to airflow scouring and thermal insulation and thermal insulation performance.

Application

It is mainly used in ultra-high temperature vacuum high-pressure sintering furnaces as well as electronics, semiconductor industry, solar photovoltaic (polycrystalline casting furnace, single crystal furnace) and vacuum industrial furnace equipment.
