Heat Insulation Soft Carbon Graphite fiber Felt
Product Description
Polyacrylonitrile based carbon fiber felt
Polyacrylonitrile base carbon felt is light in quality, small in specific heat capacity, soft in texture, good in adiathermancy and convenient in operation, which can save great energy. Therefore, thermal insulation of the polyacrylonitrile base is extremely superior in vacuum or inert atmosphere, in particular, performance of polyacrylonitrile base is stable under high temperature condition, and it is the excellent thermal insulation materials for vacuum furnaces

Polyacrylonitrile based carbon fiber felt
polyacrylonitrie base plumbago felt is formed by subjecting the high quality polyacrylonitrie base carbon felt to pyrographitetreatment. it is light quality, good in flexibility, high carbon content, high temperature reisistant, without volatilization under high temperature, corrosion esistant and small in heat conductivity coefficient and high in shape retention. it is fine heat insulator for polysilicon and monocrystalline silicon
