Oxidizedfilament cured carbon feltand graphite felt
（1）Productdescription
This product is made of oxidizedsilkcarbon felt or graphite felt. It has a certain rigidity, self-supporting,smallspecific gravity, no short fiber shedding, low thermal conductivity,goodthermal insulation performance, the highest service temperature can reach3000 ℃. It is suitable for all kinds ofvacuumheat treatment furnace, pressure sintering furnace, reaction sinteringfurnace,monocrystalline silicon draw crystal furnace, polysilicon ingot furnaceand soon. It can provide all kinds of shapes such as flatplate, disc, cylinderand so on. The service life is long and easy to beinstalled and dismantled.
