Product features:High purity graphite felt is a kind of carbon fiber felt made of plant resin fiber. It has good heat preservation, low ash content and soft texture. It is a common insulating material for high-purity monocrystalline silicon furnace. It can be used for drawing monocrystalline silicon for p-type, n-type and high-purity chips.
