High Heating Resistance Soft PAN Based Graphite Felt For
Soft graphite felt is the high heating resistance and thermal
insulation materials, it is a 3m to 12mm thickness, PAN based
graphite mat, which through high heat processing, is high heating
resistance , Be widely used in all kinds of high temperature vacuum
furnace heat insulation heat preservation material,also can be used
as C/C composites reinforced material,because 94% of carbon felt as gap, with a light weight and soft ,small heat
capacity, good insulation,convenient operation.

Soft graphite felt in 3mm to 12mm thicknesses to meet a wide range
of applications. Felt material is generally used as thermal
insulation in inert and vacuum furnaces. For special applications,
this felt is available with graphite coatings, which will reduce
the permeability of the felt and improve its resistance to erosion.
These products are easy to cut and install and can be sewn in place
using Chemshine carbon cordage. Additionally, Chemshine carbon felt
is also available in a rigid form that is able to be manufactured
into shapes including Baffles, Cylinders and Rings.
Our products are mainly used as insulation in high-vacuum and inert
atmosphere furnaces. This kind of high-vacuum is widely used for
metal heat treatment, meticulous and ceramic sintering, different
kinds of crystallization production, producing optical fiber, and
sintering monocrystalline silicon for semiconductors, usually in a
high-vacuum or inert atmosphere furnace. Since these furnaces work
at extremely high temperatures, it is necessary to have insulation
material that can withstand such high temperatures. Moreover, for
energy conserving purposes, quality heat insulation material is the
best choice. We pride ourselves in the ability to offer first class
technical backup to our customer base, and over the years we have
developed close technical partnerships with major fields including
