Rayon Based Soft Graphite Fiber Felt for Pyrolytic Depositing
Chemshine rayon based soft graphite fiber felt is for pyrolytic
depositing furnaces. It is treated by a special process high temperature graphitization,with light weight,high carbon
content,ablation resistance, corrosion resistance, high purity,high
temperature without volatile,small coefficient of thermal
conductivity,without any deformation. The mat is also for heat
treatment furnaces or other vacuum furnaces.

Rayon based soft graphite felt or mat in customized thickness 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
Our ryaon based soft graphite mats 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. We have developed close technical partnerships
with major fields including Aerospace, Semiconductor, Automotive,
Specialist Castings, Metal Composites, Crystal Growing, Hard Metal
Sintering, Graphitizing, and the Heat Treat Sectors.
