Soft PAN Based Graphite Felt Manufactured into Shapes For Crystal Growing Industry


Chemshine soft graphite felt can be manufactured into many kinds of shapes,like cylinders, rings, gaskets and boards.
The graphite mat can be used in crystal growing industy, it is a 3-10mm felt and through high heat processing.
It is high heating resistance ,Be widely used in all kinds of high temperature vacuum furnace heat insulation heat preservation material.
It can be used as C/C composites reinforced material,because 95% of carbon felt as gap,with a light weight and soft , small heat capacity, good insulation,convenient operation.

Soft graphite felt in 3-10mm thicknesses to meet a wide range of applications. The graphite mat 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. Over the years 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.
