Ustage:
Graphite felt 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 and Rings.
Application
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 Aerospace, Semiconductor, Automotive, Specialist Castings, Metal Composites, Crystal Growing, Hard Metal Sintering, Graphitizing, and the Heat Treat Sectors.
