Composite Encapsulated Insulation
Our CEI grade provides the opportunity to design insulating packages unlike anything used in conventional furnaces. Carbon/Carbon composite shells are molded into complex geometries, fully encapsulating an insulating core of rigidized felt. Graphite foil also may be sandwiched between the felt layers creating a barrier to process gas infiltration and convection.
Typical Geometries: Curved Panels, Stepped Lids, Insulation Support Rings, and Bottom Assemblies.
Unlimited shapes and sizes can be produced to accommodate customer requirements.
The Carbon/Carbon composite shell protects the insulating core from damage during handling. CEI is well suited for insulation parts that must be manually removed from the furnace between thermal cycles or where some mechanical strength is needed in addition to insulating properties.
