High Temperature Sandwich Structure Rigid Composite Cartbon-Carbon Felts Cylinder

The HT grade of rigid graphite felt are shaped insulating materials made by graphitization after forming graphite felt into the customers' requested shape, such as plate, cylinder, etc. With our special technologies under the high emperature, the density is less than 0.18g/cc, and the carbon content is more than 99.9%. So they are suitable in all types of heat treating furnaces in an inert or vacuum environment.

Hard Composite Carbon Filber Felt Specification And Description

Carbon Boards (1200ºC heat treated) are rigidized PAN long fiber felt.
Only Stocked in 60in x 40in x all thickness on Pricing sheet with foil on 2 sides. Raw and one sided carbon board has a 1-3 week lead time.
Graphite Boards (2000ºC heat treated) are shaved Rayon foam stocking in (60 x 40in) & (52 x 24in) size with foil on 1 side for shipping in 1 week.
Boards can be lined (covered) on one or both sides with;
Graphite foil (0.015 in. thick) = add $50 per side.
CFC (carbon-fiber-composite) (0.030 in. thick) = add $250 - $450 per side.
Board thickness capability up to 20 in. thick
High temperature heat treatment up to 2600°C & halogen purification available. Priced at time of quote.
Rigidized felt has courser fiber & so better for oxidation resistance & heat treating vacuum furnace or hot pressing applications.

Hard Composite Carbon Filber Felt Direction For Use

Graphite rigid insulating boards in PAN rigidized felt or Rayon sliced foam are used insulation for vacuum & protective atmosphere process furnaces.
The boards are easily cut or machined to size to fit both square and round hot zones.
The boards can be machined into complex shapes and made to print in large sizes
Surfaces & cut edges can be sealed using our Graphite Coating.
Repairs and connections are made using one of our family of Graphite Adhesives.
Graphite foil added to the surface or layered in the board increases radiant heat retention significantly as wellas reduces issues with furnace contaminent containment
Foil helps decrease pump down times and increase longevity of the insulation.
Similarly, CFC covering on the boards gives durability, impact & wear resistance.
