Description

Graphite Boards Foil Layered

Heat Treated Temp: 3632℉ | 2000℃

Grade: Graphite Insulation Board Foil Layered

Benefits
The boards can be made in complex shapes and made to print in large sizes. Please contact us for a custom quote.
Surfaces and edges can be sealed using our GraphiSeal to reduce porosity and improve oxidation resistance.
Boards can have foil added to the surface(s) or layered internally to increase radiant heat retention significantly while reducing issues with furnace contaminant containment.
Added foil aids in decreasing pump downtimes and increasing the longevity of the insulation.
Similarly, CFC covering on the boards provide durability, impact and wear resistance.
