Product overview
EXNP-H — Hybrid Surface Treatment Carbon Fiber Insulation Board
The EXNP-H is Expo's premium configuration: OS coating on one face combined with either graphite foil or CFC fabric on the opposite face. This hybrid approach lets engineers optimise each surface for its specific function within the furnace — oxidation protection on the exposed outer face and radiation shielding or abrasion resistance on the inner hot-face.
Key Features
- OS coating on one side + graphite foil or CFC fabric on opposite side
- Optimised for applications requiring dual surface functionality
- Outer OS face resists oxidation during atmosphere cycling
- Inner foil/CFC face improves thermal reflectivity or abrasion resistance
- Manufactured to order; specify hot-face treatment at time of enquiry
Applications
- Vacuum furnace outer insulation panels (OS outside / foil inside)
- Crystal growing furnaces requiring contamination control
- High-cycling industrial furnaces needing extended board life
- Custom hot-zone insulation assemblies
