Product overview
EXNP-O โ All-Sides OS Coated Carbon Fiber Insulation Board
The EXNP-O receives Expo's proprietary Oxidation-Shield (OS) coating on all six faces. This makes it suitable for furnaces that cycle between inert and atmospheric conditions, extending board service life significantly compared to uncoated grades.
Key Features
- Full OS coating on all sides โ complete oxidation resistance
- Extends service life in furnaces with air exposure during loading
- Prevents surface erosion and carbon dust generation
- Hard outer shell maintains dimensional stability over many cycles
- Available in flat panels; custom machined shapes on request
Applications
- Batch vacuum furnaces with frequent atmosphere cycling
- Carbon fiber heat treating furnaces
- Powdered metal sintering furnaces
- Hot-pressing moulds and die insulation
