Product Introduction
Ceramic Fiber Board is a high-performance insulating product made from ceramic fiber and adhesive under vacuum. With even distribution of ceramic materials, it offers excellent heat insulation. Its low thermal conductivity and heat storage reduce energy costs and protect against thermal shock and chemical damage, making it ideal for tunnel construction, furnaces, and insulation.
Feature:
- Low heat conduction.
- Excellent thermal stability.
- High compressive strength.
- Fire-resistant.
- Strong wind corrosion resistance.
Application:
- High-temperature furnaces and kilns
- Aerospace industry
- Back-up insulation for refractory linings.
- Sealing gaskets for high temperatures.
- Anti-scour lining parts.
- Heating device insulation.
- Furnace door and body filling material.
