Ceramic Fiber Board

Product Overview

Ceramic Fiber Board is manufactured from high-purity ceramic fiber and binders through a vacuum forming process. It features low thermal conductivity, excellent high-temperature stability, uniform density, and superior thermal shock resistance.

The board is suitable for applications involving vibration, mechanical stress, and corrosive environments. It offers excellent rigidity and high strength, is self-supporting yet lightweight, and is easy to cut and machine.

Product Features

Low Thermal Conductivity

Excellent insulation, with conductivity as low as 0.065 W/m·K at 200°C.

High Rigidity & Strength

Self-supporting structure with strong mechanical properties, suitable for structural use.

Thermal Shock Resistance

Withstands rapid temperature changes and thermal cycling without cracking.

Easy Machining

Easily cut, drilled, and machined to precise dimensions for custom applications.

Uniform Density

Vacuum forming ensures consistent density and performance throughout the board.

Chemical Resistance

Resistant to most chemical corrosion, except hydrofluoric and phosphoric acid.
