Ceramic Fiber Board

Rigid vacuum-formed boards for high-strength thermal insulation and structural applications

Ceramic Fiber Board - Vacuum-Formed Rigid Insulation

Product Overview

ZOUYU ceramic fiber boards are manufactured using a vacuum-forming process that produces rigid, high-density boards with excellent dimensional stability and compressive strength. The boards are precision-cut to standard or custom dimensions, providing a reliable insulation solution for applications requiring structural integrity at elevated temperatures.

Key Features

  • High compressive strength (0.08-0.12 MPa) for load-bearing insulation
  • Excellent dimensional stability at high temperatures
  • Low thermal conductivity for superior insulation performance
  • Easy to machine, cut, and shape on-site
  • Uniform density distribution throughout the board
  • Resistance to thermal shock and gas erosion
  • Available in multiple standard sizes and custom dimensions

Applications

Industrial Furnace Linings Furnace Doors Shipbuilding Aerospace Fireproofing Sound Insulation Kiln Furniture Combustion Chambers
