Ceramic Fiber Board

Name: Ceramic Fiber Board
Brand: ZOUYU

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

FAQ

Frequently Asked Questions

Technical and commercial answers for this product. If your question is not here, our engineers will answer it directly.

How is ceramic fiber board made?

+

Board is produced by vacuum-forming a ceramic fibre slurry with a small amount of binder, then drying and curing it. The result is a rigid, self-supporting panel that can be cut, sawn and machined to close tolerances, unlike flexible blanket.

When should I use board instead of blanket?

+

Use board where the lining needs structural strength, resistance to gas velocity, or precise dimensional tolerances: furnace hot faces exposed to erosion, door seals and baffles, burner blocks, and back-up insulation behind dense refractory.

What strength and density does the board have?

+

Bulk density is 320-350 kg/m³ across all grades, with compressive strength of 0.08-0.12 MPa. That is substantially stiffer than needled blanket at 128 kg/m³, while remaining far lighter than dense firebrick.

What sizes and grades are available?

+

Standard sizes are 600 × 400 × 10-50 mm and 900 × 600 × 20-50 mm, in COM, ST, HP, HA and HZ grades covering classification temperatures from 1100°C to 1430°C.

Can board be machined or cut on site?

+

Yes. Board can be sawn, drilled and routed with standard woodworking tools fitted with appropriate dust extraction. Wear respiratory protection and use local extraction whenever cutting refractory fibre.
