Ceramic Fiber Boards: A Complete Guide for Buyers in 2025
Ceramic fiber boards are essential insulation materials widely used in high-temperature industrial applications. With increasing demand from sectors like metallurgy, petrochemicals, and power generation, understanding these boards is crucial for buyers. This guide provides practical insights for sourcing quality ceramic fiber boards in 2025.
How to Find Reliable Ceramic Fiber Boards from China in 2025
China remains the world's leading manufacturer of ceramic fiber boards, offering competitive prices without compromising quality. When sourcing from China:
- Verify supplier certifications (ISO 9001, SGS reports)
- Request product samples for density and thermal conductivity tests
- Check production capacity and lead times
- Review export experience to your region
Top manufacturing hubs include Shandong and Henan provinces, where over 60% of China's ceramic fiber production occurs.
What Buyers Should Know Before Buying Ceramic Fiber Boards from China
Key considerations include:
- Moisture resistance: Critical for outdoor applications
- Temperature ratings: Standard boards withstand 1260°C, high-purity versions up to 1430°C
- Custom sizing: Many Chinese suppliers offer cutting services
- Shipping costs: Lightweight nature reduces freight expenses
Types of Ceramic Fiber Boards
Three main varieties dominate the market:
- Standard boards (1260°C) - Most common for general industrial use
- High-purity boards (1430°C) - For extreme temperature environments
- Zirconia-enhanced boards (1600°C) - Specialized applications
Functions and features of Ceramic Fiber Boards
These boards excel in:
- Thermal insulation (low conductivity: 0.09-0.12 W/m·K at 200°C)
- Energy efficiency (reducing furnace heat loss by 30-50%)
- Chemical stability (resistant to most acids and alkalis)
- Easy installation (can be cut with woodworking tools)
Scenarios of Ceramic Fiber Boards
Common applications include:
- Furnace linings in steel plants
- Boiler insulation in power plants
- Kiln furniture in ceramic industries
- Expansion joints in petrochemical facilities
How to Choose Ceramic Fiber Boards
Selection criteria:
| Factor | Consideration |
|---|---|
| Temperature | Choose board with 100-200°C higher rating than operating temp |
| Density | 240-320 kg/m³ for most applications |
| Thickness | 25-50mm typical for furnace walls |
