Ceramic Fiber Cloth: A Comprehensive Guide for Buyers in 2025
In industries requiring high-temperature insulation, ceramic fiber cloth stands out as a versatile and durable solution. Whether you're in manufacturing, aerospace, or energy, understanding this material's properties and sourcing options is crucial. This guide covers key aspects to help you navigate the market effectively.
How to Find Reliable Ceramic Fiber Cloth from China in 2025
China remains a leading producer of ceramic fiber cloth, offering competitive pricing and quality. To identify trustworthy suppliers:
- Check certifications like ISO 9001 and product-specific test reports
- Review supplier history on platforms like Alibaba (minimum 3 years preferred)
- Request samples to verify material consistency
- Confirm MOQs and lead times match your project needs
Top manufacturing regions include Shandong and Jiangsu provinces, where 60% of global production occurs.
What Buyers Should Know Before Buying Ceramic Fiber Cloth from China
Key considerations when importing:
| Factor | Details |
|---|---|
| Shipping Costs | FOB prices typically 30-40% lower than domestic alternatives |
| Customs Clearance | HS Code 6813.90 applies for most ceramic fiber products |
| Quality Variations | Density ranges from 128kg/m³ to 256kg/m³ affect performance |
Types of Ceramic Fiber Cloth
Three primary variants dominate the market:
- Standard Grade - Withstands 1260°C, most economical
- High Purity - 99% alumina content for 1400°C environments
- Zirconia Enhanced - Resists 1600°C, used in extreme conditions
Functions and features of Ceramic Fiber Cloth
This material excels in:
- Thermal insulation (reducing heat transfer by up to 75%)
- Chemical resistance against most acids and alkalis
- Flexibility allowing complex shaping
- Low thermal conductivity (0.12 W/m·K at 1000°C)
Scenarios of Ceramic Fiber Cloth
Common applications include:
- Furnace and kiln insulation
- Welding protection blankets
- Expansion joint seals in refineries
- Aircraft engine compartments
A recent case study showed a steel mill reducing energy costs by 18% after installing ceramic fiber insulation.
How to Choose Ceramic Fiber Cloth
Selection criteria:
- Determine maximum operating temperature
- Assess required tensile strength (typically 5-15 N/cm)
- Consider chemical exposure
- Evaluate thickness needs (1mm-12mm available)
Ceramic Fiber Cloth Q & A
Q: Is ceramic fiber cloth safe for food processing equipment?
A: Not recommended - silica dust release requires containment in food-grade applications.
Q: How does ceramic fiber compare to fiberglass?
A: Ceramic withstands 3-4x higher temperatures but costs approximately 50% more.
Q: What's the typical lifespan?
A: 2-5 years depending on thermal cycling frequency and mechanical stress.
Q: Can it be sewn or modified?
A: Yes, specialized high-temperature thread allows custom fabrication.
Q: Are there eco-friendly alternatives?
A: Bio-soluble fibers exist but have lower temperature ratings (800°C max).
