Ceramic Fiber Paper: A Complete Guide for Buyers in 2025
Ceramic fiber paper is a lightweight, high-temperature insulation material widely used in industrial applications. Made from alumina-silicate fibers, it offers excellent thermal stability and resistance to chemical corrosion. This guide covers everything from sourcing reliable suppliers in China to practical usage scenarios.
How to Find Reliable Ceramic Fiber Paper from China in 2025
China remains the top exporter of ceramic fiber paper, but quality varies. Follow these steps to identify trustworthy suppliers:
- Check Alibaba Gold Supplier status and transaction records
- Request third-party test reports (e.g., SGS certifications)
- Verify production capacity through video factory tours
- Compare MOQs and lead times from 3-5 shortlisted vendors
Top-tier Chinese manufacturers like Luyang Energy-Saving Materials now offer customized thicknesses (1-10mm) with bulk order discounts.
What Buyers Should Know Before Buying Ceramic Fiber Paper from China
Critical considerations when importing:
| Factor | Details |
|---|---|
| Shipping Costs | Density affects freight - standard paper weighs 200-250kg/m³ |
| Import Duties | Typically 5-8% for most countries |
| Payment Terms | 30% deposit, 70% before shipment is standard |
Pro Tip: Request samples with your company logo printed to verify quality before bulk orders.
Types of Ceramic Fiber Paper
Three main varieties dominate the market:
- Standard Grade (1260°C max) - For general industrial insulation
- High Purity (1430°C max) - Contains ≥99% alumina-silicate
- Zirconia Enhanced (1600°C max) - Withstands extreme temperatures
Recent innovations include bio-soluble options for safer handling.
Functions and Features of Ceramic Fiber Paper
Key performance characteristics:
- Thermal conductivity: 0.12 W/m·K at 800°C
- Tensile strength: 0.5-1.2 MPa
- Chemical resistance to most acids/alkalis
- Low heat storage capacity
Case Study: A German steel mill reduced furnace energy loss by 18% after lining with 5mm zirconia-enhanced paper.
Scenarios of Ceramic Fiber Paper
Primary industrial applications:
- Furnace and kiln insulation
- Gasket material in high-temp equipment
- Thermal barriers in aerospace components
- Fireproofing in electrical systems
Emerging Use: EV battery thermal management systems increasingly adopt ceramic fiber layers.
How to Choose Ceramic Fiber Paper
Selection matrix based on needs:
| Application | Recommended Type | Thickness |
|---|---|---|
| Laboratory equipment | High purity | 1-3mm |
| Industrial furnaces | Zirconia enhanced | 5-10mm |
Always consider operating temperature +100°C safety margin.
Ceramic Fiber Paper Q & A
Q: Is ceramic fiber paper safe for food-grade applications?
A: No - standard versions contain breathable fibers. Only FDA-approved variants are suitable.
Q: How does it compare to fiberglass insulation?
A: Withstands 3-4x higher temperatures but costs 2-3x more per square meter.
Q: What's the typical lifespan?
A: 2-5 years depending on thermal cycling frequency and mechanical stress.
Q: Can it be cut or shaped onsite?
A: Yes - use sharp utility knives or die-cutters with proper PPE.
Q: Any disposal concerns?
A: Some regions classify it as special waste - check local regulations.
