Ceramic Fiber Blankets
Ceramic fiber blankets are versatile high-temperature insulation materials widely used in industrial applications. Known for their lightweight, thermal stability, and energy efficiency, these blankets offer excellent heat resistance up to 2300°F (1260°C). This guide explores their types, functions, and how to source quality products from China.
How to Find Reliable Ceramic Fiber Blankets from China in 2025
When sourcing ceramic fiber blankets from China, prioritize manufacturers with ISO 9001 certification and 5+ years of industry experience. Key platforms like Alibaba and Made-in-China list verified suppliers. Always request:
- Third-party test reports (ASTM C892 standard)
- Material Safety Data Sheets
- Production capacity proof (minimum 10,000㎡/month)
Top industrial zones include Shandong and Jiangsu provinces, where 60% of global ceramic fiber production originates.
What Buyers Should Know Before Buying Ceramic Fiber Blankets from China
1. MOQ Requirements: Most Chinese factories require 100-500㎡ minimum orders. Some accept sample orders under 50㎡ for testing.
2. Lead Times: Standard production takes 15-25 days. Express shipping adds 30-50% cost.
3. Payment Terms: 30% deposit with 70% balance before shipment is standard. Verified suppliers accept LC payments.
4. Customization: Available for density (64-128kg/m³), thickness (6-50mm), and alumina content (28-45%).
Types of Ceramic Fiber Blankets
Standard Grade (1260°C): Cost-effective for general industrial insulation
High-Purity (1400°C): Contains 99% alumina silica for extreme heat
Zirconia Enhanced (1600°C): Withstands corrosive environments
Bio-Soluble: Eco-friendly alternative with low biopersistence
Functions and Features of Ceramic Fiber Blankets
Key advantages include:
- Thermal conductivity as low as 0.12 W/m·K at 1000°C
- 50% better energy efficiency than traditional insulation
- Non-combustible (ASTM E136 Class A fire rating)
- Resistant to thermal shock and chemical corrosion
- Easy to cut and install with basic tools
Scenarios of Ceramic Fiber Blankets
Common applications:
Industrial Furnaces: Lining for steel, glass, and aluminum melting furnaces
Power Plants: Insulation for boilers and exhaust systems
Petrochemical: Pipe insulation in refineries
Aerospace: Thermal protection in spacecraft components
How to Choose Ceramic Fiber Blankets
Consider these factors:
1. Temperature Rating: Match to your operational needs (+200°C safety margin)
2. Density: Higher density (≥96kg/m³) for mechanical stress areas
3. Chemical Compatibility: Zirconia-enhanced for acidic/alkaline environments
4. Certifications: Look for ASTM C892, EN 1094, or GB/T 16400 standards
Ceramic Fiber Blankets Q & A
Q: Are ceramic fiber blankets safe?
A: Modern bio-soluble varieties pose minimal health risks when properly installed with protective layers.
Q: What's the typical lifespan?
A: 3-8 years depending on temperature exposure and mechanical wear.
Q: Can they be used outdoors?
A: Yes, but require waterproof coatings for prolonged exterior use.
Q: How do they compare to fiberglass?
A: Ceramic fibers withstand 2-3x higher temperatures but cost 40-60% more.
Q: What thickness is best for furnace lining?
A: 25-50mm is standard, with thicker installations for >1200°C applications.
