Ceramic fiber blanket is a premium high-temperature refractory insulation material widely applied in industrial kilns, furnaces, boilers, pipeline insulation, and thermal equipment lining. If you are sourcing durable heat insulation solutions, you may be confused by various ceramic fiber blanket types and grades. Learning the key differences between each model helps you pick the right ceramic fiber blanket for your working temperature and industrial applications.
The main distinctions of ceramic fiber blanket grades focus on max temperature resistance, raw material formula, bulk density, thermal conductivity, high temperature shrinkage, and tensile strength. The mainstream types include 1260°C standard grade, 1280°C high purity grade, 1360°C high alumina grade, and 1430°C zirconia ceramic fiber blanket. Each grade is engineered for specific high-temperature working conditions.
°C
1260°C Standard Ceramic Fiber Blanket
1260°C standard ceramic fiber blanket is the most cost-effective option. Made of ordinary aluminum silicate fiber, it features light weight, low thermal conductivity, and stable heat insulation performance. It is perfect for conventional industrial furnaces, low and medium temperature kiln lining, and general thermal insulation under 1000°C. For budget-friendly industrial insulation projects, standard grade ceramic fiber blanket is always the preferred choice.
°C
1280°C High Purity Ceramic Fiber Blanket
1280°C high purity ceramic fiber blanket uses high-purity raw materials with fewer impurities. It delivers better oxidation resistance, lower high-temperature shrinkage, and longer service life than standard grade. This high purity ceramic fiber blanket is commonly used in metallurgical equipment, chemical thermal insulation, and medium-temperature industrial furnace lining.
°C
1360°C High Alumina Ceramic Fiber Blanket
1360°C high alumina ceramic fiber blanket contains higher alumina content, supporting long-term service at up to 1300°C. It provides excellent high-temperature stability, great tensile strength, and superior thermal insulation effect. High alumina ceramic fiber blanket is ideal for ceramic kilns, high-temperature industrial furnaces, and harsh refractory lining environments.
°C
1430°C Zirconia Ceramic Fiber Blanket
1430°C zirconia ceramic fiber blanket belongs to the high-end insulation grade. With zirconia added in the formula, it withstands ultra-high temperature up to 1350°C, featuring corrosion resistance, tiny thermal shrinkage, and stable long-term performance. It is widely used in petrochemical, aerospace, and large ultra-high temperature industrial furnaces.
Ceramic Fiber Blanket Grade Comparison
| Grade | Max Temp | Key Feature | Typical Application |
|---|---|---|---|
| Standard | 1260°C | Cost-effective, light weight | General industrial furnaces |
| High Purity | 1280°C | Low shrinkage, longer service life | Metallurgical & chemical equipment |
| High Alumina | 1360°C | High stability, strong tensile strength | Ceramic kilns, harsh environments |
| Zirconia | 1430°C | Ultra-high temp, corrosion resistant | Petrochemical, aerospace |
Density & Thickness Options
Apart from temperature grades, ceramic fiber blankets also vary in density and thickness. Common densities are 96kg/m³, 128kg/m³ and 160kg/m³; regular thickness ranges from 10mm to 50mm. Higher density means better structural strength and lower heat loss.
