1. Core parameters
parameter categories |
typical values/Range |
Description |
thermal conductivity |
0.015–0.026W/(m·K)(Normal temperature)0.124–0.1597W/(m·K)(600℃) |
Normal temperature insulation performance is better than traditional materials2-5Times, still maintains low thermal conductivity at high temperatures. |
mechanical properties |
Compression strength:0.64–1.365MPaYoung's modulus:21.8MPa(Mullite enhanced) |
3DThe strength of printed mullite-enhanced model is significantly improved and supports complex structural applications. |
Density and porosity |
Density:160–240kg/m³Porosity:90%Above |
Ultra-lightweight (0.26g/cm³), high pore structure reduces heat conduction. |
thermal stability |
Temperature resistance range:-200℃To1000℃Fire resistance:1200℃Lower structural stability |
No decomposition and deformation at high temperature, throughTGAVerify oxidation stability. |
Hydrophobicity and fire protection |
Hydrophobic rate:≥98%Fire rating:AClass (non-combustible) |
Isolate liquid water and allow water vapor to pass through; it will not ignite in case of fire, protecting equipment safety. |
Thickness and size |
Thickness:3/6/10mm(Common) |
Flexible and easy to cut, adapting to narrow spaces such as pipes and batteries. |
2. Performance characteristics
1.Ultra-efficient insulation
Nanoporous network (porosity>90%) Significantly blocks heat conduction and convection, and has a low thermal conductivity at room temperature0.02W/(m·K), high temperature environment (600℃) is still superior to traditional materials.
2.Lightweight and space savings
The thickness is only that of traditional materials1/3~1/5, improve volume utilization in space-limited scenarios such as aviation and battery packs.
3.Long life and environmental protection
20Shrinkage rate over annual life, the thermal conductivity has no attenuation; it can be recycled to reduce industrial waste.
4.Comprehensive performance of safety protection
-fire preventionALevel: Flame retardant and stable structure at high temperatures to avoid the spread of fire;
-Hydrophobic and anti-corrosion: Protect pipelines and equipment from water vapor erosion;
-Seismic cushioning: Flexible fiber matrix absorbs mechanical stress and protects precision components.
5.convenient construction
Support on-site cutting and sewing to improve installation efficiency30%Above, transportation costs are reduced (lightweight coil material).
III. Application fields
Application field |
typical scenario |
central role |
new energy battery |
Thermal insulation mat between power battery cells and module protective layer |
Delayed thermal runaway (satisfaction"5There is no fire in minutes"National standard), insulation buffer, adaptationCTC/CTBNo module design. |
Aerospace |
Aircraft bulkhead insulation, engine compartment thermal protection, spacecraft high temperature components |
Weight loss and efficiency increase, and withstand ultra-high temperature airflow impact. |
industrial energy conservation |
Petrochemical pipelines (≤650℃), high-temperature steam pipeline, smelting furnace body |
reduce heat loss90%, replacing asbestos/Carcinogenic materials such as silicates. |
