Aerospace & Defense
Lightweight, high-reliability aerospace insulation and fire barrier insulation for defense — aircraft cargo fire barriers, rocket engine shields, spacecraft re-entry blankets, ship fire divisions, and nuclear-spec radiation-hardened insulation for sensitive defense electronics.
Aerospace and defense impose the most demanding insulation requirements: not only extreme heat resistance, but also lightweight construction, high reliability and long service life. Cabin and cargo fire barriers must be non-combustible yet light; launch and re-entry systems need materials that survive instantaneous ultra-high temperatures; structural partitions must keep their strength under thermal and mechanical load.
Material Comparison
| Material | Best fit | Service temp | Key advantage |
|---|---|---|---|
| Rock wool | Cargo fire barriers, hangars | up to 650°C | Non-combustible, structural fire |
| Glass wool | Cabin & compartment insulation | up to 400°C | Lightweight, thermal comfort |
| Ceramic fiber | Engines, rockets, spacecraft | 800-1700°C | Ultra-high-temp, low mass |
| Calcium silicate | Fire partitions, bulkheads | 600-1000°C | High-strength fire structure |
Application Scenarios
Aerospace & Defense Application Scenarios
- Aircraft cargo fire barriers — rock wool layers stop cargo-zone fires from reaching the cabin.
- Aircraft cabin insulation — glass wool regulates cabin temperature with minimal weight.
- Rocket engine insulation — ceramic fiber shields engine components against instantaneous ultra-high temperatures.
- Landing gear & engine heat shields — ceramic fiber blankets protect airframes during high-heat operation.
- Spacecraft re-entry blankets & suit liners — multi-layer ceramic fiber composites protect vehicles and crew during re-entry and EVA.
- Reusable launch vehicle fuel-tank insulation — ceramic fiber textiles stabilize propellant temperatures.
- Hypersonic vehicle thermal seals — woven spring-ceramic fiber seals rated to around 900°C for crewed and experimental vehicles.
- Aircraft fire partitions & ship bulkheads — calcium silicate boards provide high-strength, non-combustible dividers.

Frequently asked questions
What insulation is used for rocket engine components? +
Ceramic fiber blankets and boards with transient temperature resistance up to 1700°C, plus multilayer composites for re-entry thermal shields and suit liners.
Can you provide hypersonic thermal seals? +
Yes. Braided spring-ceramic fiber thermal seal assemblies (developed by space agencies) withstand around 900°C for spacecraft and X-series vehicles.
Do you supply aircraft fire barriers? +
Yes. Calcium silicate partitions between cabin and cockpit, and rock wool cargo-compartment fire layers, meet aviation fire-rating needs.
What is aerospace fire barrier insulation? +
It is the insulation that contains a fire within a designated zone on an aircraft or defense platform — typically A1 rock wool for cargo-hold liners, calcium silicate partitions for cabin boundaries, and ceramic fiber where temperatures reach 1700°C. It must be lightweight, non-combustible, and hold its shape under vibration.
What is aerospace nuclear insulation? +
Radiation-hardened thermal insulation specified for nuclear-powered vessels, reactor-adjacent systems, and rad-tolerant defense electronics. It combines thermal stability with low outgassing and radiation resistance, usually built from ceramic fiber or mica-based composites.
