1. Background: Lightweight and High-Performance Needs in Aerospace
Modern aerospace engineering demands materials that combine lightweight design, acoustic control, and superior thermal stability under extreme environments.
Within satellite and spacecraft cabins, heat transfer, vibration, and resonance can compromise both comfort and equipment performance. As payload costs remain high, every gram saved matters. Engineers are turning to ultra-light, clean, and flame-retardant foams that can perform reliably from vacuum to high-temperature cycles.

2. Material Overview: YDNFoam™ 4 kg/m³ Aerospace-Grade Melamine Foam
YDNFoam™ develops next-generation melamine foam engineered for aerospace and satellite applications.
At an ultra-low density of 4 kg/m³, it delivers an unmatched balance of thermal insulation, acoustic absorption, flame retardancy, and low VOC performance, making it ideal for satellite cabin acoustic/thermal lining, launch vehicle insulation, and space module panels.

3. Application Principle and Performance Advantages
(1) Acoustic Damping Inside Satellite Cabins
The open-cell microstructure of YDNFoam™ efficiently dissipates sound energy into heat through air friction.
This significantly reduces mid- to high-frequency resonance (500 Hz – 4000 Hz) within satellite cabins, protecting sensors and improving communication signal clarity.
(2) Thermal Control and Energy Management
Operating in orbit exposes spacecraft to extreme radiation and cryogenic cycles.
YDNFoam™’s low thermal conductivity and stable molecular structure provide outstanding thermal isolation, helping maintain uniform cabin temperatures and stable instrument performance.
(3) Safety and Cleanroom Compatibility
Unlike PU or PE foams that release particulates and VOCs, YDNFoam™’s inorganic polymer network ensures:
Low outgassing
No particulate shedding
Halogen-free flame retardancy
This makes it fully compliant with aerospace cleanroom and outgassing standards (e.g., NASA TM-102260).

4. Engineering Applications
(1) Satellite Cabin Acoustic/Thermal Layer
Placement: Internal cabin sidewalls, equipment modules, and payload compartments
Function: Dampen vibration and acoustic noise while minimizing thermal gradients
Configuration: YDNFoam™ core + aluminized PET film + flame-retardant nonwoven (5–20 mm)
(2) Rocket Interstage Thermal Protection
Applied between structural segments for heat insulation and vibration absorption
Reduces total system weight by ≈ 45% vs glass wool solutions
Supports easy modular installation
(3) Space Suit and Life-Support Layer
Used as breathable, soft insulation in astronaut suit liners
Non-toxic, odorless, and compliant with low-outgassing requirements
