1. Why the LNG Industry Needs a New Class of Insulation Materials
Liquefied natural gas (LNG) is stored at –162°C, creating extremely demanding conditions for insulation materials. Across storage, transportation, and regasification, the sector faces challenges such as:
Heat leakage and rising BOG (Boil-Off Gas) losses
Heavy insulation structures that increase vessel fuel consumption
Strict fire safety requirements in case of leaks or flash events
Tightening environmental regulations
Traditional materials like PU, PIR, rock wool, and phenolic foam struggle with durability, weight, flammability, and long-term stability at cryogenic temperatures.
YDNFoam™ melamine foam provides a next-generation solution that solves these problems with remarkable efficiency.

2. Ultra-Lightweight (4kg/m³): Reduced Structural Load and Higher Energy Efficiency
YDNFoam™ melamine foam weighs only 4kg/m³—far lighter than PIR, PUR, or phenolic alternatives.
Benefits for LNG systems:
Reduced load on LNG storage tank structures
Lower deadweight for LNG carriers → fuel savings and improved maneuverability
Easier handling and faster installation in EPC projects
Lower stress on pipeline supports and cryogenic process lines
A lighter system means lower operational cost and longer service life.

3. Inherent Fire Resistance: Meeting the Highest LNG Safety Standards
Melamine foam is inherently flame-resistant, achieving:
UL94 V-0
EN45545 HL1/HL2
DIN5510
B1-grade flame retardancy
Key advantages for LNG environments:
No melting
No dripping
Low smoke density
Low toxicity
In LNG plants—where leaks, sparks, and flammable vapors are critical risks—this level of fire safety adds a high-value security layer to storage tanks, cold boxes, piping, and onboard LNG systems.

4. Low Thermal Conductivity (0.032–0.035 W/m·K): Superior Cryogenic Insulation
Thanks to its fine open-cell microstructure (100–300 μm), melamine foam achieves a thermal conductivity of:
λ = 0.032–0.035 W/m·K
This provides significant benefits:
Reduced cold loss in storage tanks
Lower BOG generation
Higher efficiency for liquefaction and regasification systems
Reduced load on refrigeration and re-liquefaction units
Ideal for LNG terminals, FSRUs, FLNG units, cold boxes, and pipeline systems.

5. Wide Operating Temperature: –196°C to +200°C for All LNG Conditions
YDNFoam™ maintains structural stability across extreme temperatures:
–196°C → +200°C without shrinking, cracking, or powdering
This wide temperature envelope makes it ideal for:
Cryogenic transfer pipelines
LNG cold boxes and subcooling units
Offshore LNG plants (FLNG/FPSO modules)
Storage tank outer shell insulation
Regasification system hot and cold zones
It withstands rapid temperature cycling, outperforming PIR, PE foam, and phenolic systems.

6. Environmentally Compliant: Halogen-Free and Low-VOC for Global LNG Projects
In global LNG EPC and marine projects, environmental compliance is now non-negotiable.
YDNFoam™ meets:
EU REACH
EU RoHS
California Prop 65
IMO and marine environmental guidelines
The material is:
Halogen-free
Low-VOC
Non-toxic during use
Fully aligned with ESG and green construction initiatives
This helps LNG operators meet sustainability targets and pass international audits.

7. Easily Machinable for Complex LNG Equipment Structures
YDNFoam™ can be engineered into:
Boards, rolls, blocks
Pipe shells and curved sections
Laminates with aluminum foil, fiberglass cloth, or anti-corrosion films
Precision-cut components for cold boxes and process skids
Its ease of fabrication significantly improves installation efficiency in EPC projects and supports tailored solutions for complex LNG infrastructure.

8. Key Application Areas Across the LNG Value Chain
