Melamine Foam for LNG Applications: Insulation & Safety Solution
Melamine foam is a specialized material engineered for LNG (Liquefied Natural Gas) systems, addressing critical needs in thermal insulation, safety, and lightweight design. Its closed-cell structure and low thermal conductivity (0.02–0.04 W/m·K) make it ideal for maintaining cryogenic temperatures in LNG storage tanks, pipelines, and transport vessels. By minimizing heat ingress, the foam ensures LNG remains in its liquefied state, reducing boil-off losses and enhancing operational efficiency.
Key Advantages for LNG Systems:
- Extreme Low-Temperature Resistance: Maintains structural integrity and insulation performance at -162°C, the boiling point of LNG, without brittleness or degradation.
- Flame Retardancy & Safety: Composed of inherently fire-resistant melamine resin, it meets global safety standards (e.g., API 620 for storage tanks, ISO 14620 for cryogenic insulation), resisting ignition and emitting minimal smoke or toxic fumes in high-risk environments.
- Lightweight & Compact: At 10–20 kg/m³, it reduces overall system weight by 40% compared to traditional insulation materials like polyurethane foam, optimizing transport efficiency and installation ease.
- Vibration & Moisture Resistance: Its resilient structure withstands mechanical stress in LNG transport and prevents moisture absorption, ensuring long-term reliability in harsh conditions.
Applications in LNG Infrastructure:
- Storage Tanks: Lined within inner walls or between tank layers for thermal barrier protection.
- Cryogenic Pipelines: Used as pre-insulated jacketing to maintain low temperatures during long-distance transport.
- LNG Carriers & Trucks: Installed in cargo holds and engine compartments to balance thermal control and safety.
Easy to fabricate into custom shapes (e.g., sheets, tubes) and compatible with adhesive or mechanical fastening, melamine foam offers a versatile, high-performance solution for modern LNG applications, ensuring safety, efficiency, and compliance with industry standards.
