Cryogenic-Grade Expanded Perlite – Specialized Insulation Solution for Cold Boxes & LNG Tanks

Cryogenic-Grade Expanded Perlite is a premium inorganic thermal insulation material produced from natural volcanic rock ore, expanded at high temperatures with strict control over moisture content and particle size distribution. This product is specifically engineered as loose-fill insulation for ultra-low temperature systems, including Cold Boxes in Air Separation Units (ASU), cryogenic storage tanks (LNG, Liquid Oxygen, Liquid Nitrogen, Liquid Argon), and industrial facilities requiring absolute fire and explosion safety standards.

1. Technical Specifications

Supplied by SCG Vietnam, our product meets the most stringent standards of the liquefied gas and air separation industries:

• Particle Size: 0.1 – 1.2 mm

• Loose Bulk Density: 35 – 55 kg/m³

• Vibrated Bulk Density: 48 – 65 kg/m³

• Moisture Content: ≤ 0.3% (by weight)

• Thermal Conductivity: ≤ 0.022 W/(m·K) (mean value from 77 K to 310 K, atmospheric pressure)

2. Key Advantages of Cryogenic Perlite

• Superior Thermal Insulation Performance: With an ultra-low thermal conductivity (≤ 0.022 W/(m·K)), the material virtually eliminates heat ingress from the external environment into cryogenic temperature zones (down to -196°C), maximizing energy savings for refrigeration compressors.

• Ultra-Low Moisture Content (≤ 0.3%): Completely eliminates the risk of moisture freezing within the insulation layer, preventing increases in thermal conductivity as well as corrosion or damage to piping systems and distillation columns.

• High Flowability & Complete Void Filling: The fine 0.1 – 1.2 mm particle size allows the material to flow effortlessly into complex spaces around pipes and equipment inside Cold Boxes where rigid foam boards cannot reach.

• Ultra-Lightweight & Mechanically Stable: A loose bulk density of just 35 – 55 kg/m³ minimizes structural load on tanks and steel casings. Stable vibrated density ensures the material does not settle, compact, or clump during long-term operation.

• Absolute Fire & Explosion Safety: As a natural inorganic mineral, Perlite is non-combustible, produces no toxic smoke, and is completely chemically inert (non-reactive even in direct contact with Liquid Oxygen).

3. Industrial Applications

• Air Separation Units (ASU): Loose-fill insulation for the entire interior space of Cold Boxes.

• Cryogenic Storage Tanks: Double-walled insulation for LNG, LPG, Liquid Oxygen (LOX), Liquid Nitrogen (LIN), and Liquid Argon (LAR) storage tanks.

• Specialized Cryogenic Piping & Transport Tanks: Insulation for pipe-in-pipe liquefied gas lines, cryogenic road tankers, and ISO tank containers.

• Petrochemical & Energy Industries: Thermal insulation for distillation columns, heat exchangers, and CO₂ recovery and liquefaction systems.
