Product Description

PIR Rigid Polyurethane Foam Insulation Board Cryogenic Performance Low Thermal Conductivity for LNG Tank

Product Description

PIR Rigid Polyurethane Foam Insulation Board is made from polyisocyanurate (PIR) foam whose modified structure adds isocyanurate ring linkages, giving better thermal stability than standard PUR.

The board keeps a very low thermal conductivity of about 0.022 W/(m·K) at 25°C and around 0.017–0.019 W/(m·K) at –100°C, which is essential for deep-cold service.

A closed-cell content of 95% or more sharply limits water and vapour ingress, protecting insulation performance where condensation and frost are constant risks.

The panel is dimensionally stable at cryogenic temperatures and, with proper expansion joints, tolerates the thermal contraction of deep-cold systems without cracking.

Typical applications include LNG storage tanks, cryogenic pipelines, liquefied gas terminals and low-temperature petrochemical units operating down to –196°C.

Product Features

Cryogenic High-Temperature Resistant – Stable from –196°C to +120°C for deep-cold and moderate-heat duty.

Low Thermal Conductivity – About 0.022 W/(m·K) at 25°C cuts heat gain in cryogenic service.

Closed-Cell Waterproof – Above 95% closed cells block vapour and water penetration.

Dimensional Stability – Low shrinkage at cryogenic temperatures keeps panels tight and sealed.

Fire Retardant B1 Grade – Self-extinguishing PIR foam reaches B1 fire classification.
