High closed-cell polyisocyanurate foam

ASTM D1622 -200℃ LNG Pipe Insulation PIR Polyisocyanurate Foam

Product Description

PIR (Polyisocyanurate Foam) is a rigid insulation material tested in accordance with ASTM D1622. Known as a low thermal conductivity insulation material, PIR achieves thermal conductivity as low as 0.022 W/m·K and maintains excellent mechanical strength under -200℃ cryogenic conditions. Compared with traditional polyurethane, PIR provides higher compressive strength (≥200 kPa), superior fire resistance (Class 1 / B1), closed cell content ≥95%, and water absorption ≤2%. It is widely recognized as the preferred LNG pipe insulation material.

Applications

• LNG Cryogenic Pipeline Insulation: Ensures stable thermal performance at -200℃.

• Cryogenic Tanks & Cold Storage: Suitable for ethylene plants, LNG tanks, and refrigeration systems.

• Industrial & Building Insulation: Applied in petrochemical facilities, refrigeration networks, and energy-efficient buildings.

Key Advantages

1. Extreme Cryogenic Resistance – Stable down to -200℃.

2. Superior Thermal Efficiency – As a low thermal conductivity insulation material, it reduces energy consumption.

3. Fire Safety – Class 1 / B1 fire rating, Flame Spread Index <25.

4. Moisture Resistance – Closed cell content ≥95%, water absorption ≤2%.

5. High Mechanical Strength – Compressive strength ≥200 kPa, tensile strength ≥320 kPa.
