Ultra-Low Temperature LNG Pipeline Cold Insulation Rigid PUR Foam System

Product Overview

Rigid Polyurethane Foam (PUR) is a closed-cell thermoset plastic foam formed by a chemical reaction between polyols/polyesters and polyisocyanates. Renowned as a highly efficient low-temperature insulation material, PUR is characterized by its extremely low thermal conductivity, exceptional strength, and superior resistance to moisture and water vapor. Stabilized with additives like flame retardants and stabilizers, our PUR foam offers consistent performance, making it the ideal choice for cold conservation and low-temperature insulation applications.

Key Advantages

• Exceptional Thermal Efficiency: Extremely low thermal conductivity for maximum energy savings.

• High Strength & Durability: Excellent compressive strength and dimensional stability for a long service life.

• Excellent Moisture Resistance: High closed-cell content effectively blocks water vapor and moisture ingress, preventing performance degradation.

• Lightweight & Easy to Handle: Reduces structural load and simplifies transportation, handling, and installation.

• Multi-Functional: Combines thermal insulation, acoustic damping, vibration resistance, and electrical insulation in one material.

Product Properties & Technical Data Sheet

Our product's key performance metrics meet or exceed industry standards, guaranteeing reliable quality.

What Our Key Specifications Mean for You:

• Low Thermal Conductivity (0.022-0.028 W/m·K): This core indicator of insulation performance is among the best in the industry, ensuring superior thermal efficiency.

• High Closed-Cell Content (≥90%) & Low Water Absorption (<3%): These synergistic properties guarantee outstanding resistance to moisture, ensuring long-term stable performance in humid environments.

• Broad Service Temperature Range (-200°C to +120°C): Makes it a perfect solution for a wide array of applications, from cryogenic insulation (e.g., LNG) to conventional low-temperature.

• Excellent Compressive Strength (≥150 kPa): Ensures the material withstands loads without deformation, ideal for applications like flooring and sandwich panels.

• Compliant Fire Ratings: Our products can be formulated to meet international fire safety standards such as B1 and Class 0, ensuring safer applications.

Primary Applications

• Industrial & Commercial Refrigeration: Insulation for refrigerated trucks, cold storage warehouses, freezers, and cooler walls.

• Building & Construction: Thermal insulation for building facades and roofs (commonly used in composite sandwich panels).

• Pipe & Tank Insulation: Cold and hot water pipes, and storage tanks in HVAC, petrochemical, and industrial plants.

• Transportation: Insulation and flotation material for ship hulls and vehicle bodies.

• Cryogenic Applications: Insulation for Liquefied Natural Gas (LNG) and liquid nitrogen/oxygen transportation and storage equipment.

• Other Industries: Solar water heaters, environmental chambers, etc.
