Cryogenic-Grade Expanded Perlite Loose-Fill Thermal Insulation for Cold Box Systems

Cryogenic-grade expanded perlite is a lightweight, highly porous mineral insulation material designed for low-temperature and cryogenic thermal insulation applications, particularly in Cold Box systems. Its cellular structure contains a high volume of enclosed and interconnected air spaces, significantly reducing heat transfer and providing effective thermal insulation around process equipment.

In Cold Box applications, expanded perlite is typically installed as a loose-fill insulation material, allowing it to flow into and completely occupy the available spaces surrounding heat exchangers, piping, vessels, and other process equipment. This makes perlite particularly suitable for complex equipment arrangements where rigid insulation materials may be difficult to install or may leave uninsulated gaps.

The low bulk density and free-flowing nature of expanded perlite allow it to conform to irregular geometries and provide relatively uniform insulation throughout the Cold Box. Its inorganic and non-combustible composition also makes it well suited to industrial environments where thermal stability and reliable insulation performance are important.

Key Properties

• Low thermal conductivity for effective heat-transfer reduction

• Highly porous and cellular structure

• High air content within the expanded particles

• Low bulk density and lightweight construction

• Suitable for loose-fill insulation systems

• Easily accommodates complex equipment geometries

• Helps minimize uninsulated spaces and thermal bridging

• Inorganic and non-combustible mineral material

• Suitable for cryogenic and low-temperature industrial applications

Typical Applications

Expanded perlite is widely used as loose-fill insulation in Cold Box systems, cryogenic processing equipment, air separation units, LNG facilities, gas processing plants, and other industrial systems requiring low-temperature thermal insulation. It can be used around heat exchangers, piping, vessels, and other components to create a continuous insulating environment within the Cold Box.
