As the Marketing Director of Junyuan Petroleum Group, I am proud to share our industry insights on Cyclopentane, highlighting its growing role in the global refrigeration market. Based on our observations at the 2025 China Refrigeration Exhibition, this article explores Cyclopentane’s applications, technological advantages, and market potential worldwide.

Cyclopentane: A Green Solution for Modern Refrigeration

The global refrigeration industry is rapidly moving toward high efficiency, low carbon emissions, and smart solutions. Cyclopentane, as an eco-friendly blowing agent and refrigerant, has emerged as a key material driving this green transformation.

Environmental Benefits and Industry Value

Cyclopentane offers zero Ozone Depletion Potential (ODP) and an extremely low Global Warming Potential (GWP), fully meeting the environmental standards outlined in the Kigali Amendment. At the refrigeration exhibition, we observed numerous companies demonstrating low-carbon technologies where Cyclopentane-based blowing agents are already widely applied in household appliances such as refrigerators and freezers.

Technological Innovation and Application Expansion

Junyuan Petroleum Group’s high-purity Cyclopentane products leverage optimized production processes and stringent quality control to achieve industry-leading thermal conductivity and anti-aging performance. In ultra-low-temperature heat pump systems, our Cyclopentane products reliably perform under conditions below -30°C, offering robust solutions for cold chain logistics and industrial refrigeration worldwide.

Market Demand and Outlook

Industry experts forecast that, with the global drive toward carbon neutrality, the demand for eco-friendly refrigerants such as Cyclopentane is expected to grow at an annual rate exceeding 20% over the next five years. Particularly in regions investing in clean heating, industrial waste heat recovery, and energy-efficient refrigeration, Cyclopentane-based solutions are poised to play a significant role.

Why a 20/80 Cyclopentane/n-Pentane Ratio is Widely Used in the Insulation Industry

In the world of polyurethane (PU) rigid foam insulation, blowing agents play a crucial role in determining foam quality, thermal insulation, and process efficiency. Among the many options available, a blend consisting of 20% Cyclopentane and 80% n-Pentane has emerged as a go-to solution for manufacturers seeking an optimal balance of performance and cost.

Why This Specific Blend?

Each component in the blend brings unique properties to the table:

• Cyclopentane is valued for its low thermal conductivity, allowing foams to achieve excellent insulation performance. It also has zero ozone depletion potential (ODP) and relatively low global warming potential (GWP), making it more environmentally friendly. However, it is more expensive and can pose challenges in flowability and evaporation rate during foam processing.

• n-Pentane, on the other hand, is more economical, with higher vapor pressure and better flowability, making it easier to process, especially in large-scale industrial applications. But used alone, it tends to result in larger, less uniform foam cells, which can compromise insulation performance.

By blending 20% Cyclopentane with 80% n-Pentane, manufacturers can harness the strengths of both components: the superior insulation of Cyclopentane and the process efficiency and cost benefits of n-Pentane.

Where Is This Blend Used?

This pentane mixture is widely applied in:

• Household Refrigerators & Freezers: Used in the insulation layer of refrigerator cabinets and doors, ensuring high energy efficiency and consistent thermal performance.

• Construction Insulation Panels: Applied in rigid PU foam boards for building walls and roofs, providing lightweight, effective thermal barriers.

• Cold Chain Logistics: Employed in the insulation of refrigerated trucks and containers, helping maintain low temperatures during transportation.

Environmental and Safety Considerations

While the blend is non-ozone depleting and has lower GWP than legacy blowing agents like CFCs or HCFCs, it is still flammable and must be handled with proper safety protocols. Many modern production lines are equipped with explosion-proof equipment and ventilation systems to safely manage pentane-based formulations.

Conclusion

The 20/80 Cyclopentane/n-Pentane blend is a prime example of how smart chemical engineering can optimize material performance while balancing economic and environmental concerns. As global demand for energy-efficient insulation grows, such formulations will continue to play a key role in sustainable manufacturing.
