Your Trusted Partner in the Transition from 141b

With proven performance, global acceptance, and sustainable credentials, Cyclopentane is redefining the future of polyurethane insulation. If you’re a thermoware or foam manufacturer seeking a high-purity, export-grade blowing agent, our Cyclopentane is ready to ship.

As of April 28, 2025, the domestic price of Cyclopentane in China stands firm at RMB 11,200 per metric ton, approximately USD 1,555 per metric ton based on today’s official exchange rate (1 USD ≈ 7.2043 RMB).

After a significant adjustment in mid-April, the Cyclopentane market has remained stable for two consecutive weeks. This provides global buyers with a more predictable cost structure for sourcing.

Cyclopentane is a key blowing agent for polyurethane (PU) foam, extensively used in building insulation panels, refrigeration appliances, and cold chain logistics solutions. Stable pricing is crucial for industries targeting low-GWP and energy-efficient products. Global procurement teams are encouraged to leverage the current pricing stability for inventory planning and to mitigate risks linked to raw material price volatility during the second quarter of 2025.

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.
