Cyclopentane: Driving Efficiency in Insulation and Refrigeration
Published
October 8, 2025
Cyclopentane has become the foam blowing agent of choice for both construction and refrigeration industries. With a global search volume approaching a million per month, interest is rising — and for good reason.
What is Cyclopentane?
Cyclopentane is a hydrocarbon widely used as a foam blowing agent in polyurethane insulation foams. It can also be utilized in combination with co-blowing agents such as Trans 1,2 Dichloroethylene and methyl acetate to realize improved thermal resistivity and higher R-values.
Applications in Construction
In commercial and residential construction, energy-efficient insulation is no longer optional — it’s essential. Cyclopentane-based foams deliver:
- High R-Value: Improving thermal performance in walls, roofing systems, and panels.
- Reduced Energy Demand: Lower heating and cooling costs for building owners.
- Sustainability: Ozone-depleting substances like CFCs and HCFCs have been phased out; Cyclopentane offers an eco-friendly alternative with zero Ozone Depletion Potential (ODP).
Applications in Refrigeration
Refrigeration systems, from household refrigerators to large commercial units, rely on insulation that balances performance with safety. Cyclopentane blends with Trans 1, 2 Dichloroethylene provide:
- Improved R-Value: Maintaining stable internal temperatures while lowering compressor workload.
- Energy Savings: Enhanced system efficiency translates to lower electricity costs.
- Durability: Strong foam structures that extend equipment life.
- Improved Fire Safety: Trans 1, 2 Dichloroethylene, when blended with cyclopentane, improves overall fire safety of polyurethane foam.
The Bottom Line
From construction sites to supermarket aisles, cyclopentane powers the next generation of insulation and refrigeration. For builders and manufacturers, the right blowing agent isn’t just about compliance, it’s about performance, efficiency, and long-term sustainability.
