What is Cyclopentane?
Cyclopentane (C₅H₁₀) is a highly pure hydrocarbon solvent and blowing agent primarily used in the production of rigid polyurethane (PU) foam for insulation panels, refrigerators, and construction materials.
It offers an ideal balance of performance, cost efficiency, and environmental safety, replacing HCFC and HFC blowing agents globally.

Cyclopentane is clear, colorless, and has a mild hydrocarbon odor. It is widely recognized as the preferred eco-friendly blowing agent for modern insulation manufacturing.
Applications of Cyclopentane
Polyurethane Foam Blowing Agent
Cyclopentane is widely used as a physical blowing agent in rigid PU foam systems for refrigerators, freezers, and insulated panels.
It ensures fine and uniform foam cell structure, resulting in improved thermal insulation performance.
Refrigeration and Insulation Industry
In the refrigeration sector, Cyclopentane serves as a sustainable replacement for HCFC-141B and HFC-245fa.
Its low global warming potential (GWP) and zero ozone depletion potential (ODP) make it the leading solution for energy-efficient, environmentally friendly insulation foams.
Environmental Benefits
- Zero ODP (Ozone Depletion Potential)
- Very low GWP
- Complies with EU F-Gas Regulations
- 100% non-toxic and chlorine-free
Cyclopentane is the most sustainable choice for manufacturers transitioning to environmentally responsible insulation materials.
Advantages of Cyclopentane
- Excellent insulation performance
- Stable supply and consistent purity
- Cost-effective alternative to HFCs
- Safe for the ozone layer
- Compatible with existing PU foam systems
Cyclopentane combines performance, cost, and sustainability, making it the most widely used hydrocarbon blowing agent in global rigid foam production.
