Cyclopentane

Basic Information of Cyclopentane

Cyclopentane (CAS No. 287-92-3) is a colorless, highly flammable liquid with a petrol-like odor. It's known for its relatively low ozone depletion potential (ODP) and global warming potential (GWP), making it a popular choice as a more sustainable alternative to older, regulated blowing agents and solvents.

Key Applications of Cyclopentane

Cyclopentane is a widely used cyclic hydrocarbon primarily valued for its performance as an environmentally improved blowing agent and specialty process solvent. For a broader overview of hydrocarbon materials and industrial roles, refer to our industrial hydrocarbons guide.

• Blowing Agent for Polyurethane (PU) Foams: Cyclopentane is extensively used in the production of rigid polyurethane foams for thermal insulation in refrigerators, freezers, cold-chain equipment, and building panels. It has become a widely adopted alternative to HCFCs and HFCs due to its favorable environmental profile. For foam and refrigeration system context, see hydrocarbon blowing agents and refrigeration applications.

• Process Solvent: Serves as a solvent in selected polymerization systems, synthetic rubber processing, and for certain resins, fats, and oils where controlled volatility is required.

• Chemical Synthesis Intermediate: Used in the preparation of various organic intermediates within specialty chemical and fine chemical production workflows.

• Laboratory and R&D Use: Utilized in research environments for controlled reaction studies and analytical procedures involving cyclic hydrocarbons.
