    Cyclopentane CAS 287-92-3

    Cyclopentane (CAS 287-92-3), chemically classified as a alicyclic hydrocarbon or Pentamethylene, is a colorless, flammable liquid used extensively as a blowing agent in the polymer industry. Distinct from linear pentane isomers, this cycloalkane serves as a critical replacement for HCFCs in the production of rigid polyurethane insulation foams for refrigeration units and construction panels. It is also utilized as a specialized process solvent in the extraction and synthesis of resins and synthetic rubber. We provide this industrial material with competitive factory pricing to support continuous manufacturing operations, alongside options for customized specifications. Essential technical documentation, including MSDS, TDS, COA, is readily available for all bulk supply orders.
