Junyuan Petroleum Group manufactures Cyclopentane at 95%+ purity for rigid polyurethane (PU) foam production. This colorless liquid works as a next-generation blowing agent. It replaces ozone-depleting CFCs and HCFCs under the Montreal Protocol phase-out. Cyclopentane serves fluorine-free refrigerator and freezer manufacturing, along with cold storage and pipeline insulation applications. Older CFC and HCFC-based agents face regulatory phase-out. Cyclopentane is becoming the primary choice for PU foam blowing across these industries. Junyuan supplies Cyclopentane in ISO tanks (25/26 CBM) or steel drums. Technical data sheets cover purity, density, and moisture content.
