Hydrocarbon blowing agents, such as cyclopentane, isopentane, and n-pentane, are essential in the manufacture of polyurethane foams, providing an environmentally safer alternative to halogenated blowing agents. The production of hydrocarbon blowing agents has steadily expanded, supported by rising demand from insulation, refrigeration, and construction sectors. Asia-Pacific remains the largest production hub, with China and India showing significant capacity additions due to lower feedstock prices and favorable regulatory environments. Europe and North America, on the other hand, have focused on modernization of facilities to improve process efficiencies and reduce VOC emissions.
