Cyclopentane, a cycloalkane widely used as a foaming agent and refrigerant-blowing agent, has seen steady production growth due to its eco-friendly characteristics compared to traditional CFCs and HCFCs. As global regulations around ozone-depleting substances tighten, cyclopentane has emerged as a favored alternative, driving capacity expansions in major markets like China, South Korea, and parts of Europe. Production capacity globally has increased moderately, with Asia-Pacific leading in both consumption and production. The growth is also supported by downstream industries such as polyurethane foam insulation in appliances and construction.
