Within the types dimension, the R32(Industrial difluoromethane) market is split between pure R32 refrigerant and R32‑based blends, each influencing overall market dynamics differently. Pure R32, a single‑component refrigerant, commands the majority share because it delivers the highest latent heat capacity and the lowest GWP among HFCs, making it the preferred choice for new‑generation equipment designed for direct R32 integration. R32‑based blends, such as R‑410A (R32/R125) and emerging low‑GWP mixtures (e.g., R‑452B, R‑454B), occupy a secondary niche, representing roughly 30 % of the volume. These blends are adopted primarily where legacy system retrofits are required or where performance trade‑offs—such as reduced flammability—are prioritized. The blend segment’s growth is moderated by the pace of equipment redesign and certification processes, whereas pure R32’s trajectory is closely tied to regulatory phase‑downs of higher‑GWP refrigerants, positioning it as the primary engine of market expansion.
