Hydrofluoroolefins, or HFOs, are a class of chemicals used primarily as refrigerants and in foam-blowing applications. They are known for having a low global warming potential compared to traditional refrigerants like HFCs (hydrofluorocarbons). This makes HFOs a more environmentally friendly option in various industries. HFOs are produced through a chemical process that involves the reaction of hydrofluorocarbons with other compounds. They are gaining popularity due to their efficiency and reduced impact on climate change. As countries implement stricter regulations on greenhouse gas emissions, the use of HFOs is expected to increase in the coming years.
