HFO vs. HFC Blowing Agents: What Are the Differences?

HFC stands for hydrofluorocarbon, and is a mix of hydrogen, fluorine, and carbon atoms. There are some issues with HFCs, which have led to many companies transitioning to HFOs. When you compare HFO vs. HFC, and realize the benefits of HFOs, you’ll learn how to avoid the dangers of HFCs and keep your operations compliant. 

At SprayWorks Equipment, we are proud to offer an HFO foam, an environmentally friendly alternative to the regular closed-cell spray foam. With over 100 years of experience, we are ready to provide you with cost-efficient and reliable solutions like these.

HFO vs HFC Blowing Agents

About HFO vs. HFC Materials

HFO vs. HFC blowing agents are a vital part of the makeup of spray foam. These chemical products help produce foam, and they also help slow down heat movement. Although they have similar functionalities and performances, there are quite a few differences between the two.


HFCs are a group of chemicals typically used for cooling and refrigeration equipment, blowing agents, aerosol propellants, and solvents. They are super greenhouse gases that are short-lived with atmospheric lifetimes between 15 and 29 years. While they don’t cause damage locally, they do harm the ozone layer, as they are known to have an effect one hundred times worse than carbon dioxide.

HFCs trap heat in our atmosphere and contribute to global warming, hence why there is a desire to switch over to a more environmentally friendly option. Many states have therefore banned HFCs due to their negative effects. 


For the best option when it comes to HFO vs. HFC blowing agents, HFO is the clear winner. The name HFO stands for hydrofluoroolefin, and like HFCs, the chemical features the same hydrogen, fluoride and carbon atoms. However, HFOs have zero Ozone Depletion Potential (ODP) and a low global warming potential. They have a shorter atmospheric lifespan, which is ultimately what makes them more environmentally friendly. By utilizing HFOs, you’ll be taking part in creating a healthier environment. In addition to having zero ODP and low GWP, features of HFOs include:

  • Low conductivity
  • Non-flammable material
  • No danger to the ozone layer
  • Nontoxic composition
  • Not considered as Volatile Organic Compounds (VOCs)

By choosing HFOs, you’ll reap benefits such as:

  • Sustainability – As mentioned above, HFOs have a low GWP, and they provide energy efficiency, offering further environmental benefits.
  • Safety – HFOs have a low flammability risk and a low toxicity. When handled properly, HFOs vs. HFCs do not pose risk to the environment or human health at any point of the lifecycle.
  • Performance – HFOs perform better than typical refrigerants and industrial gases such as CO2.

While restrictions on HFCs are not in place in every state, more are likely to come, so transitioning from HFC to HFO blowing agents will save your business in the long run while contributing to a greener environment.
