2019 EPA Changes to Refrigerants: Seal Material Considerations – Part 2

 

In our last post on the subject of the 2019 EPA changes to refrigerants, we pointed out that the HVAC and refrigeration industries faced three specific design challenges as traditional refrigerants are phased out starting in 2019: efficiency, chemical compatibility with seals, and reducing leaks. Fortunately, there are seal solutions and polymer materials that can address all three of these issues — which happens to the topic of this blog post.

2019 EPA Changes to Refrigerants: Reasons and Impacts on HVAC Design – Part 1

Between the 1990s and 2010s, society became much more aware of environmental issues, including the ozone layer and climate change. The leakage of refrigerants has been found to contribute to ozone layer damage and unhealthy HFC levels. Because of such issues, there has been a greater drive to develop more environmentally friendly refrigerant options and find new ways to minimize refrigerant leakage.
