When high-temperature performance is not a major concern, PPS can serve as a viable and economical alternative to PEEK. In this blog post, you will learn how these high performance engineering polymers are similar and where they differ (besides the price).
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.
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.
Sealing in a cryogenic environment is hard enough, but when it involves fluids that are being stored or processed near their boiling point, it opens up a whole new set of challenges.
One of the critical components of a ball valve is its seat material.
Spring-energized seals can solve quite a few problems for MRO (maintenance, repair, and operations) in the food processing industry. Many of the seals used in food processing are mission critical, and a failed seal can cost much more than just repairs and downtime because it can result in contamination.
