Hytrel (a DuPont product) is a thermoplastic polyester elastomer, sometimes referred to as TPE, that combines in one product the elasticity of rubber with the strength and performance characteristics of an engineering thermoplastic. It can be found in applications such as:

In order to get a good understanding of the potential uses for PTFE energized seals, this blog post will take a look at three specific areas these seals are commonly used:

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.

Food processing is one of the most heavily regulated industries. The selection of bearings and bushings for the food industry can be tough, especially when it comes to MRO.
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.
Whether it’s a labyrinth seal used in a compressor or a spring-energized seal used in a cryogenic application, seal performance is critical. Premature failure of seals is simply not acceptable, but there are ways to prevent these problems. In this blog post, we are going to discuss material selection, wear sleeves, lubrication, and optimized seal design as options for improving the performance of your seals.
