PTFE Rotary Lip Seal Design
When choosing a metal-cased rotary lip seal, you have many options. One design choice to be made is
what material to use for the lip. Most rotary shaft seals have a lip that is made of a thermoplastic (such as PTFE, PP, or PVC), an elastomer (natural or synthetic rubber), a thermoplastic elastomer (for example, PE), or a metal. In this post, we are going to look at what makes PTFE a competitive choice for a metal-cased rotary lip seal by investigating six things your competitors dont want you to know.
Here are some additional blog posts here at Advanced EMC Technologies on polymer seals:
The primary purpose of a typical expansion bellows is to isolate a fluid from neighboring components. Bellows are used in a variety of applications, including pulse dampeners, HVAC systems, pharmaceutical processing, pollution control, and piping systems.
