Automotive PTFE Shaft Seals
In this article, we are going to explore the reasons why PTFE seals are among the best choices for many automotive applications. You’ll find PTFE seals in fuel cell seals, fuel injection pumps, steering wheel seals, air conditioning, compressor seals, hydraulic seals, and more. We’re going to focus our attention on PTFE shaft seals. Let’s take a look!

PTFE Rotary Shaft Seals Outperform Rubber Shaft Seals
Elastomeric seals performed well for many years, but as the applications and environments became more demanding, elastomers had a hard time keeping up. If the application pressure is above 30 psi or the operating temperature goes above 275°F, elastomers simply don’t perform as well as, say, PTFE. (polytetrafluoroethylene). In this article, we are going to look at 3 areas where PTFE rotary shaft seals outperform rubber shaft seals.

PEEK Increasingly Popular
Polymer bushings have found widespread acceptance because they are typically low friction, light weight, relatively inexpensive, have an extended service life, and can be self-lubricating. Most polymer bearings and bushings are made from a form of PEEK, PTFE, Nylon, or UHMW PE. PEEK is becoming increasingly popular because it offers a good balance of chemical, heat, and wear resistance; and is, versatile when it comes to manufacturing.

The PTFE & UHMW Challenge
The medical and pharmaceutical industries face tough challenges when it comes to sealing solutions. In this article, we are going to talk about how spring-energized PTFE and UHMW seals can help with three of those challenges.

Extremely Efficient Sealing System
Spring-energized seals are an effective sealing solution for both dynamic and static applications. The sealing element itself achieves a seal at low pressures, and when pressures increases the seal is made tighter as the spring engages. The spring also compensates both for eccentricity and wear on the seal jacket, and increases the natural resilience of the seal jacket. This results in an extremely efficient sealing system.
When PTFE and UHMW materials are used for the seal jacket, you have a spring-energized seal that performs with distinction under high pressures, in extreme temperatures, has ultra low friction, and is quite chemically inert. So what does the mean for the food and dairy industry?
