PTFE Spring-Energized Cryogenic Seals Revisited

Posted On January 29, 2016

Cryogenic Seals

Cryogenic seals must not only handle unbelievable low temperatures, but also perform under high pressure conditions.  If you aren’t familiar with cryogenic seals, a cryogenic seal is a special type polymer seal used with media at temperatures below -238°F and down to -460°F (absolute zero).  Cryogenic seals can be found in a variety of industries, from LNG compressors and loading arms in the petroleum industry to rocket propulsion systems in the aerospace industry.

PTFE & UHMW PE Seals: 3 Benefits for Food & Dairy Industry

Posted On January 08, 2016

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?

Here are some other articles on advanced polymers in the food and dairy industry from Advanced EMC Technologies:

Six Kinds of Polymer Jacket Materials for Spring-Energized Seals

Posted On August 04, 2015

Spring-Energized Seals Jacketing Material



When selecting a jacketing material for a spring-energized seal, engineers look at the

  • operating temperature,
  • pressure (including whether or not it is static or cyclic),
  • dynamic conditions,
  • media involved,
  • amount of seal squeeze,
  • and the geometry involved
In this article, we are going to look at some of the options out there for a polymer jacketing material.
