Regular maintenance is a good way to keep tools and machines up and running. However, when you’re doing maintenance work more often than usual, is it still possible to keep the current units in working condition? Jorge Sastre, an engineering professor from the European University of Madrid, discusses this question in his article for Bearing-News.com.
Advanced EMC Technologies’ Teflon PTFE seals are one of their frontline products, in continuous demand across many industries. The seal offers perfect static and dynamic sealing for the most demanding applications. Other key features include low friction, chemically resistant, dry/lubricated running used in many industries such as fluid handling, semiconductor, aerospace and instrumentation..
Talking about it, a senior executive with the company said, “The component is an integral part of the equipment across industry sectors. It can withstand extreme temperature, chemicals and pressure. Sealing jacket is made of resilient PTFE and can be energized by an internal spring when needed which applies a load to the sealing element at low pressures. It has unlimited shelf life and controlled friction/load.”
Spring energized seals have a resilient seal jacket and compensates for jacket wear, hardware misalignment or eccentricity. Polymer seal jackets materials include Virgin PTFE, Carbon/Graphite PTFE, Moly/Filled PTFE, Glass/Moly PTFE, Polyimide/Filled PTFE, UH/Polymer PE, 60% Bronze / filled PTFE and PCTFE / KEL F. FDA approved low friction Virgin PTFE is excellent for light duty service, cryogenic applications and low molecular weight gas service.
Carbon/Graphite PTFE offers superb resistance to heat and wear. Good in liquids and steam, it is recommended for dry or semi-dry applications. The executive added for Glass/Moly PTFE, “It works well for high pressure applications and is impressive in hydraulic, steam and water. The material is abrasive in rotary service against soft metals.”

Polyimide/Filled PTFE seals are outstanding in dry service with low wear rate in vacuum and inert gases. It has very low abrasion to dynamic mating surfaces. UH/Polymer PE has higher friction than PTFE compounds. Static and slow dynamic PCTFE / KEL F is best grade for cryogenic applications. 60% Bronze / filled PTFE excels at very high rotary speeds with low pressure.
