The chemical name of polytetrafluoroethylene is PTFE (polytetrafluoroethylene). It has the highest chemical resistance and heat resistance, and can resist almost all aggressive substances. PTFE has low lubrication and high sliding speed. Wear resistance is usually low, and PTFE materials are prone to cold flow under pressure. JST Seals can produce PTFE fillers such as carbon fiber, graphite, bronz...

The temperatures involved with LNG happens to be at the point where many elastomers and polymer materials lose elasticity and begin to behave as brittle materials. Some seals may also experience dimensional fluctuations related to temperature changes, further increasing the likelihood of failure. If temperature fluctuations are periodic, problems related to cyclic stress will arise. Another issue ...

In the seals manufacturing process, it is essential to ensure the accuracy of dimensions. Only the correct size can ensure that the seals fit well with the equipment and avoid leakages and failures. Therefore, dimensional measurement becomes an essential job. Preparation before measurement Before you start measuring, you need to do some preparatory work. First, clean the surface of seal to remove ...

Spring Energized Seals are made up of two components: a polymer-based seal jacket and spring energizer. Spring energized seals are great for use in environments that are too aggressive for other types of seals, as they provide a longer service life, maintain sealing pressure, and offer extreme wear resistance. Spring Energized Seals are popular in the medical device industry for a variety of reaso...

Grooves and Glands The physical space occupied by the seal is usually referred to as a groove, but it can also be referred to as a gland. In most cases, it’s a rectangular groove cut into the hardware whether it be on a piston, in the housing for a rod, or in the face of two mating surfaces. Compared to O Ring and elastomer seals, PTFE and polymer seals are critically dependent on hardware conditi...

FKM – Fluoroelastomers FKM is a fluorocarbon rubber, commonly referred to as fluorine rubber, VITON and FPM. They provide additional heat and chemical resistance. FFKMs are perfluororelastomer compounds containing an even higher amount of fluorine than FKM fluoroelastomers. They have improved resistance to high temperatures and chemicals and even withstand environments where Oxygen-Plasma are pres...
