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...
Industrial grade FFKM seal FFKM has excellent chemical corrosion resistance and high temperature resistance characteristics, which makes FFKM widely used in various harsh working conditions for chemical applications. Semiconductor grade FFKM seal JST semiconductor-grade FFKM compounds are with high purity (low amount of extractables) and very good oxygen and CF4 plasma resistance, which have the t...
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 ...
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 ...
JST new design of Lockdown screw packing is made from one PTFE ring and two copper rings. PTFE ring is able to lower the holding force and friction, thus lower the torque. Meanwhile, two copper rings can better protect the LDS body not to be damaged during the twisting and rotating process. JST has conducted the test to qualify the PR2 performance of 1.51 inch LDS packing seal at L-X -46℃~177℃ ( -...
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 medical device industry is facing evolving challenges in finding suitable sealing solutions for new and improved designs. We will focus on customizing spring energized PTFE seals as a potential solution to the sealing challenges in the medical industry. PTFE is a popular choice for spring energized seals used in medical applications for several reasons. One is that some grades of PTFE have bee...
The world we know of cannot be achieved without computers - these technologies cannot be achieved without semiconductors. However, as wafers become smaller and smaller, their production also faces unique challenges, with pollution posing greater risks to their integrity and functionality. One factor often overlooked in semiconductor manufacturing is the overall sealing process. Your seal will eith...
The Ring Type Joint was originally developed for high pressure/temperature applications in the petroleum industry, mainly used for drilling and completion equipment in oil fields. However, today, this product series can also be used for valves and pipework assemblies, as well as some high integrity pressure vessel joints. There are three types of ring type joint gasket designs, the R type, RX type...
