TFM is a modified PTFE (polytetrafluoroethylene), commonly known as white polytetrafluoroethylene. This material has excellent chemical properties and is the lowest friction coefficient among all solid materials. The wide temperature range (-200 ℃ to+260 ℃) and mechanical properties makes it a widely used universal material. TFM Modified PTFE has the same excellent chemical resistance and thermal ...
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 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...
Wear strips are suitable for guiding pistons and piston rods of hydraulic cylinders and pneumatic cylinders with supporting and guiding functions. We can provide double-sided embossed wear strips with a thickness equal to or greater than 2mm. The embossed structure facilitates the formation of lubricating micro-pits, improves micro-lubrication and protects the sealing system. Polyester resin fabri...
PTFE seal designs were developed to incorporate energizing elements such as O-Rings and metallic springs. These energizers ensure the PTFE seal is always in contact with the sealing surface. JST utilizes three different types springs to internally energize PTFE and other polymer seals, each with its own advantages. Below, we will discuss in details for some of the advantages of cantilever V-spring...
A needle valve seal is a component in needle valves, which are precision valves used to control the flow rate of liquids or gases in a system. The needle valve seal is responsible for preventing leakage through the valve and ensuring a tight seal. There are different types of seals used in needle valves, depending on the specific requirements of the application. Some common types of seals used in ...
Modified PTFE or TFM, is a high-density copolymerized material. It has low gas permeation and reduces cold flow. Often used in the medical field as an artificial blood vessel graft and in other applications where biocompatibility is required. TFM is also FDA and USP class VI suitable. TFM remains a largely unfamiliar material in the general PTFE machine parts and seal markets. At JST, we have...
Spring energized seals have been widely used in harsh working conditions such as extreme operating temperatures, high pressure, corrosive chemical media, low friction, and high operating speeds. The main materials for seal Jackets aremodified PTFE and other high-performance plastics. PTFE is a sealing material with superior chemical resistance and good heat resistance compared to perfluorinat...
