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, bronze, glass fiber, carbon or MoS₂. Polyimide, mineral fiber, we also have virgin PTFE.

PTFE sealing is a highly cost-effective choice for high-performance sealing.

PTFE has a wide range of applications, it can make as hydraulic seals, PTFE gaskets, wellhead equipment seals, valves sealing, downhole tools sealing and PTFE rubber diaphragms, etc.
