Flexible PTFE sheet is formed through an expansion process that gives PTFE a soft, conformable structure capable of sealing uneven flange surfaces under low bolt loads, making it a reliable choice where traditional rigid PTFE sheets cannot achieve full surface contact.

The flexible PTFE sheet is a refined form of PTFE engineered through a controlled expansion technique that reorganizes the material into a multidirectional, fibrillated structure. This transformation produces a sheet that retains the chemical inertness of conventional PTFE while gaining far superior flexibility, compressibility, and recovery. Unlike dense skived PTFE, the expanded version adapts instantly to surface irregularities, making it highly effective in applications involving worn flanges, delicate coatings, glass-lined assemblies, or components that cannot tolerate high bolt stress.
Machining and fabrication are straightforward: the sheet can be cut into rings, strips, or custom gaskets without producing fibers or particulates, ensuring clean integration into pharmaceutical, food, semiconductor, and chemical systems. Its ability to deform uniformly under minimal torque makes it suitable for FRP flanges, enamel-coated connectors, and aging equipment where bolt tension must be controlled to prevent structural damage.
In pipelines, reactors, mixers, compressors, vacuum chambers, and precision fluid-handling units, the flexible PTFE sheet delivers long-term sealing performance while maintaining the ultra-low friction, non-aging behavior characteristic of PTFE materials.
