expanded PTFE (ePTFE)
expanded PTFE (ePTFE) is a specially processed Type of Polytetrafluoroethylene (PTFE).
By orientating the PTFE molecule fibres in a special production process, the
material gets improved tensile strength and creep resistance, compared to standard not expanded PTFE.
Molecule fibres of monodirectional ePTFE are beeing orientated in one single direction.
Whereas multidirectional ePTFE is beeing orientated in several directions. With this a complex fibre structure is built up, which gives
the material its unique strength and creep resistance in longitudinal and transverse direction.
