Latest Patents

One of Donald Goffena's latest patents features a thin-wall PTFE tube. This invention is specifically designed as a tube made from porous expanded PTFE film. The unique microstructure of the porous PTFE film contains multiple fibrils that are oriented substantially parallel to one another. Notably, the tube's wall thickness is less than approximately 0.25 mm and is constructed from at least one first layer and one second layer of the porous PTFE film. The fibrils in these layers are oriented substantially perpendicular to each other, enhancing the structural integrity and performance of the tube. The first layer's fibrils are aligned parallel to the longitudinal axis of the tube, while the second layer’s fibrils are arranged circumferentially. This arrangement can be reversed based on the design needs, and both layers may be reinforced with components such as a braid or a helically-wrapped metal wire positioned between them.
