Extrusion of PTFE resin combined with a lubricant produces expanded PTFE grafts. The nanopores structure of ePTFE is achieved using a high-temperature process that involves fast flexing of the extruded tube. Porosity is a key element in determining how well a prosthetic graft heals and integrates with the surrounding tissue. The spacing between the nodes determines the degree of porosity of an ePTFE graft. Expanded PTFE (ePTFE) tube is air-permeable because it is microporous, making it ideal for any application that requires a permeable material. As a result, ePTFE differs from traditional PTFE. To the touch, the materials are soft and flexible, and it is like a smooth, spongey marshmallow. Expanded PTFE is commonly utilized as wire, sealing tape, and tubing. These expanded PTFE materials by JD Jones are made using quality raw materials.
