ePTFE 100% Virgin Customized Tubing OEM Manufacturer

Product Description：

Extruded PTFE (ePTFE) tubes are manufactured through a complex process that involves blending PTFE fine powder resin with an extrusion aid, followed by extrusion through a die to define its profile. The extruded material is then stretched under heat to achieve a soft, marshmallow-like texture. The stretching parameters play a crucial role in determining the final characteristics of the ePTFE, including texture and porosity.

Applications of ePTFE tubes are diverse due to their unique properties. The texture is favored for gasket materials, while porosity is utilized in membranes and filter applications. The porosity allows gases and vapors to pass through while blocking liquids, making ePTFE ideal for venting and high-end filtration applications. It ensures leak-proof systems while allowing excess gases to escape and prevents water from entering electronic enclosures while evacuating accidental moisture buildup.

Advantages of ePTFE tubes include the combination of texture and porosity, making them highly flexible and resistant to kinking, unlike regular PTFE tubes. They are suitable for systems requiring liquid passage and vapor expulsion. ePTFE tubes find applications in chemical and medical fields, including surgical grafts and stents, in addition to automotive uses.

Despite the challenges in manufacturing ePTFE tubes, overcoming these difficulties results in a versatile and highly effective product with a wide range of applications.
