Tubo de ePTFE 100% Virgem Personalizado Fabricante OEM

Product Overview

Flexible microporous ePTFE tubes in standard and custom dimensions

Yozonetech supplies expanded PTFE tubing for applications that require a flexible fluoropolymer tube with a porous structure. Expanded PTFE, or ePTFE, is produced from PTFE resin by special processing that includes stretching. Connected microfibers form a network containing numerous pores, giving the material a soft, flexible and resilient structure.

Choose from the complete 34-entry size list below or send a drawing for review of a custom tube. Specify the bore, outside diameter, finished length and the permeability or sealing behavior required by your application.

Product Benefits

Flexible microfiber structure

The white expanded material has a network of fine connected fibers and pores that allows it to bend freely. Select dimensions and support against the intended installation and handling requirements.

Resistência química

ePTFE provides resistance to many chemicals. Evaluate the exact medium, concentration and temperature together with the tube’s porous construction and intended duty.

Thermal and wear performance

Expanded PTFE is used where high- and low-temperature resistance and wear performance are useful. Confirm the finished tube’s temperature limits and mechanical requirements for the selected grade and geometry.

Application specific porosity

The porous material structure can support permeability-related applications. Specify the required pore characteristics, gas flow, water resistance or sealing behavior; these cannot be inferred from tube diameter alone.

Technical Specifications

Expanded PTFE is also produced in membrane, gasket, sheet or plate, and tape forms. Those forms have their own specifications; the tube dimensions below describe this tubular product range.

Complete ePTFE Tube Size Table

All pairs are in mm. Each pair retains the larger-diameter-first order of the supplied size list, presented here as OD × ID. Confirm diameter designation, tolerances and the measurement condition for the flexible tube with the production drawing.

The table includes all 34 listed sizes. Blank cells are unused positions. The 13.35 × 7.35 mm and 16.52 × 10.52 mm entries retain their exact stated precision. Additional sizes can be reviewed.

Dimensional and Functional Selection

Specify outside diameter, inside diameter, wall thickness, finished length and tolerances separately. Nominal wall thickness can be calculated as (OD − ID) ÷ 2, but the supplied tube’s acceptance limits and measurement method must be agreed for its soft porous structure.

Define whether the application requires gas permeability, filtration, a water barrier, sealing or another function. Provide the medium, temperature, differential pressure or vacuum and any movement requirements. Porosity, pore size, density, flow performance and liquid breakthrough pressure need product-specific confirmation.

The material’s flexibility and resistance to chemicals do not establish a pressure rating or a liquid-tight wall. Where liquid transport or sealing is intended, confirm wall performance, end connections and the complete assembly before selecting the tube.

Custom ePTFE Tubing

Send a drawing or specify OD, ID, wall thickness, length, quantity and dimensional tolerances. Include required porosity or permeability, test conditions, cleanliness, packaging and any documentation requirements. We will review the tube geometry and functional specification together.

Agree inspection criteria for tube dimensions, wall uniformity, surface condition and any permeability, liquid-barrier, pressure, leak or cleanliness test. Define material and finished-product qualification requirements for specially regulated applications.

Applications of Expanded PTFE

Expanded PTFE is used across several product forms. The applications below describe the material family; tube suitability depends on the selected construction and qualification.

Industrial filtration

Material uses include heavy-metal filtration of electroplating wastewater, shield-tunneling construction wastewater treatment, PCB sludge reduction filtration, metal waste-acid and wastewater filtration, and oilfield reinjection-water treatment. A tube application requires separately specified pore and flow performance.

Sealing and industrial liquid handling

Expanded PTFE gasket and sealant forms are used where chemical, wear and thermal resistance are required. For a tube used in liquid transport or sealing, confirm the fluid-barrier behavior, pressure duty and connection design.

Electronic and dielectric applications

Expanded PTFE material is used with copper-core and fiber-optic cables, cable systems, PCB materials, conductive interface products and shielding gaskets. Related sectors include telecommunications, computers, test and measurement, defense, aviation and aerospace. Define the exact electrical or shielding requirement for the finished part.

Membranes fabrics and medical material forms

Expanded PTFE membranes are used in lightweight, durable, waterproof and windproof fabrics with different permeability levels. Specialized material forms are also used for artificial blood vessels and heart patches. These uses require their own finished-product qualification and do not establish approval for the industrial tube range.

Frequently Asked Questions

How is ePTFE different from standard PTFE tubing

ePTFE is expanded to form a porous microfiber network. Its porosity and flexible structure are key selection factors, while the exact flow and barrier behavior must be specified for the finished tube.

Are all ePTFE tubes waterproof and breathable

No single barrier or airflow rating applies to the entire range. Specify the required permeability and water or liquid resistance, including the pressure and test conditions.

Can you supply custom tube sizes

Yes. Send OD, ID, length, tolerances and quantity, together with the required functional properties and documentation.

What temperature and pressure can the tube withstand

Confirm the limits for the exact grade, geometry, porosity and assembly. No single numerical temperature or pressure rating is assigned to the complete size range.
