What Are the Benefits of Using ePTFE?

Views:100     Author:Site Editor     Publish Time: 2021-08-02      Origin:Site

Polytetrafluoroethylene (PTFE) is an important variety of high molecular polymers. Because of its special carbon-fluorine bond polymerization effect, it has the characteristics of low friction coefficient, good self-lubricating performance, excellent chemical resistance and wide temperature range. Once it came out, it attracted great attention from all walks of life. It is widely used in medical, dental, aerospace, food and beverage industries, pharmaceuticals, telecommunications and other different industries. Its related products include heavy duty plumbers tape, PTFE tape on natural gas fittings, PTFE tape on hydraulic fittings and PTFEe cable wrape tape, etc.

 

ePTFE is a perfluorinated polymer with excellent physical and chemical properties. ePTFE can be made into sheets, rods or tubes of almost any size. Customizing ePTFE of various densities is now also very practical. According to its superior physical and chemical properties, related applications also include expanded PTFE membrane, expanded PTFE cable wrapping tape and expanded PTFE sealing tape.

Thin ePTFE membrane has excellent characteristics such as high chemical stability, high and low temperature resistance, corrosion resistance, weather resistance, high lubrication, good non-adhesion, electrical insulation, and good biocompatibility. It is an excellent waterproof, dustproof and breathable material. Due to its special properties in acoustic, electrical, magnetic, thermal and other aspects, ePTFE membranes and their components have been widely used in automotive, consumer electronics, new energy, medical, clothing, industrial filtration, aerospace and other fields.

 

Benefits of Using ePTFE

 

The advantage of ePTFE lies in its versatility. This material has many uses in different industries and fields. ePTFE has made some achievements in manufacturing and engineering. Non-woven fabrics and open-cell fluoropolymer plastics are suitable for medical applications and other key industries.

 

The physical and chemical properties of ePTFE may be critical for various medical and non-medical applications. These applications are mainly in the form of tubes, rods, sheets and special profiles. Specifically, its uses include implantable barrier membranes, instrument covers, delivery tubes, and so on. Few nonwoven plastics can meet or exceed the barriers of typical medical implants and industrial devices, the bending properties required for device delivery and bending parts. ePTFE is cited in medical research papers for its endothelialization and thrombosis properties.

The waterproof dust-proof and breathable ePTFE membrane is a functional material made by special manufacturing processes such as stretching. The manufacturing process of ePTFE is mainly to first polymerize the monomer tetrafluoroethylene to form the polymer polytetrafluoroethylene (PTFE), namely Teflon. Then the PTFE is made into porous waterproof, dustproof and breathable membrane materials with different pore diameters through processes such as stretching. The waterproof, dust-proof and breathable EPTFE membrane has a certain dust-proof function due to its special microstructure, and it can also have a certain oil-proof ability through surface treatment.

 

High-quality ePTFE materials have been applied in some parts of automobiles. ePTFE has the functions of balancing internal and external pressure differences and water vapor transmission, which can effectively improve the performance and service life of electronic products.

 

Due to its high temperature resistance, hydrophobicity, chemical inertness and high lubricity, ePTFE is used for high temperature sensor covers, low pressure key fluid channels, high temperature gaskets and chemical barriers. The soft and porous ePTFE can permeate air, but is still watertight under low pressure.
