What is tefzel material?

What is tefzel material?

Tefzel™ ETFE (ethylene-tetrafluoroethylene) resins are melt-processable copolymers with a reputation for excellent physical toughness and resistance to radiation, chemicals, UV, and extreme temperatures.

What is tefzel coating?

The coating Tefzel™ is a modified ETFE (ethylene-tetrafluoroethylene) fluoroplastic available as pellets or as a rotational moulding powder. It is a thermoplastic that combines superior mechanical toughness with exceptional chemical resistance that approximates that of fluoroplastic resins Teflon™.

What is tefzel used for?

ETFE (ethylene tetrafluoroethylene) commonly referred to as Tefzel® is a modified copolymer of ethylene and tetrafluoroethylene. It has medium stiffness, which makes it suitable for applications such as chemical tank linings that require weldability and the ability to conform to curved metal or FRP surfaces.

Is tefzel a Teflon?

Tefzel fluoropolymers are melt-processible thermo- plastics. They are part of the DuPont family of fluorine-based products that includes Teflon® PTFE, Teflon FEP, and Teflon PFA fluoropolymer resins.

Is tefzel the same as ETFE?

Ethylene tetrafluoroethylene (ETFE) is a fluorine-based plastic. It was designed to have high corrosion resistance and strength over a wide temperature range. ETFE is a polymer and its source-based name is poly(ethene-co-tetrafluoroethene). It is also known under the brand name Tefzel.

What is tefzel wire?

Mil-Spec ETFE Insulated Electric Wire (MIL-W-22759/16-22) Tefzel® is a ethylene-tetrafluoroehtylene (ETFE) insulation. Tefzel® is light, thin, resistant to abrasion, fuel, most chemicals, cuts and oil. It’s designed for aerospace applications where dimensional tolerance, weight, and mechanical durability are required.

Is ETFE heat resistant?

ETFE has an approximate tensile strength of 42 MPa (6100 psi), with a working temperature range of 89 K to 423 K (−185 °C to +150 °C or −300 °F to +300 °F). ETFE resins are resistant to ultraviolet light.

Is tefzel halogen free?

Tefzel™ ETFE film is chemically inert and solvent-resistant to virtually all chemicals, except molten alkali metals, gaseous fluorine, and certain complex halogenated compounds, such as chlorine trifluoride, at elevated temperatures and pressures.

Is ETFE environmentally friendly?

More Efficient than Glass These measures include energy savings, emissions reduction, water efficiency and indoor environmental quality. ETFE film is safer and lighter in weight than glass, so it requires less structural support. This means buildings using ETFE use fewer heavy materials like steel.

What is the difference between PTFE and ETFE?

PTFE is constructed from carbon and fluorine atoms whereas ETFE is built from carbon, fluorine and hydrogen. Giving advantages to using both. The tensile strength of ETFE can be as much as 38% greater than PTFE, meaning ETFE material can be subjected to harsher operating conditions than its counterpart.
