Ethylene tetrafluoroethylene (ETFE)
ETFE, or Tefzel© cable ties are highly resistant to chemical corrosion, gamma radiation, ultraviolet radiation, and radioactive exposure. This makes the material suitable even for use in nuclear power plants. In addition to these properties, it is also highly resistant to high temperatures – up to 170 °C.
What is Ethylene Tetrafluoroethylene (ETFE)?
Ethylene tetrafluoroethylene is better known by the brand name Tefzel©. It is a thermoplastic polymer that offers excellent resistance to external influences, including:
- Thermal influences: Tefzel® can withstand temperatures up to 170°C
- Mechanical influences: Tefzel® is highly resistant to damage from friction, for example
- Chemical influences: Tefzel® resists chemicals, including acids and salts
Tefzel® was introduced to the market by DuPont in 1972.
Properties of Ethylene Tetrafluoroethylene (ETFE)
Cable ties made from ETFE are resistant to temperatures ranging from -40°C to +170°C (150°C for the WKK version). They comply with flammability classification UL 94 V-0 and are halogen-free. As mentioned above, they offer excellent resistance to chemicals and have good electrical (insulating) properties.
Tefzel® meets UL, REACH, RoHS, and CE standards.
Types of Ethylene Tetrafluoroethylene (ETFE) cable ties
Our range includes two types of cable ties made from ETFE:
- WKK – Plastic cable ties – Resistant to chemicals, radiation, and extreme temperatures (up to 150°C) – Tefzel®
- Ty-Rap® – Plastic cable ties – Stainless steel lock – Resistant to chemicals, radiation, and extreme temperatures (170°C) – Tefzel®
Both types of cable ties share most of the same properties, with two main differences. The Ty-Rap® version has a stainless steel locking barb, whereas the WKK version uses a plastic locking barb. Additionally, the Ty-Rap® cable tie is resistant to temperatures up to 170 °C, while the WKK version is rated up to 150 °C.
Applications of Ethylene Tetrafluoroethylene (ETFE)
Thanks to its excellent properties, Tefzel® can be used in a wide range of environments and industries. These cable ties are commonly used in nuclear power plants, laboratories, and other settings where a strong cable tie is needed that can withstand a variety of extreme environmental conditions.
