If you are looking for high-quality wires that meet the latest 2025 UL1332 standard, learn about our FTP nickel-plated Teflon wire products, which comply with the latest regulations and can effectively help your products pass market compliance tests.
If your products use Teflon wire and are exported to the United States, Europe, or Japan, please pay special attention! Since November 2024, UL1332 standards have switched from tin-plated to nickel-plated copper wire. Going forward, using tin-plated copper wire will no longer comply with the UL1332 standard.
Teflon (PTFE) conductors with tin-plated copper wire release harmful fluorinated compounds (e.g., PFAS chemicals) when exposed to high temperatures or heat. These compounds are considered environmental pollutants and may have long-term health effects. International regulations have banned their use, and strict restrictions have been imposed in regions like the United States, the European Union, and Japan.
According to SGS data, the PFAS chemical family is wide-ranging and includes perfluorocarboxylic acids (PFCA), perfluorooctanoic acid ammonium (PFOA), and their derivatives, such as polytetrafluoroethylene (PTFE), commonly known as Teflon.
Therefore, UL updated the UL1332 standard in November 2024 to replace tin-plated copper wire with nickel-plated copper wire.
You only need a simple magnet for the test! If the magnet sticks to the wire, it's nickel-plated; if it doesn't, it’s tin-plated.
Advantages: Low cost, good conductivity, excellent solderability.
Disadvantages: Poor corrosion resistance and high-temperature performance.
Advantages: Better corrosion resistance, oxidation resistance, high-temperature endurance, and wear resistance.
Disadvantages: Higher cost, poorer solderability.
This change will affect many exported products, so make sure your products meet the latest standards to avoid market difficulties or losses due to non-compliance.
