Summary

The excellent properties of low moisture absorption, electrical performance stability, and chemical inertness of PTFE make it very suitable for data transmission cables that require low attenuation. As one of the lowest dielectric constants of organic materials, it will be widely used in the 5G communication field in areas such as base station filter high-frequency high-speed PCB/FPC, 5G chip process, and high-frequency connectors, cables, etc.

Electronic and Electrical

The dielectric constant of PTFE is relatively small, so it can be used to prepare enameled wires, which can be used in miniature motors. PTFE glass-coated fabric and glass fabric are used to make high-temperature, high-frequency insulating materials, which can be used in satellite communication and computer applications: PTFE film is used to make capacitors, as an insulating layer, cushion, cable, etc. for instruments; different-diameter PTFE thin-walled tubes are used as insulating sleeves, heat-shrink tubes, spiral tubes, and insulating water-inlet tubes for generators.

1. Insulation layer of wires and cables: PTFE's high insulation properties make it an ideal material for wire and cable insulation, effectively preventing current leakage and ensuring safe use. For example, Danke's PTFE heat shrink tubing can be used as an insulating material for wires.
2. Circuit board substrate: The high temperature resistance and stable electrical properties of PTFE make it an ideal choice for high-frequency and microwave circuit board substrates.
3. Capacitors: The low dielectric constant and low dielectric loss of PTFE film make it an ideal material for making capacitors, which perform well in communication and radar equipment.
4. Other electrical components: PTFE is also suitable for making insulating washers, electrical connectors, and other components that require excellent electrical properties and corrosion resistance. PTFE perfectly meets these requirements.

5G is a network that can meet the explosive data demand at any time and place. In mobile and fixed networks, 5G wireless networks will use high-frequency transmission technology. To achieve high-frequency transmission, it is necessary to use low dielectric constant and low dielectric loss materials. The excellent properties of low moisture absorption, electrical performance stability, and chemical inertness of polytetrafluoroethylene make it very suitable for low-attenuation data transmission cables. As one of the lowest dielectric constants of organic materials, it will be widely used in the 5G communication field in areas such as base station filters, high-frequency high-speed PCB/FPC, 5G chip process, and high-frequency connectors and cables. The PCB of the 5G mobile phone motherboard uses a high-frequency copper-clad laminate based on PTFE to reduce signal loss. The high-frequency signal transmission between the RF module and the antenna module of the 5G mobile phone is completed through PTFE fine-pitch RF coaxial cable, ensuring low loss of high-frequency high-speed signals in the mobile phone.
