Polytetrafluoroethylene sheet (also called PTFE sheet, Teflon sheet, Teflon sheet) is divided into two kinds of molding and turning, molded sheet is made of PTFE resin by molding method at room temperature, and then sintered and cooled. PTFE turned sheet is made of PTFE resin by pressing, sintering and rotary cutting. Its products are widely used and have excellent comprehensive performance: high and low temperature resistance (-192°C-260°C), corrosion resistance (strong acid, strong alkali, aqua regia, etc.), weather resistance, high insulation, high lubrication, non-adhesion, non-toxicity and other excellent characteristics.
Dielectric Constant of F4B Sheet
The dielectric constant of F4B sheet refers to the dielectric properties of the material under the action of electric field, that is, the ratio of electric field strength and potential shift.F4B sheet is a high-performance polytetrafluoroethylene material, with excellent corrosion resistance, high temperature resistance, abrasion resistance, and insulating properties, so it is widely used in the field of electronics, chemical industry, aerospace and other fields.
The dielectric constant of F4B sheet is one of the most important indicators of its insulating properties. The smaller the dielectric constant, the better the insulating properties of the material. F4B sheet has a dielectric constant between 2.1 and 2.3, which is much lower than that of general polymer materials, and therefore has excellent insulating properties. Under high frequency electric field, the dielectric constant of F4B sheet is even lower, which can effectively reduce the interference and loss of electromagnetic wave to ensure the stability and reliability of electronic equipment.
In addition to insulating properties, F4B sheet dielectric constant also affects its application in the field of microwave microwave signals in the transmission process will be affected by the medium, the smaller the dielectric constant, the faster the signal transmission speed, the smaller the transmission loss. Therefore, the low dielectric constant of F4B sheet makes it an ideal material for microwave circuits, antennas, filters and other microwave devices.
The dielectric constant of F4B sheet is one of the most important indicators of its insulation and microwave performance. Low dielectric constant makes it has excellent insulation properties and microwave performance, widely used in electronics. Chemical industry, aerospace and other fields. With the continuous development of science and technology, the dielectric constant of F4B sheet will continue to be optimized to provide better support for the development of various industries.
