Polytetrafluoroethylene
Key Features
● Outstanding high-temperature resistance, chemical stability, and electrical insulation properties.
● Low dielectric constant and low dissipation factor, ensuring minimal signal attenuation and insertion loss in high-frequency RF applications.
Key Differences
While PTFE excels in high-frequency applications, its mechanical strength is relatively low, making it prone to deformation under compression and pressure. Therefore, it may not be suitable for high-pressure or high-stress environments.
Performance Characteristics
● Physical Properties: Low friction coefficient, high melting point, excellent wear resistance, and corrosion resistance.
● Thermal Properties: Exceptional thermal stability, maintaining performance at elevated temperatures.
● Chemical Properties: Superior chemical resistance, remaining stable against most chemicals.
● Electrical Properties: Low dielectric constant and loss factor, along with excellent insulation performance.
