PTFE is one of the most critical dielectric materials. Thanks to its ultra-low dielectric constant, extremely low dielectric loss, and excellent thermal stability, PTFE is widely used in 5G communication systems, millimeter-wave radar, satellite communication, aerospace electronics, and microwave RF modules. Among all its physical properties, the melting point of PTFE is one of the most important parameters, as it directly affects PCB manufacturing processes, thermal reliability, and long-term performance stability.
