WebAug 27, 2024 · FEP lacks the regularity in polymer structure that PTFE has, and thus does not crystallize as readily. Since the crystallite density is lower, the polymer is more amorphous and the medium does not scatter as much and thus appears more transparent. The transparency of a plastic does not depend on its nature but on how it is made. Webshows a comparison of woven glass/PTFE, microfiber glass/ PTFE and CuFlon’s dielectric in reference to moisture ab-sorption. It can be seen that both the woven glass/PTFE and microfiber glass/PTFE absorb moisture while CuFlon’s dielectric has less than .01% absorption. This is because of its uniform, pure PTFE structure. 4) Anisotropy
WebMay 27, 2009 · PTFE-based composites are widely used for the fabrication of microwave circuit boards [3], [4]. PTFE has low dielectric constant ε ′ r ∼ 2.1 and extremely low loss tangent tan δ ∼ 0.0003 which is stable over a wide range of frequencies [5]. The low loss tangent is a consequence of the symmetrical conformation of the polymer backbone ...
