摘要: A polymer composition includes: from about 20 wt. % to about 80 wt. % of a polymer base resin; from about 10 wt. % to about 60 wt. % of a thermally conductive filler; and from about 5 wt. % to about 60 wt. % of a dielectric ceramic filler having a Dk of at least 20 when measured at 1.1 GHz or greater. The polymer composition exhibits a dielectric constant greater than 3.0 at 1.1 GHz when tested using a split post dielectric resonator and network analyzer on a sample size of 120 mm by 120 mm and 6 mm thickness according to ASTM D150. The polymer composition exhibits a dissipation factor of less than 0.002 at 1.1 GHz when tested using a split post dielectric resonator and network analyzer on a sample size of 120 mm by 120 mm and 6 mm thickness according to ASTM D150.

摘要: Provided are extrusion dies having entrance, orientation, merging (205), and exit (211) sections, which dies may be used to produce fibers having, e.g., oriented reinforcement materials (e.g., PTFE) dispersed within. The dies provide fibers having enhanced mechanical and processing properties. The orientation section comprises orientation channels (203) wherein a ratio of a cross-sectional area having of the channel inlet to a cross-sectional area of the channel outlet is between 2 and 45.
