Beschreibung
Zusammenfassung:	A fiber-reinforced polymer composition comprising from about 60 wt. % to about 90 wt. % of a polymer matrix that contains a propylene polymer and from about 10 wt. % to about 40 wt. % of a plurality of long reinforcing fibers that are distributed within the polymer matrix, is provided. The polymer composition exhibits a dielectric constant of about 4 or less and dissipation factor of about 0.01 or less at a frequency of 2 GHz. Further, the polymer composition exhibits a Charpy unnotched impact strength of about 20 kJ/m2 or more as determined in accordance with ISO Test No. 179-1:2010 at a temperature of about 23° C., and a Limiting Oxygen Index of about 25 or more as determined in accordance with ISO 4589:2017.
