Abstract

<div notation="docdba" type="abstract" xml:lang="en"><p>A thermoplastic composition includes: from 48.9 wt% to 93.9 wt% of a thermoplastic resin component including polypropylene, polypropylene copolymer, blends thereof or combinations thereof; from 5 wt% to 50 wt% glass fiber; from 1 wt% to 30 wt% impact modifier; and from 0.1 wt% to 10 wt% of a polyolefin-siloxane copolymer. The thermoplastic composition has a dielectric constant (Dk) of less than 2.8 at from 1-5 gigahertz (GHz) and a dissipation factor (Df) of less than 0.003 at from 1-5 GHz, the combined weight percent value of all components does not exceed 100 wt%, and all weight percent values are based on the total weight of the composition. Articles including the thermoplastic composition - and in particular telecommunications devices including the thermoplastic composition - are also described.</p></div>
