20 Claims

1. An antenna housing comprising a polymer composition, wherein the polymer composition comprises a thermoplastic polymer, glass fiber and an inorganic filler,

wherein the thermoplastic polymer is a heterophasic propylene copolymer consisting of a propylene-based matrix and a dispersed ethylene-α-olefin copolymer, the heterophasic copolymer comprises between 70 and 90 wt % of the matrix and between 10 and 30 wt % of the dispersed phase,

wherein the inorganic filler is present in an amount of 2 to 20 wt % of the total polymer composition, and the total amount of glass fiber and the inorganic filler is from 21 to 50 wt % of the total polymer composition,

wherein a ratio between the weight of glass fiber and the weight of the inorganic filler is from 1.0 to 16.0, and

wherein the heterophasic propylene copolymer is present in an amount of 10 to 60 wt % of the total polymer composition.
