A fiber-reinforced polymer composition that contains a polymer matrix and a plurality of long reinforcing fibers that are distributed within the polymer matrix is provided. The polymer matrix contains a propylene polymer and constitutes from about 30 wt. % to about 90 wt. % of the composition. The fibers constitute from about 10 wt. % to about 70 wt. % of the composition. Further, the polymer composition exhibits a spiral flow length of about 450 millimeters or more as determined in accordance with ASTM D3123-09 and a volatile organic content of about 100 micrograms per gram or less as determined by VDA 277.

High flow fiber-reinforced propylene composition having low emissions

A fiber-reinforced polymer composition that comprises a polymer matrix that contains a propylene polymer is provided. The polymer matrix constitutes from about 30 wt. % to about 80 wt. % of the composition, and a plurality of long reinforcing fibers that are distributed within the polymer matrix. The fibers constitute from about 20 wt. % to about 70 wt. % of the composition. The polymer composition exhibits a spiral flow length of about 450 millimeters or more as determined in accordance with ASTM D3123-09, and after aging at a temperature of 150&#xb0; C. for 1,000 hours, a Charpy unnotched impact strength greater than about 15 kJ/mas determined at a temperature of 23&#xb0; C. in accordance with ISO Test No. 179-1:2010.
