Title:
HIGH FLOW FIBER-REINFORCED PROPYLENE COMPOSITION HAVING LOW EMISSIONS
Document Type and Number:
WIPO Patent Application WO/2018/182819
Kind Code:
A3
Abstract:
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 D3121-09 and a volatile organic content of about 100 micrograms per gram or less as determined by VDA 277.
