Claims13
A low warp, filled oxymethylene polymer composition comprising a normally solid oxymethylene polymer in an amount of from about 40 to 99 wt. % of the total composition and glass beads in an amount of from about 1 to 60 wt % of the total composition, said glass beads being present as a bimodal distribution of said glass beads comprising relatively large glass beads having a mean diameter of from about 65 to about 2,800 microns and relatively small glass beads having a mean diameter of from about 5 to about 200 microns, the ratio of mean diameters of said relatively large glass beads to said relatively small glass beads being about 6:1 to bout 550:1, the weight ratio of said relatively large glass beads to said relatively small glass beads comprising 2:1 to about 15:1.
