Enhanced elastomeric stator insert via reinforcing agent distribution and orientation

A method of making a stator insert, comprising:

• incorporating a plurality of magnetic particles into a polymer, resulting in a mixture;
• forming a stator insert from the mixture wherein the plurality of magnetic particles have high aspect ratios;
• and
• applying a magnetic field to the stator insert, wherein the stator insert lies along a central axis and wherein said applying the magnetic field to the stator insert orients the plurality of high aspect ratio magnetic particles to be perpendicular to the central axis.

A stator insert comprising:

• an elastomeric component;
• a reinforcing agent;
• and
• silicon dioxide;
• wherein said silicon dioxide has a specific surface area of 5 m2/g to 50 m2/g, wherein a ratio of said reinforcing agent to said silicon dioxide is from 10:90 wt % to 70:30 wt %, and wherein the reinforcing agent and silicon dioxide are homogenously distributed throughout the elastomeric component.
