<p>A composition comprising a fluoroelastomer o-ring containing fibers which serve as a filler, said fibers having an L/D ratio of at least 15 and being oriented so that at least 25% of the fibers are at an angle of 30 DEG or less from radii through the center and in the plane of the o-ring. Thus the fibers are primarily radially oriented. The o-ring has improved compression set.</p> |
