The force required to pull apart 1 square inch of plastic may range from 1,000 to 50,000 lbs. or higher. Steel and other structural alloys have much higher tensile strengths, such as SS304 at 84 kpsi.

"WebA wear factor is calculated with the equation W=K*F*V*T. In this equation W is wear volume (mm 3), K is wear factor (mm 3 /N m)10-8, F is force (N), V is velocity (m/sec), and T is elapsed time (sec). A material with a lower wear factor (K) has greater resistance to wear and these values are useful for material comparison purposes. " - High wear factor
