Wear factor (K) is an indication of a materials resistance to wear as a function of the volume of material lost, force (load) and velocity at the wear interface and time. It is often determined using a "thrust washer" wear testing apparatus per ASTM D3702 in which a molded plastic specimen is rotated against a substrate thrust washer under set pressure and velocity conditions.

A wear factor is calculated with the equation W=K*F*V*T. In this equation W is wear volume (mm3), K is wear factor (mm3/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.

Comparing competitive data note

  • RTP Company reports Wear Factors per unit Force (KF) with units of (mm3/N m)10-8. This is the industry standard way to calculate and report Wear Factor. Some suppliers report Wear Factors per unit Pressure (KP) with units of (mm3/Pa m)10-11. This value is arrived at by dividing the KF by the contact surface of the test specimen 0.00023 or 2.3-4 m2. As result of this reporting discrepency, RTP Company's Wear Factor values appear to be significantly higher. For example a KP of 3 (mm3/Pa m)10-11 would be equal to KF of 3/0.00023 = 13 (mm3/N m)10-8.
