High wear factor
WebRubber abrasion resistance is the ability of the rubber to withstand such abrasive wear. Some forms of tough rubber excel in providing protection against abrasions, making them perfect for certain projects. Generally, abrasion is far more likely to occur when motion is involved, as this creates a greater rate of friction-induced wear.

WebApr 16, 2024 · The wear rate of the polymer was calculated as the wear volume loss per million cycles. The wear factor was determined using the formula k=\Delta V/ (F\cdot L) per ASTM G99-05, where \Delta V is the volume loss converted from mass loss and density, F is the compressive load, and L is the sliding distance. WebJan 1, 2016 · At one end, higher stress (e.g., for those knees with modest contact area) can produce fatigue-type highly accelerated wear that must be avoided in design. At this extreme, when the stress is very high, the wear factor of UHMWPE is bound to rise (which means the wear rate rises faster than just with rising load).
WebWear Factor and Coefficient of Friction Data. To capitalize on the benefits of thermoplastic compounds, it is helpful to understand the basics of wear and friction. Most engineers … WebOut of seven commonly recognized wear mechanisms (abrasion, adhesion, fatigue, corrosion, cavitation, erosion and fretting) the first four are most often the cause of extremely high or abnormal wear rates. It is remarkable how many decades (powers of ten) are shown on the normalized wear chart.
