Do the particle size, molecular weight, and processing of UHMWPE affect its thermomechanical and tribological performance?

UHMWPE has exhibited excellent performance when used as contact surfaces in tribological contacts. Traditionally, only grades, with narrow particle size and molecular weight distribution, have been deemed suitable for such applications. Now, various grades are available that different from each other based on their distribution. The question of whether the affects its properties presents a research gap. present study attempts to address this question. Additionally, effect processing is studied. It observed although minor differences were UHMWPE, they inadequate conclusively determine material.
