Polypropylene (PP) also known as polypropylene is a thermoplastic polymer used in wide variety of application. The main content of this paper are wear, polypropylene and its application. Wear by abrasion is form of wear caused by contact between a particle and solid material. Abrasive wear is the loss of material by the passage of hard particles over a surface. Abrasion in particular is rapid and severe forms of wear and can result in significant costs if not adequately controlled. These differences extend to the practical consideration of materials selection for wear resistance due to the different microscopic mechanisms of wear occurring in abrasion.This paper also emphasizes on different properties of polypropylene i.e. mechanical, thermal, chemical & optical properties. Wear tests are conducted using pin on disc multi orientation apparatus
