Analysis of abrasive wear behaviour of RM filled LLDPE

Effect of addition of red mud (RM) particles on abrasive wear resistance of linear low density polyethylene (LLDPE) has been investigated using differ ent wt% of RM particles incorporated in LLDPE and conducting two body abras ion tests on these samples. Worn surfaces are observed by using scanning el ectron microscope. Two stage wear loss behaviour has been observed for the RM filled LLDPE materials and found to be unique and different from the lin early increasing trend observed in case of unfilled LLDPE. Initially, wear loss is higher in filled LLDPE as compared to unfilled LLDPE. In the second stage after 20 m sliding distance, RM filled LLDPE shows increased wear re sistance and wear loss becomes constant due to presence of a large number o f fractured RM particles in the filled samples.
