EFFECT OF BLEND COMPOSITION ON ABRASIVE WEAR OF RED MUD FILLED PP LDPE BLENDS/

Effect of blend composition on abrasive wear behaviour has been studie d for red mud (RM) particulate filled blends of isotactic polypropylen e (PP) and semicrystalline low density polyethylene (LDPE) by using tw o body abrasion tester. Wear rate has been correlated with the composi tion and structure of the studied systems. Wear rate decreased with th e increase of PP content in those blend compositions where PP form the matrix, whereas reverse was observed in case of compositions in which LDPE forms matrix. Mechanism of this behaviour has been explained on the basis of X-ray diffraction studies and interaction amongst the con stituents of composites.
