Paper Title
PP Reinforced With Recycled and Treated Rubber Particles

Recycled rubber particles are blended with PP to produce a composite. The effect of addition of different recycled rubber particles weight percentage (0, 5, 10, 20, 30, 40, 50) was studied to assess mechanical properties of the composites. Recycled rubber particles were treated with H2SO4 to increase the mechanical adhesion between recycled rubber particles and polymer. The effect of treatment was studied and compared to the untreated composites. The used mechanical tests were bending and impact test and the toughness and modulus of elasticity were calculated. The results obtained from the tests were justified by scanning electron microscopy (SEM). The bending strength and the modulus of elasticity decrease with the increase of rubber wt % while the impact strength improves.
