  5. 5. PAGE<br />5 of 13<br />MAIN CONTROL<br />BACK<br />NEXT<br />EXIT<br />Mark FalcóBsc Chemistry<br />1. IntroductionMajorhindrances<br /><ul><li>Rubber crumb has a vulcanised thermosetting nature, hence is incompatible with HDPE.</li></ul>Modify chemically the surface of <br />crumbed rubber or HDPE.<br />Common Solution<br /><ul><li>Through compatibilisation, the rubber particles are easily dispersed in the glassy matrix and the mechanical properties improve.
  6. 6. Even though, compatibilisation represents a dramatic rise in cost. </li></ul>03.06.2010 London, UnitedKingdom<br />London MetropolitanPolymer Centre<br />

  8. 8. The mixture can be processed in conventional machinery.
  9. 9. Represents an alternative solution for waste rubber disposal.
  10. 10. Wide profit margin due to the low cost of waste rubber. </li></ul>03.06.2010 London, UnitedKingdom<br />London MetropolitanPolymer Centre<br />

  12. 12. Compare two different methods of processing this blend.
  13. 13. Achieve a the maximum optimal rubber particles dispersion throughout the matrix.
  14. 14. Scope the real possibilities of this composite. </li></ul>03.06.2010 London, UnitedKingdom<br />London MetropolitanPolymer Centre<br />

  20. 20. Devising a new method of mixing will be required, since the dispersion was weak.</li></ul>5. Futurework<br /><ul><li> Devise new mixing method.
  21. 21. Fracture analysis will be performed.
  22. 22. More Mechanical and characterisation tests will be carried out.</li></ul>03.06.2010 London, UnitedKingdom<br />London MetropolitanPolymer Centre<br />
