Thermal Stabilization of PVC Using Organic Modified Montmorillonite

Abstract:

There has been a number of works trying to improve thermal stability of PVC as it is one of the most widely used plastics for various applications. The incorporation of heat stabilizer is a general method to stabilize PVC. However, its thermal stability could also be improved by blending with polyethylene. Organoclay, montmorillonite (MMT) in particular, has been found to improve thermal stability of polymers due to its high temperature resistance. This research is aimed to use organic modified MMT (OMMT) to improve thermal property of PVC. It was found from the research that organic grafted MMT (O-g-MMT) could improve thermal stability of PVC better than OMMT. The mechanical properties of O-g-MMT/PVC and OMMT/PVC of the blends were also reported
