STUDY ON PHYSICO-MECHANICAL PROPERTIES OFRADIATION RESISTANT PVC-NBR COMPOSITES

Abstract

Gamma radiation is very important in polymer industry and in polymer applications. It is very harmful for human body to the protection of gamma rays a plasticized PVC sheet has been made which remains stable under the certain amount of gamma radiation dose . PVC can be converted easily into to a desired shape. Mechanical properties of PVC are very important for the application purpose . It’s properties can be changed easily by giving it the various type of radiation doses , radiation makes it more applicable in various uses. Different compositions were prepared and were exposed to different gamma radiation dose to study different mechanical properties .The plasticized PVC sheets were analyzed before and after radiation for various properties such as density ,tensile strength ,tear strength ,elongation and hardness etc.
