Pemanfaatan minarex sebagai secondary plasticizer untuk pembuatan kompon sepatu boot PVC

The purpose of the research is to find out optimum amount of minarex (side product from Pertamina Jakarta) as secondary plasticizer which can be added to PVS compound in order to obtain boots compound conforming to SII 1990-86: Sepatu boot PVC. Research yield is a slab made by hydraulic press machine. 1700 C and pressure 150 kg/cm2 and the time must be suitable with the thickness. From various types of minarex used for the research, four of them can be applied as secondary plasticizer at PVC compound for boots which conforms to SII 1909-89, i.e. minarex C type 2, minarex C type 3, minarex D type 3 for five parts each.
