Penelitian pemanfaatan Minarex-B yang merupakan hasil samping pengilangan minyak sebagai bahan pemlastis sekunder dalam pembuatan kulit imitasi PVC

Application research of Minarex B type 2 and 3 as secondary plasticizer material in making PVC imitation leather is carried out through some stages, i.e. : 1. Making imitation leather sheet, 2. Physical testing of PVC imitation leather sheet, 3. Data analyzing from physical testing result. In making PVC compound for imitation leather lining is used to kinds of formulation, i.e : formula I (standard, without Minarex B), and formula II (with Minarex B). PVC imitation leather in this research consists of plastic lining and fabric lining, plastic lining consist of three linings, i.e : top coat, middle coat and base coat. Total Minarex B applicated is varieted, i.e : 4 part, 5 part and 6 part from subtitution result total DOP in PVC compound formulation. Physical testing data is evaluated to determine total and type of optimal Minarex B, so that it can be taken the conclusion that Minarex B can be used/applicated as secondary plasticize material in making PVC imitation leather with optimum limit 4 part. Optimum result Minarex B type 2 is not significance different from type 3.
