Pound/volume economics is a concept that takes advantage of differences between plasticizer efficiencies. For example, to produce a compound, based on one plasticizer, that has certain physical properties, it would require more or less of another plasticizer, depending on efficiencies. Specifically more Jayflex DINP or Jayflex DIDP is needed than lower molecular weight plasticizers. As a result, less PVC resin is required, reducing the ratio of PVC to plasticizer. This results in lower formulation costs on a volume basis.
Additional savings are possible in formulations made with lower density Jayflex plasticizers. This allows the formulator to add filler to equalize compound density.
* Savings on total formulation costs as a percentage of the cost of the plasticizer present in the formulation.
Computer Formulation and Costing To perform preliminary economic and performance evaluations of vinyl compounds, ExxonMobil Chemical developed two computer programs called JCOST and COPPCO.
