Reduce PVC Production Cost with Calcium Carbonate powder

The effects of virgin PVC percentage, recycled PVC percentage, CaCO3 percentage and particle size, and plasticizer percentage and type; on the mechanical properties of PVC electrical insulation and cost were examined. The DoE mixture approach was adopted in designing the experiments and analyzing the results.
The analysis showed that for maximum UTS the compound should consist of: 17.5% DOP, 62.5% virgin PVC, and 20.0% CaCO 3 of particle size 5 microns.
For the highest ductility the compound should be made of 35% virgin PVC, 20% CaCO 3 of particle size 5 microns, and 45.0% DOP plasticizer.
Finally, a minimum materials cost for a PVC insulation of an electrical cable can be achieved through using 20% virgin PVC, 18.75% recycled PVC, 43.75% CaCO 3 with participle size 10 microns, 14% DOP plasticizer, and 3.5% CPW plasticizer. This minimum-cost composition will result in ASTM acceptable values of 17.32 MPa for the UTS, 322% ductility, and it will cost 0.97 $/Kg under the Jordanian market conditions.
