Interaction of mixing factors with mechanical properties of PP/ENR blend via response surface methodology / Noraiham Mohamad … [et al.]

This research is carried out to establish interaction between mixing parameters with mechanical properties of polypropylene (PP) incorporated with epoxidized natural rubber (ENR). The blends of PP/ENR were prepared by melt compounding using an internal mixer and vulcanized through sulfur curing syst...
