Development of isotactic polypropylene and stearic acid

Abstract Isotactic polypropylene (PP) composite films were developed with incorporation of CaCO 3 particles as active filler Stearic acid was used for the surface treatment of CaCO 3 to provide composite films having improved mechan-ical thermal and barrier properties against oxygen as well as water vapor in comparison to neat PP films

Curing behaviors mechanical properties dynamic

AbstractGround tire rubber (GTR) with crosslinked structure shows hardly any plasticity and processability giving rise to its relatively poor properties The thermal-mechanical shearing devulcanization can effectively break the three-dimension crosslinked network structure and restore a certain extent of plasticity and processability In this work reclaimed rubber (RR) was obtained by
