On the possibility of replacement of calcium carbonate by a high-performance, economically viable filler in polyethylene composites
Abstract
<jats:p> Calcium carbonate (CaCO<jats:sub>3</jats:sub>) is frequently added to polyethylene (PE) as a filler to reduce costs. An alternative to CaCO<jats:sub>3</jats:sub>, calcium fluoride (CaF<jats:sub>2</jats:sub>) was proposed in this research. PE/CaCO<jats:sub>3</jats:sub> and PE/CaF<jats:sub>2</jats:sub> composites in a wide composition range (0–60 wt.%) were prepared through a parallel twin screw extruder. Results indicated better interaction of CaF<jats:sub>2</jats:sub> with PE matrix which improved samples yield stress. Statistical analysis showed the filler type was more influential factor on the yield stress while filler loading was not a statistically significant one. In contrast, crystallinity was strongly depended on the filler loading. The dynamic mechanical and rheological investigations revealed that PE/CaF<jats:sub>2</jats:sub> composites had higher stiffness at ambient temperature and possessed lower viscosity below 40 wt.% of filler loading compared to PE/CaCO<jats:sub>3</jats:sub> which could reduce the processing cost. Therefore, regarding its low price and good functional properties, CaF<jats:sub>2</jats:sub> can be a promising alternative to CaCO<jats:sub>3</jats:sub>. </jats:p>
