THE RHEOLOGICAL AND MECHANICAL PROPERTIES OF VIRGIN HDPE/CaCO_3 AND RECYCLED HDPE/CaCO_3 BLENDS

摘要

Mineral fillers such as CaCO_3 were used to improve the properties of products made from HDPE and recycled HDPE. This work reports that incorporation of CaCO_3 improved modulus and impact strength. The study also showed that the CaCO_3 facilitated processing of recycled HDPE by preventing segregation of polyolefin with different MFIs and improving melt homogeneity, mechanical properties and extrusion output.
