w--mass fraction of another polymer in polymer blend (PE-LD,
PE-HD).
PE-HD (DuPont, [d.sub.3,50]=24-36 [micro]m) and PP (DuPont, [d.sub.3,50]=30-45 [micro]m) were provided as powders in spherical geometry.
Isotactic PP homopolymer (HD601CF) and
PE-HD (CG9620) for the model mixtures were provided by Borealis Polyolefines.
Recycled rigid packaging made up 15per cent of the market, where plastics were recycled into items such as drums and buckets made from recycled
PE-HD and PP as well as rPET for thermoformed sheet applications.
Two polymer matrices were employed in this work, PP homopolymer HF700SA and
PE-HD CG8410.
