Thermal, spectroscopic and morpholo

Thermal, spectroscopic and morphological analysis for the
application to refrigerator plastics by mechanical recycling from
polypropylene in waste-appliances was performed. The results
shows that RPP has no impurities such as calcium carbonate and
talc (magnesium silicate), and is impact enhanced copolymer. Performance
evaluation tells that the RPP of extended closed-loop
recycling has relatively high Mw and balanced mechanical properties
with strength and toughness. RPP has good impact strength at
low temperature and is applicable to refrigerator plastics.
In view of economy, it is expected that RPP by the extended
closed-loop and mechanical recycling will have about 50% costmerit.
Furthermore, it is required to develop RPP by the open-loop
recycling for enlarging supply.
