Abstract
The aim of this work is to study the valorisation of two regenerated low density polyethylene (LDPE) coming from dirty wastes
by blending with polypropylene (PP) in presence of compatibilizer. The first step was the determination of the physico-chemical
properties of the two regenerated samples (density, melt flow index, water absorption, melting temperature and oxidation index)
and the mechanical properties (tensile and shore D hardness).
The second step was the characterization of the physical (density, water absorption) and mechanical properties (tensile and shore
D hardness) of LDPE / PP blends. In the third and last step, the effect of compatibilizer on the properties of LDPE / PP blends in
the same proportion was considered. Physical characterization (density, water absorption and morphology analysis by scanning
electron microscopy) and mechanical properties were carried out.
The results showed that this kind of blending has contributed considerably in performing properties of regenerated LDPE.
