TPEGTR blends based on EPR show a smaller viscosity, close to
the pure highly flowable PP, even for the P30(V0.7G0.3)70 blend with
21 wt % GTR. This rheological behaviour shows that formulation of
TPEGTR blends for the injection moulding industry is a feasible
strategy for GTR recycling, which can broaden the application for
this type of potentially wasted material in new and interesting
areas.
