Claims15
A polypropylene composition comprising:
- A) from 31 wt % to 69 wt % of a recycled polypropylene composition having:
- i) ethylene derived units content, measured by 13C-NMR, ranging from 1.0 wt % to 4.2 wt %;
- ii) 1-butene derived units content, measured by 13C-NMR, ranging from 1.5 wt % to 5.2 wt %;
- iii) ethylene derived units content of the fraction soluble in xylene at 25° C., measured by 13C-NMR, ranging from 6.0 wt % to 15.0 wt %;
- iv) 1-butene derived units content, of the fraction soluble in xylene at 25° C., measured by 13C-NMR, ranging from 2.8 wt % to 8.2 wt %;
- v) Melt Flow Rate, determined according to the method ISO 1133 (230° C., 2.16 kg), ranging from 5.0 g/10 min to 20.0 g/10 min;
- vi) Xylene Soluble fraction at 25° C. ranging from 4.8 wt % to 10.7 wt %;
- vii) melting point measured by DSC according to ISO 11357-3, ranging from 135° C. to 149° C.;
- (B) from 31 wt % to 69 wt %;
- of a propylene ethylene copolymer having:
- i) ethylene derived units content, measured by 13C-NMR, ranging from 1.8 wt % to 6.1 wt %,
- ii) a Melt Flow Rate, determined according to the method ISO 1133 (230° C., 5.0 kg), ranging from 0.3 g/10 min to 2.8 g/10 min;
- iii) a Xylene Soluble fraction at 25° C., determined according to ISO 16152:2005, ranging from 4.5 wt % to 12.5 wt %;
- wherein the Melt Flow Rate of the polypropylene composition, determined according to ISO 1133 (230° C., 2.16 kg), ranges from 0.7 g/10 min to 6.0 g/10 min;
