摘要:
Polypropylene composition comprising (A) 60 to 95 wt% of a heterophasic polypropylene (HECO) comprising 10 to 30 wt% of dispersed phase with the dispersed phase having a comonomer content of 30 to 45 wt% and the HECO having a melt flow rate MFR PP in the range of 12 to 200 g/10 min and being prepared in the presence of a Ziegler Natta catalyst (ZN-C), (B) 0 to 15 wt% of one or more elastomers, (C) 5 to 20 wt% of at least one filler wherein the polypropylene composition fulfils inequation (1) fogging ≤ 0.02 MFR Comp + 0.3. The composition allows for a well-balanced combination of a good impact/stiffness balance, a good scratch resistance, low VOC and FOG emissions and remarkable good fogging values.
摘要:
The present invention relates to a heterophasic polypropylene resin comprising a crystalline propylene homopolymer matrix (A) and an amorphous propylene copolymer phase (B) dispersed within the matrix having excellent mechanical properties, in particular at low temperatures, and at the same time high flowability. Further, the invention relates to a production process of the heterophasic polypropylene resin, the use of such a resin in a polypropylene composition and to articles made of the heterophasic polypropylene resin.
摘要:
The present invention is directed to the use of a polypropylene composition comprising at least one heterophasic polypropylene and a filler for the production of at least partially painted articles which show both a good paintability and a good surface appearance; and the painted articles produced therefrom. Further the invention is directed to a polypropylene composition showing improved surface appearance and paintability.
摘要:
The present invention relates to a heterophasic polypropylene composition with rather high melt flow rate, high stiffness, good impact properties and an advantageous balance between stiffness and impact behaviour, as well as articles made thereof.
