Composition polypropylene / talc with improved impact behavior
2010
Polypropylene composition comprising polypropylene (PP) and at least two substances of different mineral fillers (F1) and (F2), wherein (a) the first mineral filler (F1) has a median size d50 [mass percent] as determined by sedimentation technique, is at least 0.5 microns to less than the median size d50 [mass percent] as determined by sedimentation technique, the second mineral filler (F2), and (b) the second mineral filler (F2) has an index lamellarity (LI) higher than 2.90, lamellarity index being defined by the formula (I) wherein d50 (L) is the median size d50 [mass percent] as determined by laser diffraction technique, and d50 (S) is the median size d50 determined [weight percentage] by sedimentation technique.
