USE OF A POLYPROPYLENE BASED COMPOSITION FOR EXPANDED BEADS

摘要

Use of a polypropylene based composition (C) comprising (a) from 5 to 95 % by weight of a random copolymer of propylene (A) containing from 0.5 to 12 mole% of at least one comonomer chosen from ethylene and/or an alpha-olefin containing from 4 to 6 carbon atoms, and having an MFI(A) in the range from 0.01 to 5 g/10 min,(b) from 95 to 5 % by weight of a random copolymer of propylene (B) containing from 0.5 to 12 mole% of at least one comonomer chosen from ethylene and/or an alpha-olefin containing from 4 to 6 carbon atoms, and having an MFI(B) in the range from 15 to 1000 g/10 min,said composition (C) being such that random copolymers (A) and (B) contain the same comonomer(s) and have, for each comonomer, substantially the same comonomer content,for the manufacturing of expanded beads.
