POLYPROPYLENE COMPOSITE |
| 摘要 |
Fiber reinforced composition comprising (a) a polypropylene random copolymer comprising ethylene and/or C4 to C8 α-olefin (PP-RACO), (b) fibers (F), and (c) a polar modified polypropylene as adhesion promoter (AP), wherein (i) the polypropylene random copolymer comprising ethylene and/or C4 to C8 α-olefin (PP-RACO) heaving a melt flow rate MFR2 (230° C.) measured according to ISO 1133 of at least 5 g/10 min, (ii) the fibers (F) are selected from the group consisting of glass fibers, metal fibers, ceramic fibers and graphite fibers, and (iii) the polymer contained in the reinforced composition forms a continuous phase being the matrix of the fiber reinforced composition. |

1. Fiber reinforced composition consisting of:
(a) a polypropylene random copolymer comprising ethylene and/or C4 to C8 α-olefin (PP-RACO), (b) fibers (F), and (c) a polar modified polypropylene as adhesion promoter (AP), (d) optionally a masterbatch, and (e) optionally one or more additives, wherein:
(i) the polypropylene random copolymer comprising ethylene and/or C4 to C8 α-olefin (PP-RACO) heaving a melt flow rate MFR2 (230° C.) measured according to ISO 1133 of at least 5 g/10 min,(ii) the fibers (F) are selected from the group consisting of glass fibers, metal fibers, ceramic fibers and graphite fibers, and(iii) the complete polymer contained in the reinforced composition forms a continuous phase being the matrix of the fiber reinforced composition. |
