POLYOLEFIN MASTERBATCH AND COMPOSITION SUITABLE FOR INJECTION MOLDING
摘要
A masterbatch composition comprising: 70-90 %wt of a component (A) being a propylene homopolymer or copolymer of propylene with ethylene or C4-C10 alpha olefins, having a MFRA according to ISO 1133 (230°C/2.16 Kg) ranging from 15 to 70 g/10 min; and 10-30 %wt of a component B) being a propylene-ethylene copolymer comprising 25-45 %wt of ethylene derived units and having a value of the intrinsic viscosity [?] of the fraction soluble in xylene at room temperature ranging from 5 to 9 dl/g, said masterbatch composition having a total MFR higher than 4 g/10 min, and a value of the fiexural modulus measured according to ISO method 178 ranging from 950 to 2000 MPa.
