POLYOLEFINISCHE ZUSAMMENSETZUNGEN MIT HOHER BLEICHUNGSRESISTENZ |
摘要 |
A polypropylene composition comprising 65-77 wt % of a crystalline propylene polymer, 8 to less than 13 wt % of an elastomeric copolymer and 10-23 wt % of polyethylene. The said composition exhibits a flexural modulus value higher than 1300 MPa, stress-whitening resistance values corresponding to a diameter of the whitened area of at most 1.7 cm caused by a ram falling from a 76 cm height and a diameter of the whitened area of at most 1.2 cm caused by a ram falling from a 20 cm height, and a value of Izod impact resistance at 23° C. more than 14 kJ/m2 and the one at −20° C. at least 5 kJ/m2. |
