摘要： A polypropylene composition comprising oligomers having a semi-volatile organic condensable (FOG, VDA 278 October 2011), content of 50 μg/g to about 400 μg/g of the total polypropylene composition, and volatile organic compounds (VOC, VDA 278 October 2011) in an amount of less than 80 μg/g of the total polypropylene composition, wherein the weight ratio of said oligomers versus said volatiles is more than about 5.0, wherein the polypropylene composition has an MFR2 (ISO 1133, 230° C., 2.16 kg) of 10 g/10 min or higher, wherein the polypropylene composition a flexural modulus (ISO 178 on injection moulded specimens of 80×10×4 mm prepared in accordance with ISO 294-1:1996) of from 1000 to 2000 MPa, and wherein the total quantity of slip agent is at least 500 ppm.
