摘要:
Flexible highly filled polyolefin compositions with improved balance of properties particularly for applications where softness and ductility at low temperature is requested comprising a soft heterophasic polyolefin composition the fraction soluble in xylene at 25°C of said polyolefin composition having IVgpc lower than 2.5 dl/g. Mw/Mn (GPC) equal to or higher than 4. Mz/Mw (GPC) equal to or higher than 2.5. Said polyolefin composition further comprising an inorganic filler (II) selected from flame-retardant inorganic fillers and inorganic oxides or salts and a further elastomeric polymer or polymer composition component (c) having flexural modulus (ISO 178) lower than 60 MPa, Shore A (ISO 868) lower than 90 and Tg (DMTA) lower than - 20°C.
