    IPC: C08J5/04

    Abstract: The invention relates to a process for producing a glass fiber-reinforced thermoplastic polymer composition, comprising the sequential steps of: a) unwinding from a first package of at least one first continuous glass multifilament strand having a first filament thickness t1 and a second package of at least one second continuous glass multifilament strand having a second filament thickness t2 larger than the first filament thickness t1 and b) applying a sheath of a thermoplastic polymer composition around the at least one first continuous glass multifilament strand and the at least one second continuous glass multifilament strand to form a sheathed continuous multifilament strand.

    IPC: C08L23/16

    Abstract: The present invention relates to a thermoplastic composition, e.g., for automotive parts, comprising: (A) from 10 to 69 wt. % polypropylene(s); (B) at least 30 wt. % heterophasic propylene copolymer comprising: from 70 to 92 wt. % a propylene-based matrix consisting of a polypropylene, wherein the propylene polymer has an intrinsic viscosity IVPP; from 8 to 30 wt. % dispersed ethylene-α-olefin copolymer having an ethylene content of between 10 and 55 wt and an intrinsic viscosity IVEPR; and wherein the ratio of IVEPR/IVPP is between 3 and 7; C) from 0-30 wt. % ethylene-α-olefin elastomer comprising ethylene and a C3 to C10 α-olefin; D) from 1 up to 30 wt. % talc as a filler; E) from 0-10 wt. % high-density polyethylene (HDPE); and F) from 0-3 wt. % additional additives.

    Abstract: The invention is directed to a polypropylene composition, to a three-dimensional article comprising said polypropylene composition, and to the use of said composition for automotive articles. The polypropylene composition of the invention comprises: —40-90% by total weight of the composition of a polymer blend comprising polypropylene having a melt flow index as measured according to ISO 1133 at 230° C. and 2.16 kg of 2.0-100 g/10 min; —5-25% by total weight of the composition of one or more plastomers; —0.5-25% by total weight of the composition of mineral filler selected from the group consisting of phyllosilicates, mica or wollastonite; and —0.2-4% by total weight of the composition of glass fibers having an average fiber diameter in the range of 5-30 μm.
