A method of preparing a film comprising contacting a recycled polypropylene with a cavitating agent and an optional virgin polypropylene to form a mixture; extruding the mixture to form an extrudate; and biaxially orientating the extrudate to form a biaxially oriented film.

An extruder configured to extrude a solid raw material containing moisture includes a barrel, a hopper coupled to one side of the barrel, a discharge port, a screw, vent disposed between the hopper and the discharge port to discharge vapor generated within the barrel; and a heater mounted on the barrel to heat the raw material. Raw material introduced into the barrel through the hopper is heated by the heater while being transferred within the barrel through the screw. A kneading zone, in which raw materials transferred by the screw threads are compressed, is formed on the screw. Since the raw material is melted within the barrel, a heating temperature of the heater and an axial rotation speed of the screw are controlled so that a sealing membrane that shields an inner transverse section of the barrel is formed from the liquid raw material in the kneading zone.

An extruded polymer composite may include a polymer matrix. An extruded polymer composite may include and a filler content greater than about 65 wt % homogenously distributed about the polymer matrix.

The present disclosure provides a composite material comprising a homogenous blend of (a) at least about 40% w/w of non-plastic organic matter out of a total weight of the composite material, said non-plastic organic matter comprising at least cellulose; (b) between about 5% w/w and about 60% w/w plastic matter out of a total weight of said composite material, said plastic matter comprising a plurality of synthetic thermoplastic polymers; and (c) up to 15% w/w inorganic matter; wherein said composite material comprises aryl containing synthetic polymers in an amount of less than 10% out of the total weight of said composite material; and wherein said composite material is characterized by at least one of the following properties: (i) it has a notched izod impact of at least 15 h/m; and (ii) a sample of said composite material that has been subjected to injection molding has at least one of tensile strength of at least 8 MPa; and flexural strength of at least 15 MPa. Also provided is a method of preparing the composite material, the method involving use of heterogenous intake material that comprises aryl-containing synthetic polymers in an amount of less than 10% out of the total weight of said composite material; and to methods of producing articles of manufacture from the composite material.

An extruder includes a mixing device having a mixing chamber formed by a housing, a stator and a rotor. The stator and the rotor are arranged at least partially within the mixing chamber. The stator is connected to the housing and/or is formed by the housing. The rotor is rotatable about an axis of rotation (D). At least one free space, into which the stator projects at least partially in the direction of the axis of rotation (D), is formed by the rotor. The stator and/or the rotor have/has at least one temperature control channel, through which a temperature control fluid can be made to flow in order to control the temperature of the stator and/or of the rotor. The extruder further includes a screw housing, a screw drive, and an extruder screw, which is mounted to the screw housing and is coupled to the screw drive.

Compositions include from about 50 wt % to about 85 wt % of a liquid crystal polymer resin, from about 0.1 wt % to about 15 wt % of a polyetherimide polymer, from about 0.05 wt % to about 8 wt % of a compatibilizer, and from about 2 wt % to about 25 wt % of a mineral filler. A 50 mm60 mm sample having a thickness of 0.6 mm molded from the composition exhibits an anti-dent performance characterized by a dent depth from 30-40 micrometers as measured using a three dimensional surface profiler; the sample is tested using a drop tester with a 1.6 mm diameter steel ball having a weight of 50 grams dropped from a height of 50 mm. Articles including the composition, including components of a mobile compact camera module, are also described.
