A production method of producing a fiber-reinforced resin molding includes: kneading, in a kneader, molten thermoplastic resin with opened reinforcing fibers obtained by opening a bundle of reinforcing fibers, to produce a kneaded mixture; and placing or charging the kneaded mixture into a molding device to produce a fiber-reinforced resin molding.

A starter for the devulcanisation of scrap rubber. The abstract of the disclosure is submitted herewith as required by 37 C.F.R. §1.72(b). As stated in 37 C.F.R. §1.72(b): A brief abstract of the technical disclosure in the specification must commence on a separate sheet, preferably following the claims, under the heading “Abstract of the Disclosure.” The purpose of the abstract is to enable the Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract shall not be used for interpreting the scope of the claims. Therefore, any statements made relating to the abstract are not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner.

Apparatus and methods for manufacturing compostable, biodegradable drink straws from polyhydroxyalkanoate (PHA) material are disclosed herein. Such apparatus may include a hopper that contains raw PHA material, an extruder that receives the raw PHA material from the hopper and produces extruded PHA material, one or more waters baths that cool the extruded PHA material, a puller that pulls a tubular stream of PHA material through the system, and a cutter that is configured to cut the stream of PHA material into finished straws. The finished straws may be soil- and marine-biodegradable, as well as home- and industrial-compostable.

Disclosed herein is a multilayered article comprising a core layer comprising a thermoplastic polymer; where the thermoplastic polymer comprises a polyolefin, thermoplastic starch, and a compatibilizer; where the compatibilizer does not contain ethylene acrylic acid; where the polyolefin is not polypropylene and where the polyolefin present in an amount of greater than 40 wt %, based on a total weight of the core layer; a first layer comprising a thermoplastic resin; and a second layer comprising a thermoplastic resin; where the first layer and the second layer are devoid of fillers; where the first layer is disposed on a side of the core layer that is opposed to the side that contacts the second layer; where the multilayered article has an optical clarity of greater than 80% when measured as per ASTM D 1746 and a total haze less than 8% when measured as per ASTM D 1003.

A method of making a mesh cushion. The method includes extruding a material through a plurality of filament forming openings in at least one die plate to form a plurality of filaments. The filaments may be at least partially submerged into a fluid to cool and harden the filaments into the mesh cushion.

This invention provides a food container which can be manufactured cheaply by using inexpensive general PET resin or further inexpensive PET resin for fiber or recovered PET flakes, and nevertheless, which has a high heat resistance up to 250° C., and the container is obtained by adding a chain extender and a compatibilizer and talc to PET resin, charging the mixture into an extruder 30 having two or more vent holes, degassing under a condition where the PET resin is melted with heating by sucking at a high vacuum of −99.99 kPa or lower from the vent holes 33, 34, thereafter, forming a sheet by extrusion molding, pressure-forming with vacuum the sheet by a thermoforming machine, forming the container by keeping in a mold at 100-220° C. The container has a total of the content of crystal portion represented by the following formula and the content of talc being 25% by weight or more.

A method utilizes waste product in manufacturing, such as manufacture of filaments or micro-pellets for use in manufacturing applications such as additive manufacturing, extrusion, injection molding, blow molding and other applications.

An extruder and molding assembly comprising an extruder positioned upstream from a mold, the mold having a mold cavity and a separate pressurization member fluidly connected to the mold cavity wherein the extruder is operable at a first pressure to fill at least a majority of the mold cavity and the pressurization member is operable to fill a remainder of the mold cavity.

The invention relates to a process for the production of articles, exemplarily a plastic article, by means of an extruder (1) to which a first plastic composition of a first main component and at least one associated minor component is supplied from a first group of dosing stations (21, 24). According to the invention, during the production time of a first production order there is prepared a second group of dosing stations (31, 33) at the extruder for a second production order for which a second plastic composition of a second main component and at least one associated minor component that is different from the first plastic composition has to be supplied to the extruder. After completion of the first production order it is reset to the second production order by terminating the supply of the first plastic composition by closing a first shut-off device (8) and starting the supply of the second plastic composition by opening a second shut-off device (8′).

The present disclosure relates generally to polyurethane matrix composite materials, for example, suitable for making an exterior cladding product for houses and other buildings. The present disclosure relates more particularly to a polymer matrix composite material including a polyurethane matrix and an inorganic filler in a range from 45% to 85% by weight of the composite material. The inorganic filler includes a first substance from the group consisting of calcium carbonate, sand, talc, kaolin clay, dolomite, feldspar and mica and any mixture thereof, and fly ash, and/or an iron oxide in a range from 0.5% to 7% by weight of the inorganic filler.
