A multicolor wood-plastic profile is made of a color master batch and a wood-plastic base material. The ratio λ of the tensile elastic modulus (Et) of said color master batch to that of said base material is 0.26-1.47. A manufacturing method for the multicolor wood-plastic profile includes mixing and melt extruding the color master batch and the base material. A wood-plastic board, including the multicolor wood-plastic profile. The outer surface and the interior of the multicolor wood-plastic profile have two or more colors, presenting a mixed gradual texture similar to natural wood.

An extruding unit, a forming roll unit and a thick portion forming mechanism are provided. The extruding unit has an ejecting slit which ejects sheet-shaped molten resin. The ejecting slit includes a standard gap portion and an enlarged gap portion. The standard gap portion is formed as a gap having a constant size. The enlarged gap portion is formed as a gap larger than the standard gap portion in a position corresponding to a thick portion. The thick portion forming mechanism forms one or several thick portions which are thicker than other portion, in the sheet-shaped molten resin continuously in the extrusion direction.

The present invention discloses a composition that may be extruded or injection moulded, comprising a chemically modified hardwood lignin and a polyester. The chemically modified hardwood lignin constitutes 10 to 50 weight-% of the total weight of the composition.

Techniques for forming a helical rubber hose are provided. Such techniques include modified crosshead extrusion techniques in which an elastomer is melted, fed into a crosshead assembly, and extruded on a helical mandrel fed through the crosshead assembly to form a hose. In techniques described herein, relative axial and rotational motion of the mandrel and a die plate at or on the outlet or output of the crosshead assembly are kinematically matched such that the distance of relative axial movement of the mandrel per one revolution equals one pitch of the mandrel.

Methods making a metal-organic framework extrudate in an extruder comprising the steps of: (a) mixing a metal-organic framework material with an extrusion aid to form a metal-organic framework extrudate mixture; and (b) extruding the metal-organic framework mixture in the extruder to produce the metal-organic framework extrudate where the pressure within the extruder is reduced between about 10% to about 55% when compared to pressure within the extruder when extruding the metal-organic framework material without the extrusion aid. The extrusion aid can be a liquid extrusion aid, a solid extrusion aid and/or a polymeric extrusion aid.

An optically anisotropic polymer thin film includes a crystallizable polymer and an additive configured to interact with the polymer (e.g., via π-π interactions) to facilitate chain alignment and, in some examples, create a higher crystalline content within the polymer thin film. The polymer thin film may be characterized by a bimodal molecular weight distribution where the molecular weight of the additive may be less than approximately 50% of the molecular weight of the crystallizable polymer. Example crystallizable polymers include polyethylene naphthalate, polyethylene terephthalate, polybutylene naphthalate, polybutylene terephthalate, as well as derivatives thereof. Example additives, which may occupy up to approximately 10 wt. % of the polymer thin film, include aromatic ester oligomers, aromatic amide oligomers, and polycyclic aromatic hydrocarbons, for example. The optically anisotropic polymer thin film may be characterized by a refractive index greater than approximately 1.7 and an in-plane birefringence greater than approximately 0.2.

In this specification, a method for the manufacture of solid dosage forms is disclosed. The method includes extruding a plasticized matrix through an exit port of an extrusion channel to form one or more plasticized fibers, structuring said fibers to a three dimensional structural network by patterning on a translating or rotating stage, and solidifying the patterned structure.
