The present invention relates to a biodegradable PLA filament composition for molding a porous structure. The biodegradable PLA filament composition for molding a porous structure according to one embodiment of the present invention includes polylactic acid (PLA) in 50% by weight to 60% by weight; polybutylene succinate (PBS) in 20% by weight to 30% by weight; polybutylene adipate terephthalate (PBAT) in 7% by weight to 9% by weight; an additive in 0.1% by weight to 1% by weight; a crystallization nucleating agent in 0.1% by weight to 1% by weight; a natural grapefruit seed powder (Jamongci_genu pectin type) in 0.1% by weight to 2% by weight; an inorganic filler in 1% by weight to 10% by weight; and a crosslinking agent in 0.001% by weight to 10% by weight.

Compositions of high molecular weight poly(hydroxy acid) polymer having good thermal stability and a weight average molecular weight of >100,000 by GPC. The compositions include one or more chain-terminator compounds/impurities which may be incorporated into the polymer and rendered harmless by the presence of appropriate amounts of bi-functional and multi-functional polymerization initiators. A process including first mixing glycolic acid and/or lactic acid (with chain-terminators), and a diol or di-acid initiator, and at least one multifunctional initiator to form a liquid monomer mixture in an agitated polycondensation reactor. Next, polycondensing to form a liquid reaction mixture comprising a pre-polymer having a weight average molecular weight of >10,000 by GPC, and greater than 80% by mole hydroxyl or carboxyl end-group termination, then crystallizing to form a first solid reaction mixture. Then, solid state polycondensing the solid reaction mixture to form a solid reaction mixture having a moisture level less than 50 ppm by weight. Then, mixing the solid reaction mixture with an appropriate reactive coupling agent in a melting and mixing extruder to couple and form the reaction mixture and form the final poly(hydroxy acid) polymer.

A 3D drawing arrangement includes a feeding passage, a heater, a filament moving system, and a controller which includes a control circuit and a finger detector electrically connected to the control circuit, wherein when the finger detector detects a presence of a finger of a user which is aligned with the finger detector, the control circuit starts operation of the filament moving system to feed a filament to the heater along the feeding passage, so that the filament is heated and melted by the heater to produce the melted material flow.

A method for producing an injection-molded product is provided, where sunflower hulls are processed into sunflower hull fibers at a maximum temperature T.sub.PFmax of less than 200° C. Then an injection-moldable composite material is produced by mixing the sunflower hull fibers with a plastic material at a maximum temperature T.sub.PCmax ofless than 200° C. Next the produced injection-moldable composite material is automatically injection-molded into an injection-molding tool such that a molded composite material is produced. The composite material introduced into the injection-molding tool has a temperature T.sub.IM of more than 200° C. in at least one section of the injection-molding tool. Then the molded composite material is removed such that the injection-molded product is produced. A corresponding injection-molded product and the use of especially prepared sunflower hull fibers as an additive are also provided.

Methods are disclosed including thermally processing a scaffold to increase the radial strength of the scaffold when the scaffold is deployed from a crimped state to a deployed state such as a nominal deployment diameter. The thermal processing may further maintain or increase the expansion capability of the scaffold when expanded beyond the nominal diameter.

Described are methods for manufacturing a plastic component, in particular a cushioning element for sports apparel, a plastic component manufactured with such methods, for example a sole or a part of a sole for a shoe, and a shoe with such a sole. The method for the manufacture of a plastic component includes loading a mold with a first material includes particles of an expanded material and fusing the surfaces of the particles by supplying energy. The energy is supplied in the form of at least one electromagnetic field.

A cartridge for a dispensing device contains at least one elongate film pouch, which is inherently non-rigid and which has a chamber for receiving a composition. The cartridge also contains a head part for interacting with the film pouch. The film pouch has an opening on a side facing the head part, which is closed by a cover. The cover has a predetermined breaking region. A method can be used for producing such a cartridge.
