The present invention provides a method for producing a biocompatible implant and a corresponding biocompatible implant. The biocompatible implant (10) has an implant body (8) composed of a polyaryletherketone plastic, wherein the implant body (8) has at least one first porous section (12) and one second porous section (13), wherein the first porous section (12) and the second porous section differ with respect to their porosity.

The disclosure relates to a mechanically recyclable label (1) comprising a face (2) and an adhesive (4). The face (2) comprises ethylene containing polymer and the adhesive (4) comprises pressure sensitive adhesive. The pressure sensitive adhesive comprises at least 15 wt. % of a base polymer, at least 25 wt. % of a tackifier and at least 10 wt. % of a plasticizer. The base polymer, the tackifier and the plasticizer are colourless and odourless. The base polymer is a styrene block copolymer. The mechanically recyclable label (1) is mechanically recyclable with packaging material comprising ethylene containing polymer. The disclosure further relates to a label laminate (8), a method for manufacturing a label laminate (8), a labelled item (101), as well as to use of a label (1) and of a label laminate (8). The disclosure also relates to use of a waste matrix of the label laminate for producing granulates of recycled plastic.

The embodiments relate to a polyester film, to a process for preparing the same, and to a process for regenerating a polyethylene terephthalate (PET) container using the same. The polyester film has excellent seaming characteristics and recyclability by virtue of controlled crystallinity, whereby clumping rarely occurs even if it is thermally treated for a long period of time in the regeneration process.
摘要:
In the production of thermoplastic granulate material, after mixing the starting materials, it is common in the state of the art for these materials to be kneaded and compressed in extruders, with subsequent granulation. According to the invention, no extruder is used, rather the starting materials for the thermoplastic granulate material are supplied directly to a double belt press after the mixing. Subsequently, the generated web-type to sheet-type body is processed into a granulate material by means of grinding, or is used as a web-type, sheet-type, strip-type or film-type intermediate product for the production of a further intermediate product or end products.
摘要:
A process for producing pellets or granules comprising fibres of a lignocellulousic material, for use as a feedstock in plastics manufacture, conveying in a dry or wet air stream and applying to the fibres a liquid formulation comprising one or more polymers, monomers, or oligomers, forming the fibres into a solid product, and breaking down the solid product to produce said pellets or granules. Typically the conduit conveys the fibres in a plant for manufacture of fibre board.

The invention provides a method of using fabric cutting scrap, which method comprises the steps of: (e) cutting the cutting scrap into flakes, (f) admixing the flakes to a polymer melt, (g) kneading the polymer melt with the flakes, so the flakes disintegrate into individual fibers, (h) molding the polymer melt with the admixed fibers into an intermediate article.
摘要:
The present invention relates to a roller cooling device for the continuous conversion of a hot flowable mass into solid chips by cooling, with at least one cooling roller, one crushing roller and one pressing belt, rotating via deflecting pulleys. The cooling roller and crushing roller serve for rolling out the mass into a thin film. The pressing belt runs on a part circumference of the cooling roller and serve for pressing the film against the cooling roller there. The parts are held from only one side and the rollers are mounted only on the same side and are driven from the same side, and in that said the parts are thereby accessible and/or demountable from the other side for cleaning purposes.
