A composition including: (a) 30% to 99.8% by weight by weight of recycled material from a used single-layer and/or multilayer tube and/or tank having initially transported or contained motor vehicle fluids, the tube and/or the tank having a composition which predominantly includes at least one polyamide, the used tube and/or the used tank having been ground into granules and the fluid residues present in the tube and/or tank having been totally or partially extracted, (b) up to 70% of a semicrystalline aliphatic polyamide, (c) up to 0.2% of an additive, the polyamide of the used tube and/or the used tank having functions resulting from oxidation reactions chosen from the primary amide functions, nitriles, terminal methyl groups, alkenes, formamides, imides, carboxylic acids and alcohols and mixtures thereof, in a mole ratio greater than that of the same polyamide constituting a non-used tube and/or tank which has not yet transported or contained motor vehicle fluids.

A method of manufacturing bulked continuous carpet filament which, in various embodiments, comprises: (A) grinding recycled PET bottles into a group of flakes; (B) washing the flakes; (C) identifying and removing impurities, including impure flakes, from the group of flakes; (D) passing the group of flakes through an MRS extruder while maintaining the pressure within the MRS portion of the MRS extruder below about 1.5 millibars; (E) passing the resulting polymer melt through at least one filter having a micron rating of less than about 50 microns; and (F) forming the recycled polymer into bulked continuous carpet filament that consists essentially of recycled PET.

A method for manufacturing pellets from polymer, comprising: (1) melting polymer flakes in a first section of a melt processing unit to create a first single stream of polymer melt; (2) separating the first single stream of polymer melt into multiple streams of polymer melt by means of a separation element; (3) passing the multiple streams through a multiple stream section of said melt processing unit and exposing the multiple streams to a pressure within the multiple stream section of the melt processing unit as the multiple streams pass through the multiple stream section; (4) recombining the multiple streams into at least one combined stream of polymer melt; and (5) cooling the polymer melt and forming said pellets from the at least one combined stream. The intrinsic viscosity of the at least one combined stream may be determined and, in response, the chamber pressure within the multiple stream section adjusted.

The invention relates to a contact-adhesive tape which can be removed damage-free and residue-free by stretching the tape substantially within the adhesion plane and which consists of one or more adhesive substance layers, all made of a contact-adhesive substance expanded with micro-balloons, and one or two optional intermediate backings. The disclosed contact-adhesive tape consists exclusively of the aforementioned adhesive substance layers and optional intermediate backings, and the one external upper surface as well as the one external lower surface of the contact-adhesive tape are formed by said adhesive substance layer or layers.

The present invention relates to a graft copolymer and a method for preparing the same, wherein the graft copolymer has merits of a superior storage convenience compared to existing dry powder and a high whiteness index, and thus may be widely applied to various fields.

In a device for producing and filling container products, at least one hose (19) of plasticized plastic material can be extruded into an opened mold (7), starting from an extrusion head (13) along a hose guide. By at least one filling mandrel (1), which at least in one functional position extends through the extrusion head (13), a filling material can be introduced into the relevant container. At least one process gas feeder device (21, 23) can be used to bring a process gas into the interior of the hose (19). The process gas feeder device (21, 23) has a guide duct (21) extending inside the extrusion head (13) along the outside of the filling mandrel (1). At least part of the process gas introduced is discharged through the extrusion head (13) along at least one predeterminable exhaust gas duct (35), which is separated from the relevant guide duct (21).
