A corner trim material that is made of a material that will bond with current industry mastics such as all purpose joint compounds, resists impact, resists abrasion, and readily accepts common coatings such as drywall mud, texture and paints. The surface of this material generally does not need to be covered by any secondary fiber based material such as paper to improve bonding or coating on the inside or outside. The material generally consists of a polymer mixed with a fibrous material like pulp or glass fiber. A corner trim piece can be directly extruded from the mix. The corner trim piece can have a center hinge, can be bullnose, and the flanges can optionally have holes or optionally be coated with adhesive.

A method of sub-ambient pressure processing of blow-molded polymer foams and skin-over-foam sandwich panel configurations for lightweight components having improved structural properties. The method can create either skinned or un-skinned foams that offer smooth interior and exterior surfaces, zero or controlled surface porosity, skins of pre-defined thickness, and foam cells that are expanded and oriented normal to the material plane, effectively spherical or polyhedral in nature, and offering improved bending and compressive strength.

An apparatus for producing an object from a polymeric material having a melting temperature comprises: a melting device for melting the polymeric material, a heat exchanger for cooling the polymeric material melted by the melting device below the melting temperature, a mould arranged downstream of the heat exchanger for forming the object from the polymeric material, while the polymeric material has a temperature lower than said melting temperature, a heat recovery device associated with the heat exchanger, the heat recovery device being configured to recover at least part of the heat released by the polymeric material to the heat exchanger.

A method for forming an annealed thermoplastic tape is disclosed. The method includes supplying continuous fibers to an extrusion device, supplying a thermoplastic feedstock to the extrusion device, wherein the feedstock comprises a thermoplastic polymer, pre-heating, tensioning, spreading, and flattening the continuous fibers, extruding the continuous fibers and the feedstock within an impregnation die to form an extrudate in which the continuous fibers are embedded with a matrix of the thermoplastic polymer while under continuous tension and heat, and maintaining the continuous tension on the extrudate until cooled to a solid thermoplastic tape. The resulting annealed thermoplastic tape is formed of a plurality of unidirectional fibers, and a thermoplastic resin.

The invention relates to an extrusion blow-molded container, the inside of which is defined by a container side wall and a container bottom, a standing area being detachably connected to the container side wall and to the container bottom. According to the invention, at least a subarea of a bottom of a primary container product formed from the parison is irreversibly moved into the container such that an undercut container bottom is embodied on the container at least in a subarea, the standing area of the container being formed in the region of the undercut container bottom from a side wall of the primary container product by bending and/or pressing down.

A method for manufacturing a plastic fuel tank including: a) inserting a plastic parison including two distinct parts into an open two-cavity mold; b) inserting a core, bearing at least part of a reinforcing element configured to create a link between the two parison parts, inside the parison; c) pressing the parison firmly against the mold cavities, for example by blowing through the core and/or creating suction behind the cavities; d) fixing the part of the reinforcing element to at least one of the parison parts using the core; e) withdrawing the core; f) closing the mold, bringing its two cavities together to grip the two parison parts around their periphery to weld them together; g) injecting a pressurized fluid into the mold and/or creating a vacuum behind the mold cavities to press the parison firmly against the mold cavities; and h) opening the mold and extracting the tank.
