Auxetic polyurethane and melamine foams by triaxial compression
Described herein is a process for preparing a foam (FA) with a Poisson's ratio in the range of from −0.5 to 0.3, the method including the steps of providing a foam (F1) with a flow resistance in the range of from 3000 to 8000 Pas/m, determined according to DIN EN 29053, and subjecting the foam (F1) to thermoforming including triaxial compression, wherein the foam (F1) is not reticulated prior to step (ii). Also described herein is the foam obtained or obtainable according to the process and the use of the foam as, for example, an energy absorbing device, preferably in protective gear, furniture, cushions, in cleaning devices with improved rinse-out behavior, in shoe soles, or as sealing, insulating or anchorage providing material for example used in earphones, ear plugs or dowels, or as acoustic material.
Edge modification method and apparatus
An improved method of edge modification such as edge banding comprising placing a roller in contact with an edge and measuring a first position of the roller. Subsequently moving the contact roller along the edge to a second position and measuring the second position before calculating a desired force direction from the first and second position measurements, applying a force via the pressure roller in the desired force direction.
Self-adhesive patch
A self-adhesive patch formed of leather, bonded leather or synthetic leather for application to furniture, garments and luggage is provided with a debossed peripheral region which is coplanar with the reverse side of the patch and denser than the remainder of the patch. When applied, the edge of the patch is therefore lower than the main body of the patch and less likely to be unpeeled from the item to which it is attached.
Articles with one or more viewable objects therein
An article includes at least first and second members. A decorative object is within the second member. Interlocking features are adapted to removably interlock the first and second members together. The interlocking features include a channel and a rail that are complementarily shaped so that the rail is receivable within the channel to removably interlock the rail with the channel. At least the second member is formed of a translucent or transparent material so that the decorative object within the second member is visible through the member.
High flow rotomolding compositions, processes thereof, and articles therefrom
Compositions may include a polymer melt blend composition prepared from two polyethylene copolymers having different densities, wherein the polymer melt blend composition possesses improved flowability and impact resistance for low thickness rotomolding applications. Low thickness articles may include a polymer melt blend composition prepared from two polyethylene copolymers having different densities, wherein the articles possess improved finishing properties. Rotomolding processes may include melt blending from two polyethylene copolymers having different densities, pulverizing the melt blend, and rotational molding the composition thereof.
High strength blow-molded structure
A blow-molded plastic structure has a hollow interior portion formed during a blow-molding process, and includes first and second outer portions that are spaced apart from each other, with the hollow interior portion disposed there between. The structure includes a pattern of structural stiffening features that are integrally formed in the second outer portion. The pattern of structural stiffening features includes a plurality of tripodal depressions disposed in rows and columns and a plurality of convex regions disposed in rows and columns between the plurality of tripodal depressions. Each convex region has a maximum height between the first and second outer portions. Each of the tripodal depressions extends into the hollow interior portion, includes three indentations disposed adjacent the first outer portion, and includes an island spaced away from the first outer portion. The island has three sides, each of which is disposed adjacent one of the three indentations.
Method of manufacturing a stiff engineered composite
The method of making a compressed biocomposite body includes compressing a mass of biocomposite material comprised of discrete particles and a network of interconnected glucan-containing mycelia cells in the presence of heat and moisture into a compressed body having a density in excess of 18 pcf. Compression may take place batch wise in a press or continuously in a path of narrowing cross-section defined by a series of heated rollers.
Systems and methods of UV printing on substrates
A system and method for printing patterns on a substrate, including a substrate; a powder; a sealing coating; and a UV curable paint; wherein the powder, the sealing coating and the UV curable paint are deposited onto the substrate and heated and cured. The method is designed to make the substrate have a faux appearance with lower costs than manufacturing the real substrate it was meant to look like.
ARRANGEMENTS FOR PREPARING OF FURNITURE PRODUCT
In one aspect there is provided a tool arrangement for manufacture of a furniture product including a building element, such as a building panel. A tool configuration is configured to be displaced, such as linearly displaced, along a primary axis. The tool configuration includes a drilling device including a drill configured to form an insertion groove in a surface of the building element by means of axial displacement along a longitudinal centre axis of the drill in a direction towards the building element. The tool configuration further includes a dispenser device configured to dispense adhesive means into the insertion groove and an inserter device configured to arrange a locking means in the insertion groove. The longitudinal axis of the rotatable tool is preferably arranged at an acute angle to the primary axis and/or to the surface.
Process for producing longer fibers in injection molded solid parts by dissolving of gas during plasticizing
The disclosure is directed to a solid part, and a device and process of making the solid part. The process includes introducing a glass fiber filled polymeric material to a hopper of an injection molding machine, where the glass fibers have a pre-molding length, melting the glass fiber filled polymeric material to form a melt in a plasticizing unit, pressurizing the plasticizing unit of the injection molding machine with a blowing agent, dissolving the blowing agent into the melt, injecting the melt into a mold cavity up to 100% of volume, and forming the solid part.
