Abstract: The present invention relates to a reaction mixture for manufacturing an inorganic-filler based closed-cell rigid polyurethane or polyisocyanurate (PU or PIR) containing foam having a calorific value below 6 MJ/kg, preferably below 4.5 MJ/kg, more preferably below 3 MJ/kg, measured according to EN ISO 1716, the reaction mixture comprising: At least one polyisocyanate-containing compound; At least one isocyanate-reactive compound; An inorganic filler composition; At least one physical blowing agent; characterised in that said inorganic filler composition has bulk density higher than 2 g/cm3, preferably higher than 2.1 g/cm3, more preferably higher than 2.2 g/cm3, even more preferably higher than 2.4 g/cm3.

Abstract: A reactive mixture and method for making a thermoplastic polyurethane (TPU) flexible foam having a predominantly open-cell structure (open-cell content of ?50% by volume calculated on the total volume of the foam and measured according to ASTM D6226-10) and an apparent density below 200 kg/m3.

Abstract: A molded flexible polyurethane foam having a hardness gradient going from soft to hard from the top to the bottom of the foam. The hardness gradient in the foam is a result of a foam elasticity gradient which arises from a polymer elasticity gradient and/or density gradient. A method for producing a flexible foam having a hardness gradient and a reactive mixture suitable for making said flexible foam is disclosed. Furthermore, the use of the flexible foams having a hardness gradient in matrasses, cushions for seating (more in particular for use in automotive seating), furniture, automotive under-carpets and dash insulators is disclosed.

Abstract: Method of designing and manufacturing a distributor bar for use in a production line comprising a mixing head for providing a viscous foamable liquid mixture, a laminator with a predefined speed of at least 20 m/min, the distributor bar having a central inlet fluidly connected to a number of outlets via a main channel. The method comprises: choosing (3001) a geometry for the distributor bar and defining a set of geometrical parameters; assigning (3002) values to said parameters; creating (3003) a virtual model; simulating (3005) flow in said model by performing a Computational Fluid Dynamics simulation (CFD), taking into account (3004) a non-Newtonian shear thinning model; e) evaluating the simulated flow; building (2007) a physical distributor bar. A distributor bar, a production line, and a computer program product.

Abstract: A battery supply system comprising a display tray, an outer box and at least one inner box. The display tray includes a receiving area and a plurality of slots on sides of the receiving area. The outer box has a receptacle area and a pair of side flanges extending outwardly from the receptacle area. The at least one inner box is in the receptacle area of the outer box. The at least one inner box has at least one battery therein. The outer box is positioned in the tray by inserting the side flanges of the outer box in a pair of the slots, thereby maintaining the outer box in an upright displayed position within the tray.
