20210394692 · 2021-12-23 ·

The invention relates to a panel with a porous shell and a spring layer, part of which enters the shell and produces an integrated sealed barrier. The foam of the shell is an integral skinned foam and the shell has a core with a substantially homogenous density and a porous skin. The overall density of the shell is between 150 and 350 kg/m3. The skin thickness is between 0.3 and 2 mm and has a permeability such that a 2 mm thick foam strip cut into the shell and integrating the skin exhibits air flow resistance of between 250 and 2000 N.s.m−3.

Resin molding device and method

A movable mold includes a main mold part, a separate mold part separate from the main mold part, and a relative movement mechanism moving the separate mold part relative to the main mold part in a driving direction of a mold driver.

PROCESS FOR MOULDING POLYMERIC FOAM CORE SANDWICH ARTICLES
20220126489 · 2022-04-28 · ·

A process for producing a polymeric article is provided that includes: sequentially filling a female mould (11) with a first, second, and third batches, wherein the first and third batches include first and third polymeric materials (1p, 3p), and the second batch includes a second polymeric material (2p) and a blowing agent (2b), closing the thus filled cavity with a lid (12) to form a mould defining a closed cavity (10c) of constant volume in time, heating the mould (10) to a processing temperature, to melt the first, second, and third polymeric materials (1p-3p) and to expand the second polymer agent by activation of the blowing agent, cooling and removing the lid (12) to open the cavity and extracting the polymeric article. At least the second polymeric material (2p) includes at least 50 wt. % of recycled polymer in the form of shredded flakes.

FOAM PRODUCT AND MANUFACTURING METHOD THEREOF
20220118661 · 2022-04-21 ·

The present invention disclosed a foam product and the manufacturing method thereof. The foam product includes a foam core, an outer skin, a cross-linked foam sheet and a bottom plate, wherein the aforementioned layers are all pre-made. The cross-linked foam sheet is laminated onto a bottom surface of the foam core, and the outer skin is then laminated onto a top surface and a periphery of the foam core. Lastly, the bottom plate is laminated onto the cross-linked foam sheet, wherein, the bottom plate has a non cross-linked foam sheet and a non-foam plastic plate, so that when the bottom plate is laminated onto the crossed-link foam sheet, the non cross-linked foam sheet is sandwiched between the cross-linked foam sheet and the non-foam plastic plate.

HYDROPHILIC COMPOSITE
20210347988 · 2021-11-11 ·

Hydrophilic composite structures are made by impregnating a 3DL structure with a polyurethane foam formulation and curing the formulation to produce a foam that occupies the spaces in the 3DL structure. The composite structures have an unusually good capacity for retaining water even when under compressive forces. They also exhibit at most moderate swelling when saturated with water. The foam is useful as a layer of a water containment system such as a green roof or blue roof system.

A METHOD OF FORMING A BUILDING
20210348400 · 2021-11-11 ·

There is currently a demand for buildings that can be formed both quickly and economically. These buildings require the addition of heat insulation to walls or roofs because the materials from which they are otherwise formed have insufficient ability to protect against the cold. This can add undesirable expense and slow down production rates. A method is disclosed of forming a building that addresses this problem. The method comprises arranging a door frame, window frame or edge support frame at a mould and spraying a first spray material onto the outside of the mould so that the spray material sets generally in the shape of the mould and substantially embeds the frame. The first material and the frame is removed from the mould and a second different spray material is sprayed onto the first spray material to provide a skin therefor.

Seat element panel

A back panel of a motor vehicle seat element successively includes a layer of paint, a layer of non-expanded foam, at least one thermal device, and a layer of expanded foam.

Self rising board molding

A three-dimensional component is produced in a simplified molding operation. Expandable substrates, which are referred to as blanks, are created by compressing thermobonded nonwovens after heating the binder material above its melting temperature, and then cooling the compressed nonwovens so that the binder material hardens and holds the fibers of the nonwoven together in a compressed configuration with stored kinetic energy. Boards can be formed by laminating two or more blanks together and/or by laminating the blanks with other materials, including non-expendable materials. A mold for the component to be manufactured can be partially filled with a number of boards (or blanks) in a stacked, vertically, adjacent or even random orientation. In addition, the boards or blanks may be cut to create desired shapes of parts that can be placed in the mold.
