CLOSED-CELL POLYURETHANE STRUCTURE METHOD AND SYSTEM
A container, that includes a transparent portion, which reveals an interior portion of the container, an access aperture communicating with the interior portion of the container, and a lid adjacent the access aperture. A first liquid component is placed into the interior portion. A second liquid component is poured into the interior portion. The lid of the container is closed to fully enclose the first and second liquid components. The components are agitated until the first and second liquid components are a mixture of uniform color, without an appearance of marbling and swirling, when viewed through the transparent portion of the container. The lid is opened to expose the mixture of uniform color. The mixture of uniform color is poured from the container into a receiving structure. The mixture of uniform color is transformed into a closed-cell polyurethane structure within the receiving structure.
COVER FOR A SPA AND METHOD OF MANUFACTURING A COVER
A method of manufacturing a cover for a spa includes the steps of vacuum molding a first shell member and a second shell member, bringing the first and second shell members into registration with one another to define a hollow cavity therebetween, and injecting a foam into the hollow cavity, wherein the foam is configured to bond with the shell members to create a unitary structural part that provides increased strength and rigidity.
Injection molded product and method for manufacturing same
In an injection molded product of the invention, an unevenness forming portion having unevenness formed by thermal expansion of thermally expandable capsules is formed. The injection molded product includes a highly expanded portion that is formed at a surface side of the unevenness forming portion in a thickness direction of the injection molded product and in which the thermally expandable capsules are thermally expanded, and a main body portion that is a portion adjacent to the highly expanded portion in the thickness direction and in which the thermally expandable capsules are substantially not thermally expanded. The thickness of the highly expanded portion is a half or smaller than the thickness of the injection molded product in the unevenness forming portion, and a polymer material of the highly expanded portion and a polymer material of the main body portion are the same polymer material.
STAND FOR HAY BALES AND METHOD
This invention relates to a stand for supporting hay bales above the ground. The inventive hay stand The device is formed in the shape of an rectangular prism or cuboid from an inert plastic, closed-cell, polyurethane structural foam that will not allow water or air to move through it. The devices are constructed by pouring the structural foam material into forms that are constructed to yield the desired shape. The structural foam has two chemicals that are mixed and then poured into the form. The foam then heats and rises to take on the shape of the interior of the form. Once the foam is fully cured, the forms are removed, and the device is ready for use. Hay stands constructed in accordance with the present invention are useful for protecting hay bales from spoilage due to ground moisture.
Mechanical reticulation of polymeric-based closed cell foams
Polymeric based closed cell foams, such as shape memory polymer foams, contain bubbles. Making these bubbles continuous is called reticulation. Disclosed are embodiments of a device and method to controllably reticulate polymer-based closed cell foams by puncturing the membranes of these polymer-based closed cell foams.
MOLDED FOAM
The present invention relates to molded foam having no hollow space caused in a plate-shaped portion. The molded foam comprises a tube body and a plate-shaped portion joined to the outer side of the tube body. The expansion ratio of the molded foam is lower than two, and a value of a thickness B/a thickness A as a relationship between the thickness A of the tube body at the periphery of a point joined to the plate-shaped portion and the thickness B of the plate-shaped portion is less than 2.82.
MULTI-LAYER POLYMER FOAM FILM FOR PACKAGING APPLICATIONS AND THE METHOD OF MAKING THE SAME
A multilayer foam film suitable for direct and non-direct food contact and aseptic packaging application is disclosed.
Headrests
A vehicle headrest includes an electro-acoustic transducer and an acoustic enclosure that supports the electro-acoustic transducer. A unitary foam member is coupled to the acoustic enclosure. The foam member has regions of contrasting firmness including a first region having a first firmness and a second region having a second firmness that is greater than the first firmness. The second region defines a speaker grille that is configured to overlie the electro-acoustic transducer.
COMPOSITE THIN WINGBOX ARCHITECTURE FOR SUPERSONIC BUSINESS JETS
An apparatus including one or more panels including an outer face sheet comprising a plurality of first composite materials; an inner face sheet comprising a plurality of second composite materials; and a plurality of foam pieces disposed between the outer face sheet and the inner face sheet, wherein the foam pieces reduce warping of the panels.
LOW DENSITY POLYETHYLENE FOAM WITH EVACUATED CLOSED CELLS AND HAVING TORTUOUS PATHS OF THERMAL AND ACOUSTIC CONDUCTIVITY
A perforated expanded low density polyethylene foam layer, wherein in the expanded low density polyethylene layer at least 80% of the blowing agents are dissipated from closed cells within the expanded low density polyethylene layer forming evacuated closed cells whereby a partial vacuum is formed within the closed cells of the low density polyethylene layer.
