Polyurethane Patents (Class 428/160)
  • Patent number: 10442157
    Abstract: A method and composition for preparation of a high-elasticity polyurethane glove material and glove. The method for practicing the invention generally includes the steps of preparing an ultra-high molecular weight polyol, preparing a high-elasticity polyurethane glove material, and preparing a glove by dipping and forming. A high molecular weight polyether polyol is used in conjunction with polyurethane to increase resilience to a degree comparable with rubber material. Conventional polyurethane materials lack flexibility and do not allow for significant elongation or rebound. The material of the present disclosure may be used for medical applications and modifies polyurethane material to achieve properties similar to rubber materials. The polyurethane material resulting from the method according to the present disclosure has excellent biocompatibility and may be widely used in the medical field.

    Abstract: Disclosed herein is a composite structure for deflecting and spreading kinetic energy transmission after various types of impacts utilizing foam structures having graded properties. The structure has a first composite layer, composed of a discrete reinforcement and a continuous binder. The helmet receives contact of an object that transfers kinetic energy to a first composite layer. The helmet uses a second composite layer adjacent to the first composite layer designed such that the second composite layer compresses and expands into an expansion zone in the second composite layer. The second composite layer has expansion structures with a graded modulus such that the material at the tip of an expansion structure has a low modulus and the modulus in the expansion structure increases as it moves from the tip to the base of the expansion structure.

  • Publication number: 20140342126
    Abstract: A massaging floor mat includes a layer of gel that penetrates into the cells of a layer of memory foam. The layer of foam sits on a foundation layer of hard plastic. A plurality of protrusions are distributed over the upper surface of the foundation layer. The protrusions provide a massaging sensation to the user of the mat. The protrusions also hold the layer of foam in place obviating the need to glue the foam to the foundation layer. The gel is spread over the foam as the foam moves along a conveyor belt. The gel is then cured using hot air. The foundation layer is held in place in an indentation of a bottom cover of flexible plastic without using any glue. A top cover is placed over the layer of gel, and the peripheries of the top and bottom covers are attached to each other using high-frequency welding.

  • Patent number: 8623494
    Abstract: Disclosed is a protective cover for an electronic device that is made from an elastomeric material that simultaneously provides cushioning that would otherwise be provided by a softer, thicker material, while utilizing a single, denser material that provides a slim profile and has sufficient density to conform well to the electronic device and prevent the transmission of impacts with hard surfaces directly to the electronic device. Although a denser material is used for the protective cover, recesses are formed in thicker portions at impact points that create compressible ribs. The ribs provide softer, cushioned portions of the cover in the impact areas, which are capable of absorbing the shock and energy of impacts. Other protective covers have a uniform thickness.

The coating has the correct chemical activity to chemically bond MCU at the molecular level during the standard curing reaction. The coating provides an intermediated property layer to improve cyclic fatigue bonding performance, and bond effectively during molding and manufacturing operations.

  • Publication number: 20110091689
    Abstract: The object of the present invention is to provide a polyurethane foam for flame lamination which has an excellent balance between adhesiveness to a fabric comprising synthetic fibers or natural fibers, a leather or the like and residual compression strain and has an excellent wet-heat resistance, and a laminated body including a foamed material layer consisting of the polyurethane foam. The polyurethane foam for flame lamination is characterized by being produced using a foam raw material containing a polyol such as a polyether polyol, a polyisocyanate, a foaming agent, a foam control agent, an amine-based catalyst and a urea compound such as urea and azodicarbonamide.

  • Patent number: 7923088
    Abstract: A frictional holding pad for removably attaching items, such as a cell phone or sunglasses, to a vehicle surface, such as a dash or console, to allow storage of items on the pad to prevent the items from shifting or sliding due to the movement of the vehicle. The holding pad includes a top surface having an uppermost contact surface configured to contact and frictionally cling to the item and a bottom surface having a lowermost contact surface configured to contact and frictionally cling to the vehicle surface. The top and the bottom surfaces are configured to provide a greater frictional engagement between the lowermost contact surface and the vehicle surface than the uppermost contact surface and the item. Protrusions or indentation can be formed in the top and bottom surfaces of the pad.

  • Publication number: 20110067183
    Abstract: A cushioning device with an upper foam layer and a lower positioned foam layer, with the upper foam layer having multiple thickness zones defined by different height projections from one zone to another as to provide a thickness variation pattern, one side of the upper foam layer is less contoured when not yet assembled in the cushioning device and a second side is comprised of the multiple thickness zones such that, upon connection of the multiple thickness zones to the lower positioned foam layer, the height differential along a length of the upper foam layer is transmitted as to form a non-planar, crown configuration in the upper surface of the upper foam layer. A method includes roller contouring different height and shaped projection zones including zones with different ratios of peak height to overall zone height.

  • Patent number: 7910188
    Abstract: A frictional holding pad removably attaches handheld items, such as a cell phone, to a surface, such as a dash, to allow storage of handheld items on the surface with the pad to prevent the items from shifting or sliding due to the movement of the support surface. A smoother application side of the pad clings to the handheld item by specific or mechanical adhesion, and a contoured exposed side of the pad clings to the surface by specific or mechanical adhesion. The smoother application side of the pad can have a greater surface area than the contoured exposed side so the pad remains with the handheld item when removed from the surface. Indicia can be formed on the pad. The pad can be translucent or transparent. The pad can include an expanded vinyl material or a polyurethane material.

  • Patent number: 7785692
    Abstract: A floormat arranged to shed fluids has a topside and an underside. The floormat is placed where a user is expected to stand during a procedure. Fluids released during the procedure are allowed to fall onto and be shed off the floormat before being removed. The floormat may be discarded before starting another procedure. The mat is formed, at least in part, of compressible and resilient material. The topside of the mat has a spaced plurality of channels. In one instance, each of the channels has a floor sloping in opposite directions from a central peak. In another instance, the mat has a tapered apron bordering a central section that is convexly crowned to shed fluids. In other embodiments the topside of the central region is substantially flat except for the spaced plurality of channels. The floormat may be placed where an operator is expected to stand during the procedure. Fluids that fall onto the floor mat are shed therefrom and then removed. The floormat is discarded before starting another procedure.
