A multilayer tape assembly is described which can be used with insulation jacketing and particularly for self sealing lap (SSL) applications. The tape assembly includes two adhesive layers with associated carrier and release layers in conjunction with a differential release system. Various methods of use are also described.

A profile element is useful for sealing building-structure joints, especially for sealing against sound and smoke and optionally against fire. An apparatus is useful for manufacturing such profile element and to the use of the profile element manufactured according to the invention for the acoustic, smokeproof and/or fireproof sealing of connecting joints in drywalls, especially of expansion joints.

Method and apparatus for joining at least two plastic parts.

A method for joining at least two plastic parts (1, 5) along a predeterminable common joining point using infrared radiation (IR), is characterized in that each of the plastic parts (1, 5) to be joined is heated using infrared radiation at least along the joint by means of an assignable radiation source without touching the respective other plastic part (1, 5), that the respective one radiation source is operated independently and spatially separated from at least one further radiation source, that the radiation sources emit their respective infrared radiation to the respective assignable plastic part (1, 5) without contact and following the contour of the joint, and that the degree of heating by means of the respective infrared radiation is selected such that the joint is formed when the plastic parts (1, 5) are brought together.

A seal for a vacuum lifter and method of manufacture wherein the seal has a continuous unbroken outer fluid resistant skin of elastomer which forms a boundary around a homogeneous cellular structure with no interior seams or joints.

Provided are methods and systems for manufacturing and using heat-shrink elastomeric. An example method of manufacturing a heat-shrink elastomeric element comprises providing a thermoplastic elastomeric element having a first shape; modifying the thermoplastic elastomeric element to produce a thermoset elastomeric element having the first shape; heating the thermoset elastomeric element to a temperature of at least the glass transition temperature of the thermoset elastomeric element; adjusting the first shape of the thermoset elastomeric element to produce a second shape with at least one dimension greater than that of the first shape; and cooling the thermoset elastomeric element to a temperature below that of the glass transition temperature of the thermoset elastomeric element to produce the heat-shrink elastomeric element.

A method of producing a sealing member for a fuel cell includes: setting a base material made of a modified polypropylene in a mold; bringing a hydrosilicone crosslinked ethylene/α-olefin/non-conjugated diene copolymer into contact with the base material and performing molding in the mold; and vulcanizing the hydrosilicone crosslinked ethylene/α-olefin/non-conjugated diene copolymer and at the same time, bonding the hydrosilicone crosslinked ethylene/α-olefin/non-conjugated diene copolymer and the base material by vulcanization, in the mold with a molding temperature set to a temperature that is higher than a vulcanization start temperature of the hydrosilicone crosslinked ethylene/α-olefin/non-conjugated diene copolymer and lower than a melting point of the modified polypropylene.

A seal part includes an elastic body that is in close contact with outer peripheral surfaces of a plurality of wires and an inner peripheral surface of a wire accommodation portion, and a rigid body that has an outer peripheral surface disposed to face the inner peripheral surface of the wire accommodation portion. The rigid body has a plurality of wire through holes allowing wires to coaxially pass through respectively. The elastic body includes first seal portions that respectively correspond to the wire through holes, and that are in close contact with the outer peripheral surfaces of the wires passing through the wire through holes, and a second seal portion that is in close contact with the inner peripheral surface of the wire accommodation portion in the wire accommodation portion.

A fixation device for folding a seal member includes a frame having a horizontal portion and an upright portion, a press assembly secured to the upright portion of the frame, and a nest assembly secured to the horizontal portion of the frame. The press assembly includes a handle assembly and an anvil assembly operably connected to the handle assembly. The nest assembly includes a clamping assembly, a folding assembly supported on the clamping assembly, a support assembly supported on the folding assembly, and a nest member. The support assembly includes a support plate and a seal clamp for securing a seal member.

A sealing device for sealing an opening of an apparatus. The sealing device has a head that defines a cavity and a neck that defines a passage disposed between the cavity at a first end of the neck and an aperture at a second end of the neck. The aperture is configured to collapse and expand, having a first diameter in a collapsed configuration and a second diameter in an expanded configuration. The interior surface of the neck includes an engagement interface that is configured to releasably engage with a spacer. When the engagement interface is engaged with the spacer, the neck is in the expanded configuration.

The invention includes a method of bonding a perfluoroelastomer material to first surface that includes: (a) contacting a first surface with a bonding agent comprising a curable perfluoropolymer and a curing agent; (b) curing the bonding agent to form a perfluoroelastomer material that is bonded to the first surface. In the practice of such method, the bonding agent may be a solution prepared by dissolving the curable perfluoroelastomer and the curing agent in a solvent. In an embodiment of the invention, the perfluoroelastomer material formed in step (b) is a coating layer or, alternatively, the first surface is a surface of a perfluoroelastomer member and the perfluoroelastomer material formed is a perfluoroelastomer weld.
