摘要:
A method for producing a weather strip including an extrusion molded extrusion molded portion, an injection molded portion which is formed by a molding device having a plurality of mold members and connects both ends of the extrusion molded portions in a straight line shape, a mounting base portion which is mounted on a circumferential edge of an opening of a body or a circumferential edge of an opening/closing member for opening and closing the opening, and a hollow sealing portion which protrudes from the mounting base portion, and is pressed against an opposite member when the opening/closing member for opening and closing the opening is closed.

A dielectric weldable material includes a blend of at least two components including an inert polymer and an elastomeric polar polymer. A method of forming a bond includes providing a substrate having a first end and a second end, wherein the substrate includes a blend of at least two components including an inert polymer and an elastomeric polar polymer. The method further includes bonding the first end and second end of the substrate with high frequency electromagnetic energy.

The invention is a pipe joint that is particularly suitable for joining pipes composed of materials having a low surface energy and excellent resistance to solvents. The major components are an extrudable adhesive; a first pipe having a socket with an inside diameter, where said socket has a mouth, a self-centering bottom, and a substantially cylindrical wall with an inlet, an outlet, and an inner annular channel; a second pipe having an insertion section with an end and an outer annular channel, said second pipe having an outside diameter that is less than the inside diameter of the socket, where the difference in diameters defines a gap and where the outer annular channel lines up with the inner annular channel therein forming an interlocking keyway; and a flanged annular ring, where said annular ring has an inside diameter that enables it to be slid over the second pipe and a thickness that is comparable to the gap, and where the flange has a width that is sufficient to cap the mouth of the socket. When fully formed, the adhesive has changed to a solid material that substantially fills the gap and the interlocking keyway, and serves as a mechanical key in the interlocking keyway. The adhesive is preferably an alkyl borane adhesive

A vent member (10) includes: a support body (4) having a vent passage (a vent hole (3)) between an interior space (22) and an exterior space (24) of a housing (20); a gas-permeable membrane (2) disposed on the support body (4) to close the vent passage (3) on the side of the exterior space (24); a cover (6) attached to the support body (4) to protect the gas-permeable membrane (2); and a laser welding portion (12) that joins the cover (6) and the support body (4) together. For example, the support body (4) is made of a first material that relatively easily absorbs laser light for forming a laser welding portion (12). The cover (6) is made of a second material that absorbs less laser light than the first material and can transmit laser light.
摘要:
The invention relates to the use of spherical metal particles, which are free of antimony and/or antimony-containing compounds, as a laser marking agent or laser weldability agent in a plastic, wherein the particle size distribution of the spherical metal particles, as determined by means of laser granulometry, in the form of the volume-averaged cumulative undersize particle size distribution, has a D99 value of
摘要:
A tube-in-tube assembled parison for preparation of an elongated medical device. The parison if formed by assembling in tube-in-tube fashion a first tube of orientable polymer material and a second tube formed of orientable polymer material disposed around the first tube, with an adhesive tie layer disposed between the first and second tubes. The tubes are brought into contact to form a unitary parison. The adhesive may allow movement between the polymer layers during balloon blowing. The first tube, or the second tube, or both, may have been longitudinally pre-stretched after formation thereof but before assembly of the parison.
摘要:
Stiff and soft materials each provide certain advantages when used in the manufacture of separable insulated connectors, such as elbow and T-body connectors. Utilizing a shell or an insert that includes one section made from a stiff material and one section made from a soft material can provide a separable insulated connector that capitalizes on the advantages associated with both types of materials. The stiff materials and soft materials can be placed strategically on the shell or insert of the separable insulated connector to maximize the advantages of each material. For example, the stiff material can be used to form a section of the separable insulated connector where strength and durability is most desirable, and conversely, the soft material can be used to form a section of the connector where flexibility is desirable. A relatively stiff band can be provided around a relatively soft portion of a connector.

A composition for a polarization film including a polyolefin component including polypropylene and a polyethylene-polypropylene copolymer; and a dichroic dye.
摘要:
The invention relates to a membrane, in particular a gas storage membrane, comprising at least two individual membrane webs that are connected to each other by at least one seam construction, wherein each individual membrane web (4, 4′) comprises at least one elastomeric layer and at least one outer layer based on PTFE. The invention further relates to a method for producing such a membrane.
