A slider window assembly for a vehicle includes at least one fixed window panel and a movable window panel that is movable along an upper rail and a lower rail at the at least one fixed window panel between a closed position and an opened position. The upper rail includes a channel, and a filler is disposed in the channel of the upper rail. The filler includes a filler body having opposite side walls, and the filler includes lips established along respective ones of the side walls. The lips are extruded onto and along the filler body. The lips include a compressible and flexible material and provide a dampening and cushioning function at the movable window panel when the movable window panel is disposed in the channel of the upper rail.

A molding apparatus for a loop structure includes a molding die within which both ends of an elongated structure are located in such a manner that the ends are in contact with each other, the elongated structure being formed of a rubber to which a peroxide cross-linking agent is added; a liftable housing including a lower part having an opening, the housing defining a containment space within which the molding die and the elongated structure are located when the housing is lowered; a degassing device configured to depressurize and degas the containment space; a heating device configured to heat the molding die in the containment space; a pressure device configured to pressurize the ends of the elongated structure with the use of the heated molding die in the containment space to proceed cross-linking reaction of the rubber, thereby bonding the ends of the elongated structure; and an elevating device configured to lift and lower the housing.

A device for producing sealing rings made of an endless-material. The device includes a feeder unit which conveys and positions the endless-material in a cutting position, a cutting unit which cuts off a section of the endless-material, a gripper unit which grips and displaces the endless-material or the section of the endless-material and which controls a displacement of at least one free end of the section of the endless-material along a predefined path of motion in and/or out of a wetting position, a control device connected with the feeder unit, the at least one gripper unit and/or the cutting unit, and a feeding device for a bonding fluid. The feeding device is connected with the control device and is arranged so that the bonding fluid is deposited in a controlled manner on the at least one free end of the section of the endless material in the wetting position.

Pellet-stable olefinic copolymer bimodal rubber is made using parallel reactors, with one reactor synthesizing higher molecular weight (MW) rubber with dual catalysts, with an improved molecular weight split ratio and an improved composition distribution of the moderate and ultra-high MW components, while another reactor synthesizes random isotactic polypropylene copolymer (RCP). The effluents are reactor-blended and result in pellet-stable bimodal rubber (P-SBR), which may be pelletized. When making thermoplastic vulcanizates (TPVs) with P-SBR, the need to granulate rubber bales and subsequently use talc, clay, or other anti-agglomeration agents to prevent granulated rubber crumbs from agglomerating are eliminated. TPVs made with P-SBR have vulcanized rubber particles that are smaller and more uniform in size, resulting in TPVs with higher particle counts and more thermoplastic ligaments between the particles, with such ligaments being made stronger by the added RCP. Such thus-produced TPVs have a lower hysteresis and flexural modulus, and better elastic properties.

A process for the continuous and solvent-free production of a pressure-sensitive adhesive based on solid EPDM rubber, the pressure-sensitive adhesive produced thereby, and an adhesive tape containing the pressure-sensitive adhesive. The pressure-sensitive adhesive is produced in a continuously operating assembly in the form of a planetary roller extruder having a filling section and a compounding section, the compounding section consisting of at least two coupled roller cylinders, by

a) feeding the solid EPDM rubber and any further components into the filling section of the planetary roller extruder,
b) transferring the components from the filling section into the compounding section,
c) adding liquid EPDM rubber, plasticizer, tackifier resin, and any further components to the compounding section, and
d) discharging the resultant pressure-sensitive adhesive,
which process comprises feeding the solid EPDM rubber as a melt into the filling section.
