Low heat build-up capstock system and extrusion technology for solid and foamed profiles in dark colors
A weatherable, low heat build-up capstock system comprising an acrylic cap, a pigment system that is IR transparent to a greater degree than existing pigment systems, an IR reflective substrate, and an extrusion system for same.
FIBER-REINFORCEMENT OF FOAM MATERIALS, CONSISTING OF INTERCONNECTED SEGMENTS
The present invention relates to a molding made from foam, wherein at least one fiber (F) is partly within the molding, i.e. is surrounded by the foam. The two ends of the respective fibers (F) that are not surrounded by the foam thus each project from one side of the corresponding molding. The foam comprises at least two mutually bonded foam segments.
PROCESS FOR PRODUCING TYRES
A process for producing tyres including building a green tyre having two bead structures. Each bead structure includes a bead filler. The bead filler or another rigid component of the green tyre includes a final elastomeric compound produced by the following: feeding elastomeric polymer and reinforcement filler to a first batch mixing device; mixing and dispersing the reinforcement filler in the elastomeric polymer and unloading the obtained elastomeric compound; feeding the obtained elastomeric compound, along with at least 5 phr of reinforcement resin, to a continuous mixing device of intermeshing and co-rotating twin-screw or multi-screw type or of planetary type; mixing the reinforcement resin in the elastomeric compound and unloading the obtained elastomeric compound; and feeding the obtained elastomeric compound along with the components capable of facilitating the cross-linking to a second batch mixing device and mixing to obtain the final elastomeric compound. The first and second batch mixing device have two counterrotating rotors.
Light-transmissive plastic plate structure with curved surface and method for fabricating the same
The invention refers to a light-transmissive plastic plate structure suitable for vehicle sunroof with curved surface and a method for fabricating the same. By using polymer material formulation, UV resistant coating formulation and precision coating technology, the wear resistance of polymer surface of plastic substrate can be improved to the same level as glass, and the original optical and physical properties after various environmental tests can also be maintained. The plastic substrate is first formed into a curved plastic plate through a hot pressing process, and then a connecting structure is formed and fixed on the plastic plate by an insert-molding injection process, in order to replace the traditional car sunroof mechanism which is assembled by glass plate bonded with metal connecting parts. The light-transmissive plastic plate structure with curved surface comprises a lightweight polymer sunroof and a lightweight plastic connecting structure fixed to the sunroof by insert-molding injection, which can reduce the weight of traditional glass sunroof, front and rear windshield, and side window glass assembly, and is particularly suitable for use in oil-electric hybrid vehicles and pure-electric vehicles that require lightweight specifications.
ROOFING, CLADDING OR SIDING PRODUCT
This invention relates to a roofing, cladding, or siding module, comprising an underlapping region extending from a head edge of the module and an exposed region extending from a foot edge of the module. The length of the foot edge defining the length of the module. The underlapping region is adapted to be substantially covered by the exposed region of an adjacent or overlapping module when installed on a building surface. The module is formed of at least one layer of extruded material. The layer so formed comprises at least 40% w/w filler and/or reinforcement, and one or more polymer(s).
Method and apparatus for making a compartmentalized tire sealant strip
A method for making a compartmentalized sealant strip and barrier assembly 10 has the steps of co-extruding a barrier strip 9 of non-sealant elastomeric material with a plurality of projecting linear extending walls 9c and a sealant strip 11 wherein the sealant strip 11 is formed on one side of the barrier strip 9 filling the space between the plurality of projecting walls 9c to form a plurality of linearly extending rows of sealant 11 across the transverse width of the co-extrusion to form the compartmentalized sealant strip and barrier assembly 10. The step of co-extruding may further include the step of: forming the projecting walls 9c on an inclined angle relative to a plane perpendicular to the width of the assembly 10. The step of co-extruding further has the step of forming the barrier strip 9 with lateral edges 9a and 9c that extend beyond the lateral outermost sealant strips 11 on each side of the assembly 10, the lateral edges 9a, 9b being bonding surfaces to seal the sealant strip and barrier assembly 10 into an uncured rubber layer when assembled into an unvulcanized tire 2.
Method and apparatus for preparing a molded article
This disclosure relates to a method and apparatus of preparing a molded article, and more particularly to a method and apparatus of automated molding using male molds and thermoplastic sheets in which the thermoplastic sheets are systematically draped across the mold contour.
METHOD FOR MANUFACTURING A COMPOSITE PART AND COMPOSITE PART
A method for manufacturing a composite part (100) for covering, sealing, trimming, or retaining a component of a vehicle, wherein the composite part (100) has a main body (110) with a vehicle side surface (111) and is made of a first polymer, and has a mounting pin (130) configured to engage in a form fitting manner and is made of a second polymer, wherein the second polymer has a higher formability than the first polymer, comprises the steps of extrusion molding of the main body (110) and injection molding of the mounting pin (130). This is done in such a manner that the mounting pin (130) is being integrally bonded to the main body (110) on the side of the vehicle side surface (111).
Solid state drawing laminated polymer billets
Solid state draw a laminated polymer billet containing two or more polymer compositions laminated to one another to prepare an oriented polymer composition.
Method for producing shape memory anti-counterfeiting identifier
A method for producing shape memory anti-counterfeiting identifier includes the following steps: a high polymer material with a shape memory function without the need of sunshine cross-linking or chemical cross-linking is directly extruded to become sheet in an extruder or is injected to be molded in an injection molding machine, and the extruded sheet can be a planar sheet or a sheet having a surface on which concave-convex patterns or characters are formed; the above sheet is then heated to the temperature higher than the vitrification temperature and lower than the melting point temperature, and the patterns or characters are pressed on the planar sheet, or the sheet on which the concave-convex patterns or characters are already formed is pressed to become planes or other patterns and characters; the sheet is then cut into small sheets, wherein one pattern or one group of characters is implied on every small sheet, and when the small sheets are again heated to the temperature higher than the vitrification temperature and lower than the melting point temperature, they will return to the extruded state.
