    Abstract: Coextruded films provide cross directional zoned multiple components side-by-side to one another. Systems and methods relate to coextruding such films. During coextrusion, a first polymer conjoins with a second polymer while a temperature differential is maintained between the first and second polymers. This temperature differential is selected to reduce a difference between the viscosities of the first and second polymers making the viscosity of the first polymer close enough to the viscosity of the second polymer to avoid separation upon coextrusion. Further, the films may form a layer in subsequent lamination to other material layers.

    Abstract: Exfoliation of graphene from graphite using multilayer coextrusion is generally disclosed. In some example embodiments, graphite may be dispersed within a first processing material, and the first processing material and a second processing material may be co-extruded through a plurality of series coupled layer multiplication dies to exfoliate graphene from the graphite. The graphene may be separated from the resulting multi-layered material. In some example embodiments, graphite flake and/or expanded graphite may be dispersed within the first processing material.

  • Patent number: 8632706
    Abstract: A single-sided, slip resistant, self-adhesive material is produced using a blown film process which produces a film having an interior layer capable of being treated or coated to accept a pressure sensitive adhesive, a middle layer of flexible polyolefin and an exterior polyolefin elastomer layer in combination with a blowing agent to produce a single-sided slip resistant material. A number of in-line rollers are provided after a pair of rollers, which form part of a machine direction orienter (MDO) that is used in line in the manufacturing process to heat, and then cool and condition (anneal and relieve any stresses and/or thickness inconsistencies) the film prior to the film being coated on one side with a pressure sensitive adhesive.

  • Patent number: 8623250
    Abstract: The invention relates to a method of manufacturing a multilayer object in synthetic resin (9) by compression molding a dose of molten multilayer resin (1) comprising at least one functional layer (2,20), each layer of the dose being in the molten state at the time of compression; the method consisting at least in co-extruding the resins through a die, in cutting the extrudate periodically in order to obtain a dose (1), then in depositing the dose (1) in the molten state in the cavity of a mold; the method thereby defining, within the dose, an extrusion direction and an arrangement of the functional layer (2,20) parallel to the extrusion direction; the method being characterized in that the dose is compressed along a compression axis (16) which intersects the extrusion direction, so as to introduce, into the flow of the layers, asymmetry with respect to the compression axis (16).

  • Publication number: 20130305612
    Abstract: A sealing member for a vehicle opening includes a first co-extrusion layer formed from a first elastomeric composition, a second co-extrusion layer formed from a second elastomeric composition, and a third co-extrusion layer formed from a thermoplastic vulcanizate composition. The first co-extrusion layer defines a mounting channel, a window channel, and a front face spaced from the mounting channel and the window channel. The second co-extrusion layer has a portion disposed on the front face of the first co-extrusion layer and a sealing lip disposed on the first co-extrusion layer abutting the portion and extending away from the first co-extrusion layer towards a distal end. The third co-extrusion layer is disposed on the portion and the sealing lip of the second co-extrusion layer for covering segments of the second co-extrusion layer that are visible from an exterior of the vehicle.

  • Publication number: 20130292871
    Abstract: Disclosed are a feedblock multiplier with thickness gradient variation, a feedblock system, a method, and multilayer structure made by the method. The feedblock multiplier combines the functionalities of feedblock and multiplier conventionally used for producing the multilayer structure. The feedblock multiplier includes an input section for feeding fluid materials. A feedblock section is included for dividing the fluid delivered into multiple channels correspondingly. The fluids in the channels are segmented into two or more fluid segments by a segmenting section. The each fluid segment is delivered through corresponding channel-conversion section with thickness-gradient variation in the feedblock multiplier. Each channel-conversion section includes multiple channels with configurable positions. The fluids are then combined in a multiplier section for producing the multilayer structure with overlapped layers. The multilayer structure is outputted from an extruding section.

  • Patent number: 8523551
    Abstract: An unvulcanized rubber extruder that realizes extrusion forming of an unvulcanized rubber extrudate ensuring manufacturing of a high-quality tire without any increase of tire manufacturing steps. In the vicinity of left side end portion, in the drawing, of unvulcanized rubber (A) (rubber chafer part), unvulcanized rubber (B) flows along parallel wall (56) on the downside of main rubber flow channel (34) and flows along second inclined surface (38) on the upside of the main rubber flow channel (34). Simultaneously, apart from the main flow of the unvulcanized rubber (B), portion of the unvulcanized rubber (B) is extruded out in the direction perpendicular to auxiliary rubber flow channel (44) (arrow B direction). Accordingly, in the left side end portion, in the drawing, of unvulcanized rubber (A) (rubber chafer part), it appears that the upside and downside are shut in by the flow of the unvulcanized rubber (B).
