The invention is directed to a crosshead die for the extrusion of a profile, such as a uniform ply coat for a tire. The crosshead die is used with an extruder, and includes a body. An inlet is formed in the body, and is in fluid communication with the extruder. An outlet and a flow channel are also formed in the body. The flow channel extends between the inlet and the outlet, and is bounded by an upper wall, a lower wall, a first side wall, and a second side wall. The flow channel is formed with a bend and a cross section that includes a trapezoidal shape to align the flow of elastomer with the center of the flow channel.

A breathing circuit component includes an inlet, an outlet and an enclosing wall. The enclosing wall defines a gases passageway between the inlet and the outlet. At least a region of the enclosing wall is formed from a breathable material that allows the passage of water vapor without allowing the passage of liquid water or respiratory gases. The breathing circuit component may be the expiratory limb of a breathing circuit.

A diffuser membrane and a method for manufacturing the same are provided. In the method for manufacturing, a first material is heated and extruded to form a base layer and a second material is heated and extruded to form a coating layer. The base layer and coating layer may be extruded substantially simultaneously in a coextrusion process. Accordingly, the coating may be applied to the base layer in a manner that optimizes the bonding between the two layers and provides the ability to control the thickness of the coating layer. Alternatively, the base layer is formed initially and the coating layer is subsequently formed thereover. The first and second materials have differing properties. The first material may comprise polyurethane and the second material may comprise polyurethane and PTFE.

A method for manufacturing a raw blank of a tyre includes using a calender to produce a ply. The calender includes two rollers with a gap situated therebetween. A ply that includes a first rubber material is formed in the gap of the calender, with a bead of the first rubber material being formed upstream of the gap. The bead and the gap of the calender are fed with a second rubber material, different from the first rubber material, to form at least one insert in the ply.

Described herein is flooring formed of an eco-friendly material, where the flooring has excellent heat resistance, durability, abrasion resistance and dimensional stability, and is formed of a non-PVC material and thus is recyclable via an extrusion processing at the time of disposal after use. Specifically, eco-friendly flooring is described in which a coating layer, an overlayer having ionomers, a printing layer, at least one middle layer, and at least one underlayer are laminated in order, where the overlayer of the flooring has ionomers, at least one of the middle layer and the underlayer has a thermoplastic polyolefin-based resin, a styrene-based resin, oil, and a filler, the thermoplastic polyolefin-based resin is contained in an amount of 50 to 150 parts by weight with respect to 100 parts by weight of the styrene-based resin, and the styrene-based resin may contain 25 to 45% styrene.

The present disclosure relates generally to polyurethane matrix composite materials, for example, suitable for making an exterior cladding product for houses and other buildings. The present disclosure relates more particularly to a polymer matrix composite material including a polyurethane matrix and an inorganic filler in a range from 45% to 85% by weight of the composite material. The inorganic filler includes a first substance from the group consisting of calcium carbonate, sand, talc, kaolin clay, dolomite, feldspar and mica and any mixture thereof, and fly ash, and/or an iron oxide in a range from 0.5% to 7% by weight of the inorganic filler.

An easy peel sealant film includes at least a support layer and a peel layer. The support layer has a composition which contains 100 to 70 mass % of a linear low-density polyethylene, and 0 to 30 mass % of a propylene homopolymer. The peel layer has a composition which contains 40 to 60 mass % of a low-density polyethylene, 10 to 20 mass % of a high-density polyethylene, and 20 to 50 mass % of a propylene homopolymer. The propylene homopolymer in the support layer and the propylene homopolymer in the peel layer have a melt flow rate of 1 g/10 min to 9 g/10 min.

A molding apparatus that adsorbs thermoplastic resin extruded in a sheet form from an extruding machine, onto a cavity of a mold, and shapes the thermoplastic resin into a shape according to the cavity is provided. The molding apparatus may include a frame that is positioned on a periphery of the mold and is movable relative to the mold, wherein a suction part for suctioning the thermoplastic resin is provided in a contact surface of the frame to contact the thermoplastic resin, and the suction part is provided in a linear shape along with a longitudinal direction of the frame positioned on the periphery of the mold.

A light diffusion plate is configured to be assembled with a blue light source module having blue Mini LEDs to form a white light backlight module. The light diffusion plate is added with organic dyes with light-emission wavelength of 490-650 nm in order to convert the blue light into white light. The light diffusion plate is made by a foaming extrusion process and contains a plurality of micro-bubbles with a size of 60-400 μm and a weight-reduction ratio of 15-25% for improving the uniformity of white light and resolving the MURA problem. The size of micro-bubbles is controlled by reducing the temperature of at the exit end of the T-die head, such that the wavelength of the white light emitted from the light diffusion plate can be narrower to achieve the effect of wider color gamut display.
