Composite polyether block amide (PEBA) copolymer tubes incorporate an ultra-thin PEBA layer that enables rapid moisture transfer and exchange through the tube. A composite PEBA film may include a porous scaffold support and may be formed or incorporated into the composite PEBA tube. A porous scaffold support may be coated or imbibed with PEBA to form a composite PEBA film. A composite PEBA film may be wrapped on a mandrel or over a porous scaffold support to form a composite PEBA tube. A film layer may be applied over a wrapped composite PEBA film to secure the layers together. The film layer by applied by dipping, spraying or painting.

Compositions-of-matter comprising a matrix made of one or more, preferably two or more elastic layers and one or more viscoelastic layer are disclosed. The compositions-of-matter are characterized by high water-impermeability and optionally by self-recovery. Processes of preparing the compositions-of-matter and uses thereof as tissue substitutes or for repairing damaged tissues are also disclosed.

A method of making recyclable waste contains steps of: a step of collecting so that the recyclable waste is collected and classified to industrial waste and daily use plastic; a step of crushing so that the industrial waste is crushed into granules, and the daily use plastic is made to raw materials; a step of mixing so that the granules and the raw material are mixed in a weight ratio; a step of heating and plasticizing so that the granules and the raw materials are maintained in a temperature to obtain plasticity in a flowing speed; a step of extruding so that the granules and the raw materials are extruded in a predetermined shape and a predetermined length, thus forming a body. Furthermore, the method further contains a step of cooling so that the body is cooled to solidify and to be make a recycled green building material.

A process is disclosed for combining a polysaccharide ester polymer with one or more plasticizers in a way that produces a homogeneous blend. The polysaccharide ester polymer can be in the form of particles and fed to a heated extruding device. Separate quantities of plasticizer can then be combined with the polysaccharide ester polymer particles as they are conveyed through the extruding device. Through the process of the present disclosure, a homogenous blended product can be formed that can then be used to form various articles including fibers, films, and molded articles.

A process is disclosed for combining a cellulose ester polymer with a plasticizer. The cellulose ester polymer is in the form of particles and is combined with a wetting agent and the plasticizer while mixing. The wetting agent dramatically improves the ability of the cellulose ester particles and plasticizer to form a homogeneous mixture. During melt processing, in one embodiment, the wetting agent is volatilized and does not remain in the final product.

A method of forming an oral product includes extruding a mixture, conveying the extruded mixture through one or more pairs of forming rollers, and cutting the extruded mixture into one or more oral products. The mixture can include polymer and at least one flavorant, sweetener, active ingredient, or combination thereof. The extruded mixture forms an extrudate having a predetermined cross-sectional shape. The one or more pairs of forming rollers abut to define a passage there between as each forming roller rotates. The passage has a cross-sectional shape corresponding to the predetermined cross-sectional shape. The method can be performed using a machine including an extruder, one or more pairs of forming rollers, and a cutting device.

This disclosure provides a fluorine-containing mixture and a fluorine-containing super-oleophobic microporous membrane using the fluorine-containing mixture as a raw material, as well as preparation methods and applications for the fluorine-containing mixture and the fluorine-containing super-oleophobic microporous membrane. The fluorine-containing mixture of the present disclosure comprises, by weight percentage, the following components: Component A: 50%˜90%; Component B: 3%˜25%; Component C: 0%˜35%; Component D: 0%˜3%; wherein Component A comprises high molecular weight polytetrafluoroethylene homopolymer or copolymer dispersion resin; Component B comprises one or more fluorine-containing alkyl acrylate monomers; Component C comprises one or more fluorine-free acrylates; Component D comprises high temperature free radical initiator. There's no need to add inflammable or explosive lubricating oil, making the process highly safe; and the obtained fluorine-containing super-oleophobic microporous membrane has high waterproof, air-permeable, oil-resistant and washable performance, in line with the needs of a new generation of waterproof and air-permeable protective clothing.

The present invention is directed to packaging films comprising a coextruded film having alternating individual layers of glass and plastic. These packaging films may be used for flexible food and pharmaceutical packaging. These packaging films provide excellent oxygen and moisture barrier protection while having superior flexibility.
