A method for producing a microporous material comprising the steps of: providing an ultrahigh molecular weight polyethylene (UHMWPE); providing a filler; providing a processing plasticizer; adding the filler to the UHMWPE in a mixture being in the range of from about 1:9 to about 15:1 filler to UHMWPE by weight; adding the processing plasticizer to the mixture; extruding the mixture to form a sheet from the mixture; calendering the sheet; extracting the processing plasticizer from the sheet to produce a matrix comprising UHMWPE and the filler distributed throughout the matrix; stretching the microporous material in at least one direction to a stretch ratio of at least about 1.5 to produce a stretched microporous matrix; and subsequently calendering the stretched microporous matrix to produce a microporous material which exhibits improved physical and dimensional stability properties over the stretched microporous matrix.

An optical resin formed body manufacturing method includes: (i) depressurizing an inside of a container holding a molten optical resin; (ii) pressurizing the inside of the container holding the molten optical resin; and (iii) shaping the optical resin taken out of the container into a given shape. The steps (i) and (ii) are sequentially performed once each or are alternately performed two or more times each. In the step (i), a duration t1 [min] of the depressurization of the inside of the container is set such that the duration t1 and a viscosity .Math.1 [Pa•s] of the molten optical resin satisfy a relation .Math.1/t1 < 200. In the step (ii), a duration t2 [min] of the pressurization of the inside of the container is set such that the duration t2 and a viscosity .Math.2 [Pa•s] of the molten optical resin satisfy a relation .Math.2/t2 < 200.

A single-screw extruder for changing a morphology of superabsorbent polymer gel. The single-screw extruder has an input aperture, a channel, a screw and an output aperture. The screw in the invention has a first pitch value of a pitch of the screw flights along the conveying zone of the channel and, following in conveying direction, has a second pitch value of the pitch of the screw flights along the conveying zone of the channel, where the second pitch value is smaller than the first pitch value.

A method for thermoforming an article includes extruding a sheet of material, conditioning the sheet with a roller, thermoforming the sheet to provide a web, and cutting the web to provide the article.

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.
