A method of and apparatus for sinter forging a precursor powder to form a film may reduce or eliminate the stress in the film and may facilitate processing of continuous length of films such as ceramic films for use in batteries. The precursor powder can be provided on a substrate and is simultaneously heated and pressed in a pressing direction parallel to a thickness of the film so as to sinter and densify the precursor powder to form the film in a sinter forging area. Notably, in a plane perpendicular to the pressing direction, there are no lateral constraints on the sinter forging area or the material received therein.

This document describes systems and processes for forming synthetic molded slabs, which may be suitable for use in living or working spaces (e.g., along a countertop, table, floor, or the like).

A polyolefin multilayer microporous film includes a first layer containing ultra-high molecular weight polypropylene and high density polyethylene, formed on each side of a second layer containing ultra-high molecular weight polyethylene and high density polyethylene. In the first layer, 30% to 60% thereof is a region in which the polypropylene content is less than 20% as determined by AFM-IR from the displacement of an AFM cantilever measured between when laser is irradiated at 1465 cm-1 and when laser is irradiated at 1376 cm-1. For regions wherein the polypropylene content is 20% or higher, the mean of the maximum diameters is 0.1 μm to 10 μm. At 90° C., the film has an elongation at puncture of 0.40 mm/μm or greater.

An ethylene interpolymer product comprises from 40 to 80 weight % of a first ethylene interpolymer having a molecular weight distribution index of Formula (I), and, from 20 to 60 weight % of a second ethylene interpolymer having a molecular weight distribution index of Formula (II), wherein said ethylene interpolymer product is characterized by a dilution Index, Y.sub.d, greater than 0, and, a solid-to-liquid transition temperature not greater than 112° C. The ethylene interpolymer product may be further characterized as having a weighted Rheological Adhesion Parameter, Rh.sub.adh, greater than 1.5. Films made from the ethylene interpolymer product composition have a hot tack seal onset temperature less than 90° C. and a hot tack window at 2.5N measured on a 2 mil blown film no less than 30° C.

A method for the production of an elastic laminate, comprising the following steps in a same production line: to coextrude a first web of elastic film (F) with at least three layers (F1, F2, F1), comprising at least two different polymer materials, to feed contemporaneously said coextruded first elastic film (F) web and two second nonwoven webs (T1, T2) to a thermal, binding calender (14), wherein the first elastic film web is arranged between said two second nonwoven webs when entering the calender; wherein said first elastic film web, during the movement from the coextrusion step to the thermal binding step, passes from a melted state, in the coextrusion step, to a solidified and cold state when entering the calender, to join, through spot welding in said calender, said second nonwoven webs with respective opposite outer layers of said first elastic film web, thus producing an intermediate web (P1), to stretch mechanically said intermediate web according to a direction transverse to the same web.

A method of automatically advancing a polymer cut-board, such as cellular polyvinyl chloride, through a stationary, non-spinning sealing element having a rounded or cylindrical surface that contacts and compresses a cut edge of the board to provide a sealed skin surface to the cut edge.

The invention relates to a method for the online monitoring of film quality during a production process for a plastic film, in particular a blown film or a continuously cast film, in which method the film material (1) is fed out of an outlet device (40) that is designed as a melt lug (4) by a transport device (10). The film material (1) cools on or in front of the transport device (10) and the film material (1) solidifies in front of or on the transport device (10).

A flexible film fluid-dispensing device including (A) at least one flexible film liner member having a flexibility property of from 3.6e-10 Nm to 2 Nm; (B) a rigid frame member for receiving the flexible film liner member and for removably holding the flexible film liner member in place during the flow of fluid through the flexible fluid-dispensing device; and (C) a connection means for connecting the flexible film fluid-dispensing device to the outlet feed stream of a fluid production process line; a process of manufacturing the above flexible film fluid-dispensing device; and a process for dispensing a fluid using the above flexible film fluid-dispensing device.

The present application provides a calender, a floor production line and a production method using the calender, wherein the calender comprises a calendering roller rack and a set of calendering rollers arranged on the calendering roller rack. The set of calendering rollers comprises a plurality of calendering rollers arranged in a line and not vertically. The present application changes the arrangement of the calendering rollers. The calendering rollers are arranged in a line, not vertically. This arrangement reduces the overall height of the calender, decreases the requirements of the calender on the height of the factory building and facilitates long-distance transportation by containers. Using the calender to assemble the floor production line, the height space of the factory building occupied by the production line can be saved.
