Abstract: A method for preparing an unsintered PTFE film capable of being continuously formed and with uniform density distribution and high density. The method for preparing the unsintered PTFE film includes filling a mixture obtained by adding a forming aid to PTFE fine powder in an extrusion forming die, extruding the filled mixture from the extrusion forming die to produce an extrusion forming body, rolling the extrusion forming body with a roll to produce a forming aid-removed film without the forming aid, and pinching the forming aid-removed film into a pinch roll made of a rubber roll formed by coating rubber on a metal shaft core at room temperature and compressing the forming aid-removed film so that thickness of the forming aid-removed film is reduced and density thereof is above 2.0 g/cm3.

Abstract: An improved method and an improved device for producing a monoaxially or biaxially stretched plastic film are distinguished, inter alia, by the following features:
In the intermediate space (Z) tapering in a wedge shape to the contact line (111, 11′) between the melt film or plastic film (5, 5′) and the roller jacket (9) spaced apart therefrom or the roller surface (9′) spaced apart therefrom of the cooling roller (1, 1′), at least one device for preventing precipitation of condensate (K) in the intermediate space (Z) is used and is designed such that precipitation of condensate (a) on the underside (5a) of the melt film or plastic film (5, 5′) facing the roller jacket (9) or on the roller jacket (9) of the cooling roller (1, 1′) is prevented, and/or a condensate (K) which has precipitated there evaporates or vaporises, and/or condensate disposed in the intermediate space (Z) is transported away, suctioned off, or blown out and/or runs out to the side.

Abstract: An integral geogrid includes a plurality of interconnected, oriented strands having an array of openings therein that is produced from a coextruded multilayer polymer sheet starting material. By virtue of the construction, the coextruded multilayer sheet components provide a crystalline synergistic effect during extrusion and orientation of the integral geogrid, resulting in enhanced material properties that provide performance benefits to use of the integral geogrid in soil geosyuthetic reinforcement.
