Abstract: A thin wall PTFE tube is formed from an extruded green tube. The PTFE tube includes an inner tubular surface and an opposed outer tubular surface defining a tubular wall of a first thickness. The tubular wall is compressed to uniformly reduce the wall-thickness and circumferentially orient the tube. The PTFE tube is positioned over a first elongate roller with the inner tubular surface being in contact therewith. A second roller is positioned against the outer tubular surface of the PTFE tube. The pair of rollers are counter rotated so as to circumferentially compress the tubular wall between the rollers. This results in the uniform reduction in the tubular wall from the first thickness to a lesser second thickness and a circumferential orientation otherwise not occurring in an extruded PTFE paste extrusion.

Abstract: A process for the production of coated planar moldings of thermoplastics is disclosed. The process entails extrusion of a molded body, cooling of the molding, applying the aqueous-based coating agent and drying. The coating agent, having a pH value of less than 6, contains a salt of sulfondicarboxylic diester, a water-insoluble oxide of metal or semi-metal and an acid/water mixture. It is applied to at least one surface of the molding immediately after the production of the molding and with the aid of an application roll.

Abstract: An impact resistant provided PMMA moulding material according to DE 195 44 563 is process into a surface-hardened film which is highly glossy, essentially free of gel bodies and can be processed in the “in-mould-film-decoration” method. The melted mass is generated by means of an extruder and fed to the inventive glazing rolls via a flexible lip nozzle, saild rolls being configured in order to generate an especially high locking pressure in the roll slit. The smoothing rolls are cambered. The films are used for decorating surfaces of high-value thermoplastic moulded parts.

Abstract: A polymeric film and method for making the film. Mixing a structural material with a secondary material to form a unitary mixture prior to processing forms the film. For a printable film, the secondary material is a printable material. The unitary mixture is extruded and heated so as to cause the printable material to bloom to the surface of the mixture. The result is a film that is stiffer and that lays flatter than prior multi-layered films that were prone to curling. The rollers used to stretch the film during this heat-setting stage are preferably very smooth so as to enhance the transverse-direction strength and stiffness of the film. In another embodiment of the invention, the secondary material is a clarity-enhancing material that may be styrene-ethylene-butadiene-styrene block copolymer. The blend combination is a suitable replacement for polyvinyl chloride films in that it is soft, conformable, flexible and clear.

The indicia preferably is in the form of a dot matrix pattern that is visible yet presents no barrier to the passage of smoke.

Abstract: In a first step, basic components including (A) 100 parts by weight of an organopolysiloxane gum, (B) 5-100 parts by weight of a reinforcing silica filler, and (C) 0.1-30 parts by weight of a processing aid are fed batchwise to a closed mixer for mixing them until uniform. In a second step, the mixture is continuously fed into a kneader/extruder for heat treating. The first step achieves quick dispersion and cooperates with the second step for the efficient production of a heat-curable silicone rubber compound.
