Abstract: A film (5) is extruded from plastic material (5a) by an extruder (1). The film is orientated after extrusion. Material is mixed into the plastic (5a) so that when the plastic film (5) is stretched, cavitation bubbles are formed in the material particles mixed into the plastic (5a). During the orientation, gas is arranged to act on the plastic film under high pressure so that the gas diffuses in the cavitation bubbles and causes overpressure in them. Thus it is possible to make a thin foamed film with a foaming degree over 70 %.

Abstract: An extrusion method and an extruder, the material to be extruded being fed with a material feeding device (1) into a radial pump unit included in the equipment. The radial pump unit comprises conical screws (2) which are adjacently positioned and rotate in the same direction. The radial pump unit transfers an annular flow of the material into the extruder's nozzle (4). Additional material (20) can be supplied into the product through the radial pump unit.

Abstract: An electromechanic film intended for transforming electric energy into mechanical energy and transforming mechanical energy into electric energy. The film (1) is dielectric and formed of cells (3), the ratio of the height and width of which cells is between 3:1 and 1:3. By joining two such films together and controlling them in such a way that in the first film (1) the electric field strength decreases and in the second film (1) the electric field strength increases, a bending acoustic element is provided.

Abstract: The invention relates to a method and an apparatus for making a plastic film, and to a plastic film. The invention comprises extruding a film (5) from plastic material (5a) by an extruder (1) and orientating the film after extrusion.

After orientation gas is arranged to act on the plastic film under high pressure so that the gas diffuses in the cavitation bubbles and causes overpressure in them.

Abstract: Film of dielectric material, which film contains gas bubbles preferably of a flat shape. To achieve improved electrical properties, the film is given a large internal unipolar charge, which is created by charging the film by means of an electric field intensive enough to produce partial discharges in the gas bubbles and to cause the charges to move into the dielectric material of the film.
