    摘要： Disclosed is an adhesive tape based on a co-extruded, three-layer polypropylene base film which has been biaxially stretch-oriented in at least three stages and has been subjected on at least one side to corona treatment. The base film comprises a base layer and two covering layers. The base layer comprises polypropylene. The covering layer adjacent the adhesive layer includes polypropylene modified with a natural or synthetic resin having a softening point of about 70.degree. to 170.degree. C., and the other covering layer includes polypropylene modified with a diorganopolysiloxane. The new adhesive tape possesses high values of mechanical properties. The tape has good printability, and it does not contain an adhesion-promoting layer for the adhesive, nor a separating layer (release coat), since such layers are not required. The tape can also be processed without appreciable draw-off noises.

    摘要： The invention relates to biaxially oriented, co-extruded polyester films. Said films comprise a base layer which consists of at least 70% by weight of a thermoplastic polyester, preferably polyethylene terephthalate (PET) with a diethylene glycol and/or polyethylene glycol content greater than 1.3% by weight and have at least one matt outer layer and optionally additional intermediate layers. The films also contain at least one UV-absorber, preferably hydroxy benzotriazoles and triazines. The films are characterized by high UV-stability, no embrittlement after exposure to temperature, a matt surface devoid of unwanted clouding and excellent thermoforming properties and are, together with the molded bodies produced therefrom, suitable for numerous interior and exterior applications. The (matt) outer layers can be identical or different and contain a mixture or a blend of a component I which consists of PET homopolymers and/or copolymers and a component II which is a copolymer resulting from the condensation product of isophthalic acid, an aliphatic dicarboxylic acid and a sulfomonomer with a copolymerizable aliphatic or cycloaliphatic glycol.

    摘要： A device for smoothing out the thickness of a sheet of thermoplastic material which includes a sheet die and a heating device which is integrated with the upper die lip of the sheet die. The heating device includes a hollow box filled with a liquid and a bar which projects laterally beyond the endfaces of the hollow box. The inlet and outlet openings of the bar in the hollow box are sealed. Arranged on the underside of the bar are small hot plates which are electrically heated. The liquid in the hollow box serves as a heat transfer medium and typically is an oil having a boiling point higher than 280.degree. C. The thickness profile of the extruded sheet is controlled, on the one hand, via controlling elements and, on the other hand, remaining thick and/or thin points of the sheet profile are smoothed by the bar of the heating device, in which the bar is progressively moved transversely with respect to the running direction of the sheet across the sheet width with the aid of a motor into a position in which the small hot plates are aligned with the thick/thin points to be smoothed. The corresponding thick/thin points of the sheet are smoothed by exposing the small hot plates to different temperatures or heating powers.
