  • Publication number: 20210032502
    Abstract: Brittle acrylic films are made from impact-modified polyalkyl (meth)acrylate and are useful in forgery prevention labels containing the same. The films can be advantageously prepared by extrusion and, depending on the desired purpose, can be designed to be translucent or entirely non-transparent e.g. white. Ideally, the brittle acrylic films and the forgery prevention labels have no intended break points such as slits, perforation etc.

  • Patent number: 10611130
    Abstract: An extruded matt foil has at least one layer in which glass beads are uniformly distributed in a polymer matrix with at least one fluoropolymer and at least one further layer. The matt foil has a particularly high UV-resistance, a high weathering resistance and excellent mechanical properties. Therefore, the foil is highly suitable for surface-protection of materials such as polyvinyl chloride (PVC) and for use in high-pressure laminates (HPLs).

  • Patent number: 9987828
    Abstract: The present invention relates to novel matt PMMA foils for application on materials as foil providing protection from weathering effects and as decorative foil. In particular, the present invention relates to a novel, at least two-layer PMMA foil which features particularly good adhesion on the substrate. The outer layer here exhibits the mattness, and the inner layer here comprises a low-molecular-weight component which improves adhesion on the substrate.

  • Publication number: 20170197391
    Abstract: The present invention relates to novel films for application on materials as protective film in respect of weathering effects. In particular, the present invention relates to a novel film composite which has at least three layers and which features particularly good adhesion on the substrate and particularly good optical properties. The outermost layer here is a layer comprising a fluoropolymer, the middle layer is a PMMA layer comprising at least one UV absorber and/or UV stabilizer, and the innermost layer is a PMMA layer comprising at least one adhesion promoter which improves adhesion on the substrate.

  • Patent number: 8158709
    Abstract: The present invention relates to a plastics mixture comprising at least one thermoplastic polyurethane A) and at least one impact-modified poly(meth)acrylate B), where the impact-modified poly(meth)acrylate comprises a hard phase whose glass transition temperature is at least 70° C. and a tough phase whose glass transition temperature is at most ?10° C., the average particle size of the tough phase is at most 130 nm, and at least a portion of the tough phase has covalent linkage to the hard phase.

  • Patent number: 8092731
    Abstract: The invention relates to a method for producing a thermoplastic plastic film. According to said method, the thermoplastic plastic is melted and transported in an extrusion installation comprising an extruder, an extrusion nozzle with a wide-slot delivery opening and a chill roll, which is fixed to a roll system and then leaves the delivery opening of the extrusion nozzle in the form of a flat melted web. Said melted web is then applied to the chill roll and is cooled. The invention is characterised in that it uses an extrusion installation, in which the distance between the delivery opening of the extrusion nozzle and the surface of the cooled roll does not vary by more than +/?50 ?m during the operating time. The invention also relates to a film of this type and to uses of the latter.
