Processing tapes have special properties to permit them to be used to prepare laminate articles, such as security articles. The processing tapes include a backing, a pressure sensitive adhesive layer and a release surface covering the pressure sensitive adhesive layer. The backing is a dimensionally stable transparent polymeric film, and the surface on which the pressure sensitive is coated may be a treated surface. The pressure sensitive adhesive is a transparent pressure sensitive adhesive that includes a crosslinked (meth)acrylate-based polymer and has a refractive index in the range of 1.45-1.55. The (meth)acrylate-based polymer includes alkyl (meth)acrylate monomers and may include acidic monomers.

The invention relates to a composite plastic part consisting of a plastic part (1) that has a rib structure (2), and (a) profiled support(s) (4) which is/are glued to the ribs and the longitudinal edge of which is arranged vertically or nearly vertically on the plastic base. The invention further relates to a method for producing such a composite part and finished products containing such composite parts as components.
摘要:
A transparent double-sided pressure-sensitive adhesive tape or sheet contains a transparent substrate and a transparent pressure-sensitive adhesive layer disposed on each side of the substrate, wherein the transparent pressure-sensitive adhesive layer disposed on at least one side of the transparent substrate is a layer formed from a pressure-sensitive adhesive composition containing a specific acrylic polymer (a) and a specific oligomer (b).
摘要:
A foam cushion tape comprising a compressible polyurethane foam layer having a first side and an opposite second side; a composite reinforcing film comprising an anchoring layer and a reinforcing layer, wherein the second aide of the polyurethane foam is disposed on the anchoring layer of the reinforcing film; a first adhesive disposed on the first side of the compressible polyurethane foam; and a second adhesive disposed an the reinforcing layer of the composite reinforcing film. The anchoring layer comprises at least one non-olefinio polymer, such as polyvinylidene chloride (PVDC), polyurethane, nylon, or the like. A method for the manufacture of thin, foam cushion tapes for flexographic printing is provided, comprising casting a curable polyurethane foam composition directly onto the anchoring layer of a composite reinforcing film having a first anchoring layer and a second reinforcing layer, followed by curing the foam composition to form a compressible polyurethane foam.
