Heat-activable adhesive sheet of an adhesive comprising a blend of at least three synthetic nitrile rubber compositions S1, S2 and S3, each of which comprises at least one synthetic nitrile rubber, and at least one reactive resin which is capable of crosslinking with itself, with other reactive resins and/or with the nitrile rubbers of synthetic rubber compositions S1, S2 and S3, in which a) the blend of the heat-activable sheet being microphase-separated, characterized by at least three different glass transition temperatures in a DSC, b) at least one of said glass transition temperatures being greater than 10° C. and at least one of said glass transition temperature lower than −20° C., c) the nitrile rubber or rubbers S1 having an acrylonitrile fraction of greater than/equal to 35%, d) the nitrile rubber or rubbers S2 having an acrylonitrile fraction of greater than 25% and less than 35%, e) the nitrile rubber S3 having an acrylonitrile fraction of less than/equal to 25%.
摘要:
A pressure-sensitive adhesive tape having pressure-sensitive adhesive layers on a top side and a bottom side, and a carrier film between the adhesive layers, wherein there is a white coating layer at least between the pressure-sensitive adhesive layer on the top side and the carrier film and there is a metallic layer at least between the pressure-sensitive adhesive layer on the bottom side and the carrier film. The pressure-sensitive adhesive tape is useful to bonding parts of optical liquid crystal displays. Optical liquid crystal displays containing the pressure-sensitive adhesive tape are also disclosed.
摘要:
An adhesive tape bonds a reflecting film in a rear illumination unit of a liquid crystal display system. The adhesive tape has a backing film layer and two pressure-sensitive adhesive composition layers with a total thickness (average value) of less than 30 μm and a standard deviation of the total thickness of less than 1.25 μm.
摘要:
The invention relates to a pressure-sensitive adhesive tape, particularly for producing or sticking together optical light crystal data displays (LCD's), comprising a top side and an underside, with light-reflective properties on the top side and light-absorbing properties on the underside. The pressure-sensitive adhesive tape also comprises a carrier film with a top side and an underside, which is provided with a metallic reflective coating on at least one of its sides. The pressure-sensitive adhesive tape is provided with a pressure-sensitive adhesive layer on both sides and is characterized in that the carrier film has a content of antiblocking agents of less than 4000 ppm, and at least one light-absorbing chromophoric layer is provided at least between the underside of the carrier film and the pressure-sensitive adhesive layer located on this side.
摘要:
The invention relates to a contact-adhesive tape, in particular for producing or bonding optical liquid crystal data displays (LCDs), said tape comprising an upper face and an underside. The tape also comprises a backing film (a) with an upper face and an underside, both the upper face and the underside of said tape being provided with a respective contact-adhesive layer (b, b′). The contact-adhesive layer on at least one side of the contact-adhesive tape is black.
摘要:
The invention relates to a pressure-sensitive adhesive tape, particularly for producing LCD displays, comprising two surfaces while also being provided with at least one support having two supporting surfaces and a pressure-sensitive layer on each of the two supporting surfaces. The invention is characterized in that at least one of the two surfaces of the pressure-sensitive adhesive tape has silvery reflective properties.
