  • Self adhesive tape
    Patent number: 6117531
    Abstract: Pressure-sensitive double-sided self-adhesive tape for permanent irreversible bonds, characterized in that the self-adhesive tape has a backing film based on rubbers having double bonds in the main chain, the rubbers being crosslinked such that they exhibit elastomeric behaviour, and a pressure-sensitive self-adhesive composition, based on an acrylate, which is coated on both sides of the backing film.
