  • High performance pressure sensitive adhesive tapes and process for making the same
    Patent number: 5100728
    Abstract: A pressure sensitive adhesive tape comprises a carrier layer having a thickness of 0.25 to 2.0 millimeter and comprising an electron beam cured pressure sensitive adhesive matrix, 10 to 20% by volume low density microspheres and at least one pigment in an amount sufficient to color the tape. Preferably, fumed silica is present in an amount up to 5% by weight. The tape preferably has a kin layer on each side of the carrier layer. The skin layer has a coating thickness of 25 to 125 g/m.sup.2 and comprises a pressure sensitive adhesive matrix free of rigid, low density microspheres. The process comprises first preparing an adhesive composition containing electron beam-curable adhesive polymer matrix, fillers and solvent. The composition is introduced and conveyed through a twin screw extruder. In the extruder, solvent is removed in one or more solvent removal units, and a solvent-free composition is extruded as the carried layer. Skin layers may be co-extruded with the carrier layer.
    Type: Grant
