MICROSPHERE CONTAINING ELECTRON BEAM CURED PRESSURE-SENSITIVE ADHESIVE TAPES AND METHODS OF MAKING AND USING SAME

摘要

The present invention provides pressure sensitive adhesive tape including at least one electron beam cured (EB-cured), rubber-based pressure sensitive adhesive (PSA) core including microspheres. The core layer is coated on at least one side, and in one embodiment, on both sides, with a skin layer including an EB-cured rubber-based PSA that is substantially free of microspheres. The core layer may comprise a lamination seam, a second core layer or a non-woven support layer.
