Abstract

Adhesive tape for bonding that can be detached without leaving residue and without damaging the surface of a substrate when stretched in a direction of a bond plane. An adhesive tape includes an elastomeric backing having opposing first and second surfaces an acrylate pressure sensitive adhesive disposed on at least one of the first and second surfaces of the backing. The backing includes a copolymer selected from the group consisting of polyether-polyester, polyether-polyamide, and a combination thereof and from about 20 to 60 wt % of a tackifier, based on the total weight of the backing. The backing has an elongation at break greater than 500%.
