Abstract
A polymer foam adhesive tape including: a substrate film; a polymer foam layer provided on one surface of the substrate film; a first adhesive layer provided on the polymer foam layer; and a second adhesive layer provided on the other surface of the substrate film, in which the polymer foam adhesive tape has a minimum compression load of 30 g to 300 g, a compression rate of the polymer foam adhesive tape is increased in proportion to a linear function according to an increase in pressure when pressure, which is equal to or more than the minimum compression load, is applied, and a thickness recovery rate of the polymer foam adhesive tape after pressure is removed is increased in proportion to a linear function as time passes.
