Abstract: An adhesive composition may include at least about 2 wt. % and not greater than 49 wt. % of a (meth)acrylic based polymeric component A for a total weight of the adhesive composition, at least about 51 wt. % of a (meth)acrylic based polymeric component B for a total weight of the adhesive composition; and at least about 0.1 wt. % and not greater than about 30 wt. % of a tackifier component for a total weight of the adhesive composition. The (meth)acrylic based polymeric component A may be acidic and may have a glass transition temperature (Tg) of at least about 40° C. The (meth)acrylic based polymeric component B may be basic and may have a glass transition temperature (Tg) of not greater than about 20° C.

Abstract: A polyurethane foam may include an isocyanate polymer component and a polyol component. The polyol component may include a polyol having a molecular weight of at least about 500 kg/mol and not greater than about 6000 kg/mol. The polyurethane foam may have an elongation of at least about 500%. The polyurethane foam may further have a density of at least about 250 g/L and a tensile strength of not greater than about 1000 kPa.

Abstract: An adhesive may include an adhesive structure and an adhesive composition. The adhesive structure may include a graft copolymer. The adhesive composition may include at least about 1 wt. % and not greater than 40 wt. % of a macromonomer component for a total weight of the adhesive composition, at least about 50 wt. % and not greater than about 98 wt. % of a (meth)acrylic based polymeric component A for a total weight of the adhesive composition, and at least about 0.1 wt. % and not greater than about 30 wt. % of a tackifier component for a total weight of the adhesive composition. The macromonomer component may have a weight-average molecular weight of at least 1000 g/mol and a glass transition temperature (Tg) of at least about 40° C. The (meth)acrylic based polymeric component A may have a glass transition temperature (Tg) of not greater than about 20° C.
