A pressure-sensitive adhesive and tape are provided having a rubber component (30-60 weight percent) of polyisoprene (4-55 weight percent) blended with a styrene-isoprene-styrene block copolymer (96-45 weight percent) and a tackifying component (70-40 weight percent) to provide an adhesive that exhibits superior adhesion performance to low surface energy substrates.

Pressure-sensitive adhesive and disposable diaper closure system

A tape closure system exhibiting high shear and high non-shocky peel to a low adhesion backsize coated substrate is disclosed. The adhesive used on the fastening tape used in the closure system comprises a high diblock (.gtoreq.25 percent) styrene-isoprene-styrene elastomer component with a composite midblock glass transition temperature of 244 to 264 Kelvin with 30 to 60 percent elastomer.
