Abstract: Dispensed adhesive compositions including a core-sheath filament comprising a non-tacky sheath and an adhesive core comprising a polymer, where the dispensed adhesive composition is a product resulting from compounding the core-sheath filament through a heated extruder nozzle, where the dispensed adhesive composition is substantially free of chemical blowing agent decomposition byproducts or residues, and the dispensed adhesive composition exhibits an average density of less than 0.9 g/cm3 as measured by ASTM D3575-13 Suffix AA-Buoyancy test and peel force of greater than 30 N/cm as measured by ASTM D6862-11 test. Methods of dispensing such adhesive compositions are also disclosed.
