A hot melt adhesive using polypropylene impact copolymers that is particularly well suited for elastic attachment and stretch films in diaper structures. The hot melt adhesive composition is a blend of about 2.5% to about 30%, by weight, of a polypropylene impact copolymer; about 2.5% to about 30%, by weight, of an olefin based elastomer; about 10% to about 70%, by weight, of a tackifying resin having a softening point of at least about 80&#xb0; C. and up to about 140&#xb0; C.; about 0% to about 60%, by weight, of a plasticizer; and about 0.1% to about 5% of a stabilizer or antioxidant.

Polypropylene impact copolymer based hot melt adhesive

A hot applied, non-crosslinking, non-butyl, sealant. These sealants are composed of olefin polymers, styrenic block copolymers, an ethylene vinyl acetate copolymer, tackifying resins, plasticizers, and preferably inorganic fillers, and organosilane adhesion promoters. Optionally, the sealant may include UV absorbers, antioxidants, pigments, and the like. The sealants are suitable for use as edge sealants for insulated glass (IG) window units.
