Low application temperature hot melt adhesive

摘要

High temperature performance hot melt adhesives are formulated for application at low temperature, i.e., below 300° F. Hot melt adhesive formed with metallocene polymer together with a maleated polyethylene wax show an excellent balance of high and low temperature performance and are particularly useful as packaging case and carton adhesive.

主权项

1. A low application temperature hot melt adhesive comprising a polyolefin copolymer component and a maleated polyethylene wax component,
wherein said polyolefin copolymer component comprises two different polyolefin copolymers comprising: (A) a first polyolefin copolymer that (i) is a metallocene-catalyzed ethylene/α-olefin copolymer prepared from ethylene and 1-octene monomers, and (ii) has a Melt Index of greater than about 400 g/10 min at 190° C.; and (B) a second polyolefin copolymer that (i) has at least about 50 mol % of ethylene content and (ii) has a Melt Index less than about 35 g/10 min at 190° C.
