Abstract:
1. An adhesive composition comprising: (1) a polyolefin composition comprising at least about 50 mol % of a polypropylene, and (2) at least one wax, wherein the at least one wax comprises a linear polyethylene wax having a molecular weight equal to or greater than 3000; and (3) wherein the adhesive composition is free of tackifier; (A) wherein the polyolefin composition has: (B) wherein the at least one wax has a viscosity at 140° C. of between about 100 cp and about 10,000 cp and a wax softening point greater than 110° C. such that a set time function F is greater than 1 and less than 3, wherein F is calculated according to the following equation: (C) wherein the adhesive composition has a set time greater than about 1 second and less than about 3 seconds as measured by Dot Set Time; and (D) wherein the adhesive composition has a fiber tear at 2° C. of about 20% or greater.
