ELASTIC ATTACHMENT ADHESIVE AND USE THEREOF

摘要

The present invention relates to elastic attachment adhesives that comprise non-metallocene catalyzed polymers. The elastic attachment adhesives have stable creep performance under prolonged aging parameters, making these adhesives particularly well suited for elastic applications.

主权项

1. An elastic attachment hot melt adhesive comprising a tackifier and a polymer having a viscosity lower than about 200,000 mPas at 200° C. in accordance with ASTM D3236;
wherein the polymer comprises a non-metallocene catalyzed polymer degraded with peroxide and/or heat; and wherein the non-metallocene catalyzed polymer is a polypropylene homo or copolymer with a heat of fusion greater than 20 J/g measured in accordance with ASTM D3418-12; wherein the adhesive has a tan δ value of greater than about 30 at the adhesive application temperature; and wherein the amount of tackifier is less than the amount of the polymer in the adhesive.
